Why is copper a good conductor of heat?

In today’s era, nobody can live without electricity. It is the need of everyone in every part of the world in every corner. Each and everyone is associated to each and every field need electricity but have you ever wondered that how the electricity came into existence or more appropriately to say that how is the electricity present in all the corners of the world. Well, the basic cause is that we use the copper wire for the transmission of electricity. Thus copper is the greatest conductor of heat and electricity.

Now the question arises that why are we relying on copper? Well, we can say that all the metals present in nature are one way or the other very good conductors of heat. Some are very good some are a little bad. The metals are the solid chemical elements. To study the basic atomic structure of a specific metal atom, they have some of the valence electrons in their valence shell. The valence shell is the last shell of the atom. Every atom requires stable state at every state, to attain stability an atom needs to have eight electrons in its last shell.

The atoms either can lose some of the electrons for stability or they can just gain them so that they could attain the stable electronic configuration. The metals generally have one to four electrons in its valence shell. Thus they usually lose the electrons. The electrons are the negatively charged particles; due to this they usually give some additional charge to the substance. When a metal loses its electrons they will certainly heat up as there will be the increase of the free electrons. The free movements of electrons will certainly increase the heat and electricity conductivity.

The basic configuration of copper is:
Symbol: Cu
Atomic number: 29
Atomic mass: 63.54 AMU
Ionic charge: +3
Valency: 3

In the electricity applications, there is the number of copper uses. Most of the metals are considered as the very good conductors but copper is the best and it loses three electrons at the room temperature. All the copper atoms together can lose a very large number of electrons and thus can conduct the electricity in a huge amount. The copper is also a very cheap metal thus is used in all sort of applications. 

There are many of the applications of copper in the field of electricity:
        Wiring of electricity at home, offices, schools, shops, malls, etc.
        For the automated induction of electricity in the generators and invertors which are used in the cases of power cut and loss of electricity.
        Used in the capacitors for the conduction of electricity in the batteries.

In the thermal heating process the copper is used as:
        It is used in making the bottom surfaces of the utensils as it has the good heat conduction.
        It is used for the heat exchanger in the hot water tanks.
        This is also used as the heat sinks in the computers, the disk drives, the TVs sets, and many more things.

These are some of the uses of copper in the conduction of heat and electricity.

Stainless Steel Pipe types

Stainless steel is a flexible material comprised of a steel alloy and a small proportion of chromium—the addition of chromium adds to the material’s resistance to corrosion, an attribute that earned stainless-steel its name. Because stainless-steel is additionally low-maintenance, oxidization resistant, and doesn’t have an effect on other metals it comes in contact with, it’s oftentimes utilized in a large array of uses, particularly in piping and tubing manufacturing. Based on the end use of the pipe, stainless-steel piping is distinguished into many categories.
Stainless Steel Piping
Pipes and tubes are sometimes difficult to classify and have a tendency to be classified based on function. In addition to these classifications, stainless-steel is additionally distinguished by type and grade. For tubing and piping uses, type 304 stainless-steel is a common choice as a result of it’s extremely chemical and corrosion-resistant. However, stainless-steel 304 pipes aren’t compatible with uses wherever temperatures fall between 800 and 1640 degrees Fahrenheit (F) as a result of it is prone to carbide precipitation, a result of the material’s .08 % carbon content limit. Stainless-steel type 304L circumvents this problem because it’s a lower carbon content limit, and thus is subjected to welding and higher temperature uses. Alternative types of stainless-steel often possess additives (such as nickel or molybdenum) that strengthen traits that are fascinating above all uses.

Stainless Steel tube for General Corrosion-Resistance
This general category of steel is appropriate for uses that require resistance to corrosion on top of other traits. Ferritic or martensitic types of steel (those made with the most chromium) are manufactured to be either heat-treated or annealed. austenitic stainless steels (those with high chromium and nickel contents) give even extra resistance and can be used under constant general conditions as ferritic and martensitic types.

