Silver Tungsten products

1.These contact materials possess a very high resistance against electric wear and contact welding. 2.High quality

 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 resistance

I  Produced powder metallurgically in single pressed technics, subsequently infiltrated with Ag in liquid phase.

II  The lower side of the contact tips is shaped and infiltrated with a certain excess of Ag.

III  The lower side can be additionally provided with a layer of a brazing alloy  (e.g. L-Ag15P).

V Processing in the shape of tips.
