Silver tungsten electrode can also be called silver tungsten rod and silver tungsten bar. Silver tungsten electrode is the alloy of tungsten and silver. Silver and tungsten’s mutual solubility is very low, and this has been the reason why silver tungsten electrode can only be made by powder metallurgy and pressing method.
Silver tungsten electrode owns the properties of high hardness, high arc corrosion resistance, and high fusion welding resistance.
Silver tungsten electrode is widely used in high temperature resistance industry, electronics and microelectronics industry, metallurgy industry. The most popular application of silver tungsten electrodes is to be used as switches.
The specification of sliver tungsten electrodes can be clarified by the content of tungsten and silver. There are AgW30, AgW40, AgW50, AgW55, AgW60, AgW65, AgW70, AgW75, AgW80, and AgW85.
