Special Alloy Copper

Special Alloy Copper

Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. The most well-known copper alloy families are brass (copper-zinc), bronze (copper-tin) and copper-nickel. These actually represent families of alloys, all made by varying the amount of specific alloying elements.Beryllium-copper in the fully heat treated and cold worked condition is the hardest and strongest of all copper alloys. Its mechanical properties are similar to many high strength alloy steels, but it has better corrosion resistance as well as electrical and thermal conductivity than any of them.

It is malleable, ductile, and an extremely good conductor of both heat and electricity. It is softer than zinc and can be polished to a bright finish. It is found in group Ib of the periodic table, together with silver and gold. Copper has low chemical reactivity. Copper and copper alloy in the automotive industry are mainly used for radiators, braking systems, hydraulic equipment, gears, bearings, brake linings, power distribution and power systems, gaskets and all kinds of joints, fittings and accessories, etc.
