beryllium copper is an alloy with good comprehensive mechanical, physical and chemical properties. 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. Resistance, thermal conductivity, cold resistance and non-magnetic, no spark when hit, easy to weld and braze, excellent corrosion resistance in the 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, there is no change in strength and elongation, so it can be maintained in seawater for more than 40 years. It is an irreplaceable material for submarine cable repeater structures. In the sulfuric acid medium: the annual corrosion depth in sulfuric acid (room temperature) less than 80% concentration is 0.0012-0.1175mm, and the corrosion is slightly accelerated if the concentration is more than 80%.
Highly conductive cast beryllium copper alloy with high electrical conductivity and thermal conductivity after heat treatment. Beryllium copper alloy is suitable for manufacturing switch parts, strong contact and similar current-carrying components, making resistance welding clamps, electrode materials and plastic molds. , Inner sleeve of mold for hydroelectric continuous casting machine, etc.
