Beryllium nickel copper is an oversaturated solid solution copper-based alloy, a non-ferrous metal with a good combination of mechanical, physical, chemical, and corrosion-resistant properties.

After solution heat treatment and aging, it possesses high strength limits, elastic limits, yield limits, and fatigue limits comparable to special steels; it also features high conductivity, thermal conductivity, hardness, wear resistance, high creep resistance, and corrosion resistance.

Widely used in manufacturing various mold inserts, replacing steel for high-precision, complex-shaped mold welding electrode materials, die casting machines, injection molding punch heads, wear and corrosion-resistant work, etc.
