大口径铍铜管QBe1.7铍青铜 挤压铜管QBe1.7
High beryllium copper for the domestic most the high grade mould beryllium copper, containing beryllium by around 2%, with high strength, high hardness, electrical conductivity, high elasticity, wear resistance, fatigue resistance, corrosion resistance and low elastic hysteresis, etc. Details: material name: QBe1.7 beryllium bronze standard (GB/T 5231-5231) QBe1.7 beryllium bronze characteristics and scope of application: to contain a small amount of nickel, titanium, beryllium bronze. And QBe2 similar characteristics, but its advantage: small elastic hysteresis, high fatigue strength and the elastic stability when temperature changes, the performance sensitivity to the aging temperature change is small, price is low, and the strength and hardness than QBe2 down little.
