铍青铜是机械性能、物理化学性能和抗蚀性良好的一种铜合金,而且是典型的沉淀硬化型合金。它在淬火状态下(固溶状态)具有高的塑性,能拉成管、棒、线和轧成带材,可加工成形状复杂的零件。经淬火时效后又具有良好的综合性能。如很高的强度、硬度、疲劳极限和弹性极限;弹性滞后小,弹性稳定;耐蚀、耐磨、耐寒、无磁性;此外它还保持着铜合金优良的导电导热性,冲击时无火花,常被用作高度精密的弹性元件,而且可作高速、高压、高温工作的耐磨元件如轴承、衬套、齿轮等。皱青铜已成为精密仪器、仪表制造、电子、电器工业上非常重要的金属材料。
Beryllium bronze is a copper alloy with good mechanical properties, physicochemical properties and corrosion resistance, and is a typical precipitation hardened alloy. It is hardened (solid solution state) with high plasticity, can pull into the tube, rod, wire and rolled into the strip, can be processed into complex shape parts. After quenching and aging has a good overall performance. Such as high strength, hardness, fatigue limit and elastic limit; small elastic hysteresis, elastic stability; corrosion resistance, wear resistance, cold resistance, nonmagnetic; in addition, it also maintains the copper alloy excellent electrical and thermal conductivity, Often used as highly precise elastic components, but also for high-speed, high pressure, high temperature work wear-resistant components such as bearings, bushings, gears and so on. Crumpled bronze has become a very important metal material for precision instruments, instrumentation, electronics, and electrical appliances.
