1. Beryllium nickel copper is a supersaturated solid solution copper based alloy, which is a non-ferrous alloy with good mechanical, physical, chemical, and corrosion resistance properties.

2. After solid solution and aging treatment, it has elasticity, yield, and fatigue equivalent to special steel; At the same time, it has high conductivity, thermal conductivity, high hardness, and creep resistance.

3. Used for manufacturing various types of mold inserts, replacing steel to produce high-precision and complex shaped mold welding electrode materials, die-casting machines, injection molding machine punches, etc.
