Alloy material: chromium copper
CuCr Grade：C18200
Alloy material: zirconium copper
CuZr Grade：C15000
Alloy material: chromium zirconium copper
CuCrZr Grade：C18150
These three copper alloy has relatively high intensity and hardness, good conductivity, and thermal conductivity. The hardness, intensity, conductivity and thermal conductivity are remarkable improved after ageing treatment. It has been widely applied in collector, spot welding machine, seam welder, butt welder as high intensity, conductivity fittings.
