beryllium copper,beryllium cobalt copper,beryllium nickel copper

beryllium copperBeryllium cobalt copper is that metal copper adds metal beryllium and metal cobalt alloying products. It is a supersaturated solid solution of copper base alloy and non-ferrous alloy of with good mechanical properties, physical properties, chemical properties and corrosion resistance.

Through vacuum casting – hot forging – solid solution process – cold forging, heat treatment and other production process, we can produce high conductivity, high thermal conductivity, high hardness, wear resistance, creep resistance and corrosion resistance alloy products.
