Copper sheets are made up of 99% pure copper. Bronze and brass are alloys of copper. Technically speaking, when the alloy is a mixture of copper and tin or leads, they are considered bronzes, while the mix of copper and Zinc are considered brasses. There are many varieties of alloys possible depending upon the chemical composition. Their names also vary accordingly, such as commercial bronze, cartridge brass, Muntz metal, nickel silver, etc. The colour of the metal also varies depending upon the composition.
Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. But it is not very strong or hard. Copper is cold workable. Its strength and hardness increase during the cold working process when impact forces cause the formation of elongated crystals.

Copper has a distinct colour and luster as compared to other metals. Pure copper is of orange-red colour and acquires a reddish tarnish because of cupric oxide formation when exposed to air.
After silver, copper is the immediate best metal in thermal and electrical conductivity. Therefore copper is used in electrical equipment such as motors and transformers in the form of wires and windings and in heat exchangers as heat sinks. This is because it conducts both heat and electricity very well.
Copper is also used in decorative art. Copper sheets are beaten to produce intricate patterns. Copper compounds are used as pigments that are used in paintings. Copper is used as a base metal for coverage applications of precious metals such as gold and silver in jewellery to improve their elasticity and hardness. Copper also processes an important medicinal property. It is very resistant to bacterial attacks.

Copper is available in standard Rolls, Plates, Profiles, Angles, and Channels. Copper is generally specified by hardness such as soft, half-hard, fully hard, and by weight, in grams per square meter. Example, 70 GSM, 75 GSM, 80 GSM,etc.,
