AgW Silver tungsten contact rivets for switches
Electrical contacts factory, more than 12 years manufacture experience, attained ISO9001-2015, work on OEM and ODM projects..
1. Introduction of Silver tungsten electrical contact
Silver Tungsten AgW alloy was used as the nozzle throat lining of solid rockets. In electrical switches, tungsten-silver alloys are more used in lower voltage circuit breakers, automatic switches, contactors, etc., which require good oxidation resistance, higher thermal conductivity, smaller contact size, and frequent opening and closing operations.
2. Application of Silver tungsten electrical contact
Silver Tungsten AgW electrical contact widely used in high-temperature resistant materials, electrical alloys for high-voltage switches, electro-processed electrodes, and microelectronic materials. As parts and components, they are widely used in aerospace, aviation, electronics, power, metallurgy, machinery, sports equipment and other industries etc.
