Characteristics of the supply and application QBe1.7 bronze bronze

Details: Material Name: QBe1.7 bronze

Standard: (GB / T 5231-2001)

Features and Scope:

as containing a small amount of nickel, titanium bronze. With similar characteristics and QBe2, but its advantages are: small elastic hysteresis, fatigue, high strength, flexibility and stability when the temperature changes, the performance of the aging temperature sensitivity is small, less expensive, but lower strength and hardness than QBe2 little.
