Copper alloy 18150 is a high-strength copper alloy containing chromium and zirconium that provides exceptional electrical and thermal conductivity along with corrosion resistance and durability. In sheet/plate form, it is commonly used for applications like electrical contacts, resistance welding components, marine hardware, and high-stress parts in aerospace, automotive, and heavy machinery industries where its strength and conductivity are valued. The chromium and zirconium additions give 18150 its ability to resist deformation and sticking when used for welding electrodes.
