Silver alloy composed of silver and tungsten, binary alloy of silver and tungsten.
Tungsten silver is a silver alloy composed of silver and tungsten, a binary alloy of silver and tungsten. Used as low-voltage power switches, lifting switches, locomotive switches, pre-contacts of high-current switches, as well as heavy-load relays, air circuit breakers, etc. Adding cobalt can improve the wettability of silver to tungsten and reduce contact resistance.
The produced tungsten-silver alloy conforms to the national standard GB/T8320-2003 and ASTM B631 standard.

Silver tungsten is produced by vacuum infiltration, with excellent performance and stable quality. Because the melting points of tungsten and silver are very different. Like tungsten-copper alloys, silver-tungsten alloys cannot be produced by traditional casting methods. Our process route is powder preparation - pressing - sintering - infiltration - machining. Our company selects high-purity tungsten powder and silver powder, mixes them evenly and puts them into granulation equipment to complete the powder preparation. The professionally customized vacuum sintering furnace ensures that the interior of the silver-tungsten alloy is uniform and free of holes.
Silver tungsten plates and other products are widely used in industrial fields such as electric spark discharge electrodes, resistance welding electrodes, precision probe needles and precision bearings.
