摘要
针对锡磷青铜偏析倾向严重,国产带材组织、性能一致性差、弹性元件寿命短的问题,发现用C64780合金可以代替锡磷青铜。C64780合金是一种Ni-Si青铜系合金,与锡磷青铜相比,具有相同的密度、熔化温度、疲劳寿命、强度和硬度,更有高的导电/导热性、软化温度和抗应力松弛能力。用C64780合金代替锡磷青铜带材,既可以降低原材料成本和加工成本,同时也可以极大地改善国产锡磷青铜性能差、弹性元件寿命短的问题,提升国产材料的性能。
Due to the problems in the serious segregation tendency and poor strip microstructure,performance uniformity as well as the low service life of elastic components,it is a acceptable choice for C64780 alloy substituted for the phosphor bronze.Compared with the phosphor bronze,C64780 alloy as silicon bronze alloy,is the equivalent in density,melting temperature,fatigue life,strength and hardness,and is superior in resistance stress relaxation and more high conductive/thermal conductivity as well as softening temperature.C64780 alloy can decrease the cost of raw materials and control the processing costs,and greatly improve the problems from the use of the phosphor bronze.
