Common Specifications of Beryllium Bronze

QBe1.9-0.1 beryllium bronze

QBe1.9-0.1 beryllium bronze is a beryllium bronze containing a small amount of nickel and titanium.

Chinese name: QBe1.9-0.1 beryllium bronze
Advantages: small elastic hysteresis, high fatigue strength

QBe1.9-0.1 is beryllium bronze with a small amount of nickel and titanium. It has characteristics similar to QBe2, and its advantages are: small elastic hysteresis, high fatigue strength, stable elasticity when temperature changes, low sensitivity to aging temperature changes, low price, and less reduction in strength and hardness than QBe2. It does not produce sparks.

QBe1.9-0.1 is used to make various important-purpose springs, elastic components of precision instruments, sensitive components, and elastic components that bear high variable direction loads. It can replace beryllium bronze of QBe2 and QBe2.15.