Stainless Steel Pressure Pipe
This type of stainless-steel pipe is formed from either solid chromium or a chromium and nickel combination. types of stainless-steel pressure pipe include seamless and welded pipe, electrical fusion welded pipe for hard-hitting uses, large diameter welded pipe for corrosive or high-temperature uses, and seamless and welded ferritic and austenitic stainless-steel pipe.

Stainless Steel sanitary tube
For uses where stainless-steel tube or piping comes in touch with food and other sensitive product, sanitation is a high priority. Stainless-steel sanitary tube is employed in such uses as a result of its high corrosion-resistance, doesn’t tarnish, and is simple to keep clean. For specific uses, different tolerances can be achieved. The grade typically used for these uses is ASTMA270.
Stainless Steel Mechanical Tubing
In uses like cylinders, bearings, and other hollow formed components, stainless-steel mechanical tubing is usually used. Tubing can be manipulated to possess a range of cross-sectional shapes, like square and rectangular, additionally to the more traditional, round tubing cross-section.
Stainless Steel aircraft tubing
In highly-specific aircraft uses, chromium and nickel type stainless-steel is used as a result of their heat and corrosion-resistance. Found in uses that need high-strength, stainless-steel aircraft tubing is work-hardened or welded, although work-hardened pieces shouldn’t be used with some types of corrosive substances. Low-carbon types of stainless-steel are a standard choice for welded elements.
Aircraft Hydraulic-Line tubing
Another type of aircraft tubing is used in aerospace uses as fuel-injection lines and hydraulic systems and tends to be small. It is usually manufactured from stainless-steel 304L Tubing because of the steel’s high-strength, corrosion-resistance, and ductility.


Gasket and Its Types

A gasket might be defined as a flexible component that sits in-between two other surfaces generally to prevent leakage from or into the joined objects while under compression. Gaskets are commonly manufactured by cutting from sheet materials.



Types of Gasket
1)  Sheet gaskets
When a sheet of metal has the gasket shape "punched out" of it, it is a sheet gasket. These gaskets can fill various different chemical requirements based on the dormancy of the material used. Non-asbestos gasket sheet is longlasting, made of multiple materials, and thick in nature. Applications using sheet gaskets involve acids, corrosive chemicals, and steam. Flexibility and good recovery prevent breakage during installation of a sheet gasket.

2)  Solid material gaskets
The idea behind solid material is to use metals which can't be punched out of sheets, however, are still low-cost to manufacture. These gaskets typically have a {much|a way|a far} higher level of quality control than sheet gaskets and customarily can withstand much higher temperatures and pressures. The key drawback is that a solid metal must be greatly compressed so as to become flush with the flange head and stop leakage. the material choice is more difficult; because metals are primarily used, process contamination and oxidization are risks. a further drawback is that the metal used should be softer than the flange — so as to make sure that the flange doesn't warp and thereby stop sealing with future gaskets. Even so, these gaskets have found a distinct segment in the industry.

3)  Spiral-wound gaskets
Spiral-wound gaskets comprise a combination of metallic and filler material. Generally, the gasket features a metal wound outward in a circular spiral with the filler material wound in the same manner, however, ranging from the opposing side. This leads to alternating layers of filler and metal. The filler material in these gaskets acts as the sealing part, with the metal providing structural support.
These gaskets have evidenced to be reliable in most applications, and permit lower clamping forces than solid gaskets, albeit with a higher value.

4)  Kammprofile gaskets
Kammprofile gaskets are used in many older seals since they have both a flexible nature and steady performance. Kammprofile work by having a solid corrugated core with a flexible covering layer. This arrangement allows for very high contracting and an extremely tight seal along the ridges of the gasket. Since generally, the graphite will fail instead of the metal core, Kammprofile can be repaired during later inactivity. Kammprofile has a high capital cost for most applications but this is countered by long-lasting life and increased reliability.

