Beryllium copper is a copper alloy with beryllium as the main alloying element, also known as beryllium bronze. It is an advanced elastomeric material with the best performance among copper alloys, and its strength can be close to that of medium-strength steel.

Beryllium bronze is a supersaturated solid solution copper-based alloy, is the mechanical properties, physical properties, chemical properties and corrosion resistance of a good combination of non-ferrous alloys, after solid solution and aging treatment, with a high strength limit, elasticity limit, yield limit and fatigue limit as high as the special steel, but also has a high degree of electrical conductivity, thermal conductivity, widely used in the manufacture of various types of moulds and moulds, replacing the production of steel, high-precision, complex shape moulds, welding electrode materials, pressing and pressing materials. Widely used in the manufacture of various types of mould inserts, alternative steel production of high-precision, complex shape of the mould, welding electrode materials, die-casting machines, injection moulding machine punches, wear-resistant and corrosion-resistant work.

Beryllium copper tape is used in micro-motor brushes, mobile phones, batteries and other products, is an important industrial material indispensable to the construction of the national economy.
