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 containing a small amount of nickel and titanium. It has similar characteristics to QBe2, and its advantages are: small elastic hysteresis, high fatigue strength, stable elasticity when temperature changes, low sensitivity of performance to aging temperature changes, lower price, and lower strength and hardness than QBe2. It has the characteristics of not producing sparks. QBe1.9-0.1 is used to make springs for various important purposes, elastic components of precision instruments, sensitive components and elastic components that are subjected to high changing loads. It can replace beryllium bronze of QBe2 and QBe2.15.
