C18000 Copper Nickel Silicon Chromium-RWMA Class 3

MasterSource offers a complete line of Copper Alloy C18000 inventory as noted below.

Copper Alloy UNS C18000

Heat treatable copper alloys with a combination of high tensile strength and good electrical and thermal properties. Should be used in heat—treated condition.

High hardness makes them ideal for electrodes for spot and seam welding of high resistance materials such as stainless steels, nichrome, inconel, and monel metal. As a casting, they are used for flash, butt and projection welding electrodes and fixtures. Other uses are welding gun components, seam welding bearing and other current carrying structural parts.

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 are required. C18000 offers excellent value for the properties it offers. C18000 is a viable substitute for C17500 and C17510 in many applications.