5)  Fishbone Gaskets
Fishbone Gaskets are a direct substitute for Kammprofile and Spiral wound gaskets. They are fully CNC machine manufactured from similar materials but the design of the gaskets has eliminated inherent shortcomings. The rounded edges do not cause flange damage. The added "Stop Step" prevents the Fishbone gaskets from being over compressed/crushed, often caused by hot torque techniques on plant startup. The bones of the gasket remain ductile and adjust to thermal cycling and system pressure spikes resulting in a long-lasting and steady flange seal that outranges all other gaskets of this nature significantly.

6)  Flange gasket
A flange gasket is a type of gasket made to fit between two sections of pipe that are flared to provide a higher surface area.
Flange gaskets are available in a variety of shapes and sizes and are categorized by their inner and outside diameter.
 The gaskets for flanges can be divided into major 4 different categories:
1.   Sheet gaskets
2.   Corrugated metal gaskets
3.   Ring gaskets
4.   Spiral wound gaskets

What are different types of carbon steel?

Carbon steel contains manganese and iron and it is considered to be one of the widely used steel metals. This is used for various construction processes and is known for its high-quality features. The word carbon steel may also be used in reference to steel which is not stainless steel. In carbon steel, the higher carbon content is present and it is basically a combination of two elements, iron, and carbon. Other elements are present in very fewer quantities. It is basically a metal alloy that is made up of iron and carbon mixed together and the amount of carbon to the steel varies depending for which purpose the carbon steel is required.

Carbon steel is used for various fields for various purposes. It is used in applications such as aerospace, manufacturing, constructions, telecommunications, and more. To learn more about carbon steel and its types and usage, keep reading this article continue.

There are basically four types of carbon steel is available and which is based on the amount of carbon present in the alloy. Below are mentions the various types of carbon steel:

1.    Low carbon steel: it contains approximately 0.05% to 0.25% carbon content with up to 0.4% manganese. It is also known as mild carbon steel, it is low-cost material that is easy to shape, and the surface hardness can be increased by carburizing process.

2.    Medium carbon steel: it contains approximately 0.29% to0.54% carbon content with 0.60 to 1.65% manganese content. This type of carbon steel maintains ductility and strength and has good wear resistance.

3.    High carbon steel: it contains approximately 0.55% to 0.95% carbon content with 0.30 to 090% carbon content. It is very strong, used for springs and high-strength wires.

4.    Very high carbon steel: this type of carbon steel contains 0.96% to 2.1% carbon content; it is used to produce specific atomic and molecular microstructures.

Uses of carbon steels:-
·         Low carbon steel is transformed into flat-rolled sheets and strips, and used for shipbuilding, wire, vehicle bodies, and domestic appliances. It is widely used for fabrication, and paneling because it can’t be altered by heat treatment. It is also called wrought iron because it has the lowest amount of carbon, used for fencing, gates, and railings, hard but not brittle.

·         Medium carbon steel is a lot easier to the machine and adding some small amounts of silicon and manganese improves its quality. It is commonly used in buildings and bridges, axles, gears, shafts, rails, pipes, tubing and couplings, cars, fridges, and washing machines.

·         High carbon steel has much better tensile strength; it is used to make cutting tools, blades, punches, dies, springs and high – strength wires.

·         Ultra high carbon steel is brittle and very hard, and it cannot be cold work. It is used to make extremely hard components like blades, cutting tools and large machine parts, hot water radiators, industrial castings, and metal lamp posts.  It is also called cast iron and used to make old-fashioned cooking pots and utensils.


These are the types and usage of carbon steel and you can buy it as per your budget and requirement.

Why brass alloy is used for making bullets and weapons?

The brass bullet is generally considered to be better than the other cased bullets because it creates a chamber steel, thus you experienced less blowback into the chamber and the receiver. It is better at sealing action because it is more malleable, so it efficiently expands to more snugly fit the walls of the gun chamber. The gun throws back less gas and unburned powder every time when it's fired.

