C18000 Copper Chromium Nickel Silicon

CuCrNi2Si a UNS.C18000A Copper Chromium Nickel Silicon Alloys which also called Beryllium Free Copper alloy meets the mechanical requirements of RWMA Class 3 Copper is a very hard heat treatable copper based alloy with an economical higher strength and high conductivity and C18000 Alloys is utilized when a combination of very good mechanical strength along with moderate electrical and thermal electrical conductivity are required. Furthermore C18000 alloy is an excellent substitute for copper beryllium alloys C17500 and C17510 in terms of many applications.
