C18150 Copper Chromium Zirconium Alloy

Short Description:

Class 2 Alloy C18150 has good thermal and electrical conductivity. More than 400 varieties of these copper alloys are available, but C18150 is highly preferred since it has high strength and wear resistance at elevated temperatures. C18150 is used extensively for cap-style resistance welding electrodes. It can provide less sticking and resist deformation for much longer than its copper-chrome counterpart in some specific situations.

The chemical composition of C18150 is 1% chromium, 98.85% copper, and 0.15% zirconium. The addition of Zirconium to chromium copper improves creep resistance at high operating temperatures and reduces sticking of electrodes to the work during spot welding of galvanized or coated materials. The physical copper properties of C18150 include a density of 8.89 grams per cubic centimeter.
