Beryllium copper is beryllium based alloy element copper alloy, also known as beryllium bronze. It is a kind of high-grade elastic material with good properties in copper alloy. It has high strength, elasticity, hardness, fatigue strength, small elastic lag, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic and many good physical, chemical properties and mechanical properties.

Beryllium copper is mainly used for processing various high-grade elastic components, so it is also one of the preferred materials for making shrapnel.

The processed beryllium-copper elastic sheet has shielding effect (the design engineer of computer and electrical equipment regards beryllium-copper elastic sheet as ideal electromagnetic wave shielding material), high relaxation resistance and excellent wear resistance, conductivity, corrosion resistance, wear resistance, cold resistance, etc.

Beryllium copper shrapnel is used for miniature switches, various shielding chambers, hatches, cabinet doors, covers, printed board inserts, mobile phones, integrated circuit shielding, etc.
