机械制造用铍青铜【QBe1.9铜棒】厂家X铍铜棒
QBe1.9 beryllium bronze characteristics and scope of application: QBe1.9 beryllium bronze for containing a small amount of nickel, titanium, beryllium bronze. And QBe2 similar characteristics, but its advantage is: elastic hysteresis is small, 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.
