It is a high-grade elastic material with excellent performance in copper alloys. It has high strength, elasticity, hardness, fatigue strength, small elastic lag, corrosion resistance, wear resistance, cold resistance, high electrical conductivity, non-magnetic, and no sparks when impacted. series of excellent physical,
 
Chemical and mechanical functions.
Chemical composition (mass fraction)%:
Be-0.38-0.4 Ni 2.4-2.8.
Beryllium bronze is a heat treatment strengthened alloy.
Beryllium bronze is mainly used for explosion-proof tools, various molds, bearings, bearing bushes, bushings, gears and various electrodes.
Oxides and dusts of beryllium are harmful to human body, so attention should be paid to protection during production and use.
 
Beryllium copper is an alloy with outstanding mechanical, physical and chemical comprehensive functions. After quenching and tempering, it has high strength, elasticity, wear resistance, fatigue resistance and heat resistance. At the same time, beryllium copper also has high electrical conductivity. High thermal conductivity, cold resistance and non-magnetic, no sparks on impact, easy to weld and braze, excellent corrosion resistance in atmosphere, fresh water and sea water. Corrosion resistance rate of beryllium copper alloy in seawater: (1.1-1.4)×10-2mm/year. Corrosion depth: (10.9-13.8)×10-3mm/year. After corrosion, the strength and elongation remain unchanged, so it can be maintained in water for more than 40 years, and it is an irreplaceable material for submarine cable repeater structures. In sulfuric acid medium: in sulfuric acid with a concentration of less than 80% (room temperature), the annual corrosion depth is 0.0012-0.1175mm, and the corrosion is slightly accelerated when the concentration is greater than 80%.
