Abstract

The invention relates to the technical field of electrical contact materials, in particular to a copper copying silver material and a method for making the alloy-copper embedded copying silver material. The alloy-copper embedded copying silver material of an automobile electric appliance comprises a brass plate substrate; a positioning groove is arranged on the brass plate substrate; and a silver bar is arranged on the positioning groove and is fixedly melted with the brass plate substrate into a whole. The method for making the alloy-copper embedded copying silver material of the automobile electric appliance comprises the following steps of: 1, digging the positioning groove; 2, welding; 3, sintering; 4, pre-cold rolling; 5, annealing; 6, finely cold rolling; 7, rolling and shearing; and 8, performing surface treatment. The alloy-copper embedded copying silver material, which is produced by the method of the automobile electric appliance has the advantages of high electric conduction performance, good heat conduction performance, high corrosion resistance, strong fusion welding resistance and the like; a contact bridge and a contact are connected into a whole, so the material can be used in frequently-acted automobile appliances, particularly frequency-acted electric appliances such as automobile brake lamp switches and automobile window switches.

Description

technical field [0001] The invention relates to the technical field of electrical contact materials, in particular to a copper-silver compound material and a manufacturing method. Background technique [0002] The contact bridge is usually used in various contactors, and the contact bridge is provided with contacts. The electrical contact on the contact is the contact element of the electrical switch. It is mainly responsible for the task of connecting and disconnecting the circuit, and connecting and disconnecting the load current. The electrical contact and the arc extinguishing system are the heart of the electrical switch. The electrical switch The safety, reliability and opening and closing characteristics of the contactor depend largely on the physical properties of the electrical contact material and its electrical characteristics. Therefore, the performance of electrical contact materials directly affects the reliable operation of electrical switches and related ele...
