The composite electrical contact material for making electric elements includes one copper alloy layer and one silver alloy layer on the copper alloy layer. It features the silver alloy layer, which is made of silver alloy containing Zn in 0.10-6.00 wt%, Cu in 0.10-15.00 wt% and Ni in 0.05-2.00 wt%, and covers all or partial surface of the copper alloy layer. The silver alloy has low-melting point, easy-to-volatize and non-toxic Zn, rather than toxic Cd, and thus has excellent electrically conducting and heat conducting performance, high mechanical performance, good environment protecting performance and high arc extinguishing effect and is suitable for use as electrically contacting material.
Description
technical field [0001] The invention relates to a composite material, in particular to an electrical contact composite material used for manufacturing electrical components. Background technique [0002] At present, advanced composite technology is used to firmly composite silver alloys with excellent electrical conductivity and copper alloy materials as a whole, and process them into strips or other profiles to manufacture electrical components, such as commutators, switches and electric plugs for micro motors. pick up etc. This can not only give full play to the excellent electrical and thermal conductivity of silver alloys, but also give full play to the advantages of high mechanical strength of copper alloys, save a lot of precious silver alloys, and reduce production costs. In order to enhance the arc extinguishing effect during the electrical contact process, the existing composite materials add a certain amount of metal cadmium to the silve...
