Clad Steel Plate is a composite steel plate made by bonding

stainless steel, etc. (cladding material) to either or both sides of carbon steel or

low-alloy steel (base metal). Clad steel plate combines the necessary strength of a

structural material (base metal) with the resistance to heat and corrosion (cladding

material). Moreover, it offers substantial economic benefit, because it costs

substantially less than a plate made entirely of the cladding material.
Gilding

Metal Clad Steel Strips refer to the copper alloy, comprising 95% copper and 5%

zinc. Technically, it is brass. Gilding metal is used for various purposes, including

the jackets of bullets, driving bands on some artillery shells, as well as enameled

badges and other jewelry. It is a special kind of brass, with a high percentage of

copper, used to make objects which are to be gilded by electrolysis.

Like bullets, Cups for

Military can be identified as having been fired by a specific firearm. The

time when cartridges are loaded into a firearm the potential for the transfer of

unique tool marks exists. However, the cartridge does not have to be fired for these

marks to be transferred. Simply loading a cartridge into a firearm can generate a

unique identification mark that can be easily identified.


Cartridge Case Cups are mostly made of brass but can also be made of other

materials such as steel and plastic. Cartridge cases come in a variety of finishes

but the material used in cartridges is usually softer than that of a firearm. The

surface of the cartridge case that meets the inner workings of the firearm may be

marked.
Tool marks produced on the cartridge cases will be in two basic forms. As the

microscopic striations found on bullets, cartridge cases can pick up striated action

marks. These "scratches" are produced when the cartridge case moves

laterally against the tool producing a scrape or striated mark. The other forms of

marks that can be left on a cartridge case are impressed with action marks.

Impressed marks are created on cartridge cases when it impacts the tool (again, the

firearm) with adequate velocity or pressure to leave an impressed or indented mark.
Cartridge Bullet Cups are compared to fired standards from a firearm

using a comparison microscope as described on the bullet identification page.

Standards are first examined to determine what marks, if any, the firearm is

consistently reproducing. Evidence cartridge cases are then directly compared to the

standards to see if they too are also similarly marked. In the case of Gunwantlal v.

State of M.P it was held that “ From the perusal of the record it can be safely

inferred that the presence of a live cartridge in the handbag was not within the

knowledge of the petitioner and petitioner did not have requisite mens rea for

committing the said offence.”


Meaning and Components of Cartridge
A cartridge or around is a type of pre-assembled firearm ammunition packaging a

projectile. a propellant substance and an ignition device within a metallic, paper or

plastic case that is precisely made to fit within the barrel chamber of a breech-

loading gun, for the practical purpose of convenient transportation and handling

during shooting. Although in popular usage the term "bullet" is often used

to refer to a complete cartridge, it is correctly used only to refer to the

projectile.
There are several different words used to describe ammunition: bullets, shells,

projectiles, rounds, shot, slugs, cartridges, munitions, etc. In reality, anything

can be used as ammunition, whether it be a stone you are throwing or words you are

using in an argument. In the world of firearms, it is most commonly referred to in

the informal context as “ammo.” Many people call them bullets, which to some is

like nails on a chalkboard because the correct term for firearms ammunition is

“cartridge.”
Copper Clad Steel

(CCS), also known as copper-covered steel or the trademarked name Copperweld is a

bi-metallic product, mainly used in the wire industry that combines the high

mechanical resistance of steel with the conductivity and corrosion resistance of

copper. It is mainly used for grounding purposes, line tracing to locate underground

utilities, drop wire of telephone cables, and inner conductor of coaxial cables,

including thin hookup cables like RG-174 and CATV cable. It is also used in some

antennas for RF conducting wires.
The first recorded attempt to make copper clad steel wire took place in the early

1860s. Although for over 100 years people had been suggesting various ways of uniting

copper and steel, it was not until the period mentioned that Farmer and Milliken

tried wrapping a strip of copper about a steel wire. American engineers in 1883 and

again in the 1890s made attempts to produce a copper-steel wire, in one instance at

least, by electroplating copper on steel.
