高强铍青铜QBe1.7铜棒 上海供应商批发铍铜
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.
QBe1.7铍青铜特性及适用范围:为含有少量镍、钛的铍青铜。具有和QBe2相近的特性,但其X点:弹性迟滞小、疲劳强度高,温度变化时弹性稳定,性能对时效温度变化的敏感性小、价格较低廉,而强度和硬度比QBe2降低甚少。
