RWMA Class 3 C18150 Copper Round Bar
CuCr1Zr – UNS.C18150 Chromium Zirconium Copper C18150 is an excellent and unique copper alloy with high electrical conductivity, hardness, and ductility, moderate strength, and excellent resistance to softening at elevated temperatures. The addition of 0.1% zirconium (Zr) and 1.0% chromium (Cr) to copper results in a heat treatable alloy which may be solution treated and subsequently aged to produce these desirable properties. Rod is usually supplied from the mill in the fully aged and drawn condition so no further heat treatment is required by the fabricator. The softening temperature of properly heat treated C18150 rod exceeds 500°C as compared to unalloyed pure copper which softens at 200°C, and silver bearing coppers which soften at 350°C.
Furthermore, many evidences shows that C18150 can provide less sticking and resisting deformation longer than its C18200 counterpart in some specific situatons.
Typical Application for C18150 Chromium Zirconium Copper Alloys:
Electrical Industry: Resistance Welding Electrodes, Circuit Breaker Switches
Consumer: Rod Extensions, Pencil-type, Light Soldering Guns, Tips
Industrial: Welding Wheels, Tips and Rod extensions for resistance seam and spot welding
C18000 Details & Applications: C18000 Copper Chromium Nickel SilicoN
CuCrNi2Si – UNS.C18000 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.
