A bronze with beryllium as the main alloy component and without tin. It contains 1.7-2.5% beryllium and a small amount of nickel, chromium, titanium and other elements. After quenching and aging treatment, the strength limit can reach 1250-1500MPa, which is close to the level of medium-strength steel. In the quenched state, the plasticity is very good and can be processed into various semi-finished products. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance. It also has good corrosion resistance, thermal conductivity and electrical conductivity. It does not produce sparks when impacted. It is widely used as important elastic components and wear-resistant parts. And explosion-proof tools, etc.
Applied to Welding arms, welding guns and spot welding materials on large mechanical welding equipment such as automobiles and ships
