QBe1.7铍青铜

QBe1.7为含有少量镍、钛的铍青铜。具有和QBe2相近的特性，其优点是：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。制作各种重要用途弹簧、精密仪表的弹性元件、敏感元件以及承受高变向载荷的弹性元件，可代替QBe2和QBe2.15等牌号的铍青铜。

QBe1.7化学成分：

 　　铝(Al)≤0.15,                                                       
 　　铁(Fe)≤0.15,                                                       
 　　镍(Ni)0.2～0.4,                                                       
 　　硅(Si)≤0.15,                                                       
 　　铅(Pb)≤0.005,                                                       
 　　铜(Cu)余量,                                                       
 　　钛(Ti)0.10～0.25,                                                       
 　　铍(Be)1.60～1.85,                                                       
 　　杂质总和%≤0.5
