铍铜

铍铜是一种过饱和固溶铜基合金，是机械性能、物理性能、化学性能及抗蚀性能良好结合的有色合金。 经 固 溶和时效处理后，具有与特殊钢相当的高强度极限、弹性强度、屈服极限和疲劳极限，同时又具有高的导电率、导热率、高硬度和耐磨性、高的蠕变抗力及耐蚀性能。主要用于电阻焊机中各类焊接电极、各类模具镶嵌(替代钢材)、注塑机冲头等耐磨耐高温工件.Beryllium copper is a kind of supersaturated solid solition copper-based alloy,a non-ferrous alloy with well-.combined mechanical property.physical property,chemical property and corrosion resistance.After solid solutiorand agingtreatment.it boasts high strength.elastic strength.vield strength and fatigue strength ,comparable withthose of special steel,as well as high electrical and heat conductivity,high bardness and wearability.high creepresistance and corrosion resistance lt is mainly applied to workina piece with hiah wearability and biah temperatureresistance.such as various welding electrodes for resitance welder,various mould studded piece(substitute ofsteel)punch head of plastic injecting machine.
