Beryllium copper(BeCu) is also known as copper beryllium(CuBe),is a copper alloy with 0.3-5% beryllium and other elements.Beryllium copper alloys have high strength,good electrical and thermal conductivities etc. characteristics.There are two types of beryllium copper alloys,high strength alloys and high conductivity alloys.The high conductivity beryllium copper alloys contain 0.3-0.60% beryllium and 1.5-2.0% nickel and balance copper.High conductivity beryllium copper alloys are usually used on resistance welding field.
