Mechanical values above are typical for 1" solid diameter Hard (35%) Temper
*Hardness conversions are approximate
**Test values are nominal approximations and depend on specimen size and orientation
The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable ASTM specification references.

With C18150 RWMA Class 2 Copper the zirconium in addition to chromium copper improves creep resistance at high operating temperatures and reduces sticking of electrodes to the work during spot welding of galvanized materials. C18150 is specified mainly for electrode applications. C18150 specifically is for cap style resistance welding electrodes and weld wheels. This alloy is used for spot and seam welding of cold and hot rolled steel, stainless steel and low conductivity brass and bronze. They are also used as flash welding dies, and as electrodes for the welding of galvanized steel and other coated materials.
