Description

technical field [0001] The invention relates to a beryllium copper alloy and a preparation method thereof. Background technique [0002] Beryllium copper, also known as beryllium bronze, is the "king of elasticity" in copper alloys. After solution aging heat treatment, products with high strength and high conductivity can be obtained. High-strength cast beryllium bronze alloy, after heat treatment, not only has high strength, high hardness but also has the advantages of wear resistance and corrosion resistance, excellent casting performance, beryllium bronze alloy is suitable for manufacturing various molds, explosion-proof safety tools, wear-resistant Components such as cams, gears, worm gears, bearings, etc. High beryllium copper has the characteristics of high strength, high hardness, high conductivity, high elasticity, wear resistance, fatigue resistance, corrosion resistance and small elastic hysteresis, and is mainly used in temperature controllers, mobile phone batte...
