 The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
 figure 1 One embodiment of the silver-nickel electrical contact manufacturing process of the present invention is shown.
 Silver-nickel contact material is an environmentally friendly material developed in recent years. It has good welding resistance and arc erosion resistance, which can meet the requirements of high reliability and long life in electrical operation. With the enhancement of people's awareness of environmental protection, it will be the general trend to replace AgCdO electrical contact materials with silver-nickel electrical contact materials in the fields of low-power thermostats and relays.
 There are mainly three mature processes for the production of silver-nickel electrical contact materials: powder mixing, ball milling, and co-precipitation. Among them, the raw materials of silver-nickel contacts ...
