高强度铍青铜【QBe1.7铍铜棒】高铍铍青铜生产
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.
