Copper Nickel Silicon Chromium C18000, RWMA Class 3, AWS J1.3

 

Copper Nickel Silicon Chromium is a very hard heat treatable copper with moderate electrical conductivity. C18000 is utilized when a combination of very good mechanical strength along with moderate electrical and thermal electrical conductivity is required. It offers excellent value for the properties and is a high-value substitute for C17500 and C17510 in many applications as it meets RWMS Class 3 Specifications. Refer to Cadi MOLD-MOR 1® for mold applications.

 

Typical usages of RWMA Class 3 copper alloy: C18000 is recommended for spot and seam welding of high resistance alloys such as stainless steel. Other uses include flash welding dies, backup bars, and projection welding electrodes.
