Tungsten silver alloy
An alloy composed of tungsten and silver has a silver content of 30% to 70%.
The preparation method is the same as that of the tungsten-copper alloy. Compared with tungsten-copper alloys, tungsten-silver alloys have better electrical and thermal conductivity, plasticity and oxidation resistance, while strength and hardness are relatively low, and low lattices are higher. The application of such alloys is similar to that of tungsten-copper alloys, which have been used as nozzle linings for solid rockets. On the electrical switch, tungsten-silver alloy is more used in lower voltage circuit breakers, automatic switches, contact switches, etc., which require good oxidation resistance, higher electrical and thermal conductivity, smaller contact size, and frequent opening and closing operations.
