Silver Tungsten Alloy And Electrode For PCD / Electrical Contact Welding Electrode
Description:
Silver tungsten materials are used in industrial and domestic circuit breaker applications where good weld and erosion resistance is important. Various grades are available: - the higher silver grades have higher conductivity, and the higher tungsten grades have greater erosion and weld resistance.
High contact pressures are required to ensure effective operation if used for frequent high current switching, where mixed oxides of silver tungsten can be formed, giving high contact resistanceSilver tungsten alloys contain between 25-50% silver and are mainly used for electrical contacts—generally heavy-duty devices subject to high current, such as circuit breakers, earth leakage breakers and miniature circuit breakers.
