Copper alloy is made by adding a small addition of elements such as nickel, silicon, chromium and beryllium in 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. LKALLOY is an industry-leading manufacturer and supplier of beryllium copper, copper-nickel, and a wide variety of mixed copper alloys. These alloy grades are among the most important and widely used copper alloys due to the impressive range of attributes that can be attained.
Areas of application
Copper alloys are frequently used for applications requiring high electrical conductivity and superior mechanical strength. Beryllium copper alloys are widely used for injection moulding tools or as cores and inserts in steel moulds. 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 the use of stainless steel.
