Beryllium nickel copper is an oversaturated solid solution copper-based alloy, a non-ferrous metal that combines excellent mechanical, physical, chemical, and corrosion-resistant properties.

After solution heat treatment and aging, it possesses high ultimate strength, elastic limit, yield limit, and fatigue limit comparable to special steel; it also features high conductivity, thermal conductivity, hardness, wear resistance, 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 punches, and wear and corrosion-resistant workpieces.
