C18150 Chromium Zirconium Copper - RWMA Class 2
MasterSource offers a complete line of Copper Alloy C18150 CrZi inventory as noted below.
Copper Alloy UNS C18150
RWMA DESCRIPTION
A specially heat treated chromium-zirconium copper alloy that
meets the minimum electrical and hardness specifications of
Class 2 alloys. Should be used in heat-treated condition.
RWMA GENERAL USE
This materials is stronger than Class 1 materials, have slightly
lower conductivity. They are 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.
ADDITIONAL INFORMATION
Zirconium addition to chromium copper improves creep resistance
at high operating temperatures and reportedly reduces sticking
of electrodes to the work during spot welding of galvanized
materials. C18150 is specified mainly for electrode application.
