Beryllium copper sheet

Short Description:

Beryllium copper strip　is a bronze whose main alloy component is beryllium　strip. Containing 1.7~2.5% beryllium and a small amount of nickel, chromium, titanium and other elements, after quenching treatment, the strength can reach 1250~1500MPa, close to the level of medium strength steel. In the quenching state plasticity is very good, can be processed into a variety of semi-finished products. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, as well as good corrosion resistance, thermal conductivity and electrical conductivity
