QBe2/C1720

Beryllium Copper

材料特性1: 锡磷青铜是由青铜(铜锡合金)添加脱氧剂，磷(P)含量0.03～0.35%及其它微量元素如Fe、Zn等組成。

锡磷青铜系列从低锡(Sn4%)到高锡(Sn8%)合金均可生产。具有良好的延展性、深冲性、较高的强度、硬度等优良的综合性能，多用于电子电气设备弹性材料、集成电路引线框架材料、电子，电气用弹簧，开关，接插件，引线框架，连接器，端子，振动片等。

Material Notes:

Good to excellent corrosion resistance. Excellent cold workability; good hot formability. Commonly fabricated by blanking, forming and bending, turning, drilling, tapping.

Applications:springs, flexible metal hose, Bourdon tubing, bellows, clips, washers, retaining rings, and other parts subject to severe forming conditions but require high strength, anelasticity, and fatigue and creep resistance; in parts that require high strength or wear resistance along with good electrical conductivity and/or magnetic characteristics such as navigational instruments, non-sparking safety tools, firing pins, bushings, valves, pumps, shafts, and rolling mill parts.
