Material name: QBe2 beryllium bronze
Standard :(GB/T 5231-2001)
Features and scope of application:ASTM A106 Steel Pipes Galvanized Structure Tube
After quenching and tempering, it has high strength. Hardness. Elasticity. Wear resistance. Fatigue limit and heat resistance; It also has high electrical conductivity. Thermal conductivity and cold resistance, non-magnetic, no spark on impact, easy to weld and fiber weld in the atmosphere. Excellent corrosion resistance in fresh and seawater. QBe2 beryllium copper product characteristics: high performance copper alloy, after solution and aging hardening treatment, has high hardness, high wear resistance, high knock resistance, high yield limit and fatigue limit, good corrosion resistance, high conductivity and excellent heat dissipation performance. Easy to process, excellent cooling effect. Beryllium copper applications: used as raw material for high precision electronic, plastic and optical moulds where water is not available, as cooling system for soil parts, cores, punts, hot channel cooling systems, communication preparation equipment, electronic and electrical equipment, instrumentation, aerospace, automotive manufacturing and processing parts.
