Embodiment Construction

[0016] To further remind the present invention, the following is attached figure 1 , 2 , 3, 4, and 5 are explained in detail.

[0017] The silver / copper / iron composite strip produced by the present invention actually has a four-layer structure. From top to bottom, the first layer is silver metal oxide tape 1, and the second layer is a thinner pure silver tape 2 transition layer. , The third layer is copper strip 3, and the fourth layer is iron strip 4. Wherein, the silver metal oxide tape 1 is a tape made of silver metal oxide, and the silver metal oxide includes silver tin oxide indium AgSno2 ino3, silver tin oxide AgSnO2, silver cadmium oxide AgCdO, etc. The copper strip 3 is copper or copper alloy strip, and the process is as follows:

[0018] A. First, clean the surfaces of the silver strip 2 and the silver metal oxide strip 1 to remove the oil and oxides on the surface, and then send the silver strip 2 and the silver metal oxide strip 1 to the hot rolling mill for hot rollin...

Abstract

This invention relates to compound materials technique field to process electricity probe and especially to one silver and copper and iron compound process method, which comprises the following steps: firstly grinding the silver metal oxidation and one film of pure silver materials for combination; then grinding the copper band and iron band to process this invention silver, copper and iron compound band.

Description

Technical field: [0001] The invention relates to the technical field of composite strips for preparing electrical contacts, in particular to a processing technology of silver / copper / iron composite strips. Background technique: [0002] The electrical contact is the contact element of electrical switches, thermostats and other instruments. It is mainly responsible for making and breaking current. It has a decisive effect on the safe operation of electrical appliances. Among the electrical contact materials, silver metal oxide ( Materials such as silver tin oxide (AgSnO2, silver cadmium oxide (AgCdO, etc.)) are widely used in low-voltage electrical appliances due to their good electrical wear resistance, welding resistance and conductivity. With the widespread application of electronic products, the demand for electrical contacts is also increasing. At present, there are electrical contacts on bimetals made of silver and copper. However, the welding of silver, copper and other mate...
