补充资料:贵金属及其合金复合触点
分子式:
CAS号:

性质: 贵金属及其合金为复层,以铜为基体的双金属复合触点。节约贵金属、降低成本,而又不影响使用性能。有Ag/Cu、AgAul0/Cu、AgCdO12/Cu、AgCe0.5 /Cu、AgNi0.15/Cu、AgNil0/Cu和AgPb20/Cu等。复合触点的复层维氏硬度分别为490~800MPa,500~800MPa,600~760MPa,600~1100MPa,600~800MPa,650~850MPa和700~1200MPa。由贵金属(或其合金)丝与铜丝经复合铆钉机加工成铆钉。AgCdO12和AgNil0丝材是用粉冶-压力加工法制造;AgCdO12还可用内氧化-粉冶法制造。其他合金丝则用一般压力加工法制取。主要用在低压电器、家用电器、仪器仪表中做中小负荷的开关、继电器的电触点。
