C15000 Zirconium Copper - RWMA Class I

MasterSource offers a complete line of Copper Alloy C15000 Zr inventory as noted below.

Copper Alloy UNS C15000

A specially heat treated zirconium copper alloy that meets the minimum electrical conductivity and hardness specifications of class 1 alloy.

Electrodes for welding aluminum alloys, magnesium alloys, coated materials, brass and bronzes. Can be used for both spot and seam welding.

A small addition of Zr to copper improves resistance to softening and resists deformation at high temperatures where normal copper would soften rapidly. Zirconium Copper is used as a class 1 electrode material to minimize sticking when resistance spot welding galvanized materials. Zirconium Copper is also used in many high temperature applications i.e. aerospace, power generation, etc.
