    Beryllium nickel copper is a supersaturated solid solution copper-based alloy, a non-ferrous alloy with a good combination of mechanical properties, physical properties, chemical properties and corrosion resistance. After solid solution and aging treatment, it has high strength limit, elastic limit, yield limit and fatigue limit equivalent to that of special steel. At the same time, it has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance. Widely used in the manufacture of various mold inserts, replacing steel materials with high-precision, complex-shaped mold welding electrode materials, die-casting machines, injection molding machine punches, wear-resistant and corrosion-resistant work, etc. Beryllium nickel copper tape is used in micro-motor brushes, mobile phones, batteries, computer connectors, various switch contacts, springs, clips, washers, diaphragms, membranes and other products.