The brass has the softer property and it is more malleable, it can be easily reloaded. Brass can be reliably reshaped to its original dimensions. We can say that resizing of the gun case because gun folk is the simple and direct lot of the time. Practically, when you reload the bullets, this won't be much concern for you. For the high volume shooters and those who want to get the most bangs for their money, it is something that has to be considered. The brass has the excellent property of corrosion resistance and it is slicker. So while you find lots of brass bullets that are coated for more reliability, it is not necessary for most of the time.

Why only use brass bullets?
You may hear lots of opinions and controversies when it comes to choosing brass bullets than other alloy metal bullets. For example, most of the people think that steel bullets cause more fouling because of its lacquer coating and most of the breakdown occurred when shooting steel ammo. Brass is the mixture made alloy from zinc and copper. It is a good metal because when it is fired, it expands very quickly and shrinks back down rapidly. When it is fired off, the neck expands and seals the chamber and fewer malfunctions in occurred gunman.

Most of the guns are meant to design fire brass bullets for this reason brass performs accurately in the gun system.  Brass is more accurate than other bullets, due to its better seal on the chamber and creates less fouling. The main disadvantage of brass bullets are price, for those who are willing to buy bullets in the budget then it is going to be more expensive. It is primary case alloy for most of the bullets for a couple of reasons, some are given below:

        These are soft enough  to expand and fill in a chamber
        Not split during the fire
        Does not harm the gun parts
        Do not spark with other metal parts
        It can be reloaded many times

There are numerous advantages of brass bullets, however, the large con of brass bullets is that they tarnish, especially when uses many times. Brass can be stored in harsh conditions and kept in leather holsters.

Advantages-
  1.         The brass is more corrosion resistant
  2.          It has the lower coefficient of friction, which allows slicker feeding in semi-auto guns
  3.         Easier to sliding rounds on top of each other in the magazine
  4.         It is easier to load and unload in each gun round
  5.         Brass looks different, allows easier identification of brass at the range of a special load.
So these are the reasons why brass is good for making bullets and weapons.

What kind of body armor steel does the military use for body armor?

Armor steel and ballistic steel are designed for some wide variety of military specification and structural usage. These usages require the armor steel plate which is approved by all the military departments and agencies which are having the combat and the defense applications. These steel plates are being utilized in the manufacturing of vehicles. They are used to build the structural housing with the high protection which consists of armaments and other protective structures and varied applications.

How the armor for the military should be designed?
This is a very oblivious thing that the people in the military need full protection. Thus they require the best armor so that they can protect themselves from most of the dangers. The armor made from this steel is not just for the chest but also for the head, face, groin and other parts of the body. The major aspect of the military armor is that they do their job very properly. If a soldier is not having full protected body armor then they won't be able to perform well in the high-risk operations like the situations in the war zone. This will gradually be a loss for the country.



The body armor may seem like a little heavy and inflexible, in which the person won't be able to move properly. This will naturally result in extreme discomfort. The soldier's work is the hardest work; they have to work in the very hostile environment. It could be hot, it could be cold also it could be rainy or may be humid, but the soldiers have to still perform their duty. There could also be situations when they have to wear their armor for the whole time. Thus the military man needs his armor to be thinner, lighter, and comfortable but more importantly protected.

Most of the militaries minimize the cost of the armor by outsourcing the body armor researches to the manufactures of the armor. Different militaries have their own research department which is focused on body armor. Their research focuses on creating the armor that is compatible with the one carrying them. They have to make the ballistic steel armor plates thinner. This will reduce the cost which will certainly be manufactured with the multi-threat protection. The armors are very good for the combat attacks within the close quarter's weapons and also the protection from the explosives and fragmentations.

The militaries have to protect and prevent against a wide range of the attacks. More often they prevent extreme attacks which involve the high caliber. There may also be the piercing rounds which may be difficult for a person. These threats and attacks can only be ignored by wearing the hard armor which is made of the ceramic, steel and more specifically the titanium.

Along with the armor to be protected it should also be of the proper fitting and size. This is very true for the female soldiers. Most manufacturers made the armors made of armor steel and ballistic steel which are having the very good fitting.
