Copper alloy is made by adding a small addition of elements such as nickel, silicon, chromium and beryllium in the pure copper. The adding elements make it ideal for applications where a combination of high strength and excellent corrosion resistance is required. Cooper alloys are widely recognized for their excellent resistance to stress corrosion cracking and corrosion fatigue.
There are more than 400 copper alloys, each with a unique combination of properties to suit many applications, manufacturing processes and environments such as Brass (copper-zinc alloys), Bronze alloys, Copper-nickel alloys, Nickel-nickel-zinc alloys and Beryllium copper alloys.
Areas of application:
Copper alloys are frequently used for applications requiring high electrical conductivity and superior mechanical strength. Beryllium copper alloys is widely used for injection molding tools or as cores and inserts in steel molds. Copper-nickels are mainly used for seawater service as forged and machined valve and pump components, fittings and hardware. Used where high corrosion resistance is required and where concern over chloride stress-corrosion cracking prevents use of stainless steels.
