Silver Characteristics And Performance of the Tungsten Electrode

Binary alloy of silver and tungsten , whether in liquid or in solid, silver and tungsten are immiscible . There AgW30, AgW60, AgW80 and AgW90 so on. Hardness high arc erosion resistance , anti- adhesion and anti- fusion welding ability. Manufactured by powder metallurgy . More than 60% tungsten alloy production of multi-use impregnated . Used for low-voltage power switch, crane switch, locomotive switch , high current switching pre- contact, as well as heavy-duty relays, air circuit breakers. Cobalt can be added to improve the wettability of silver tungsten , reduce the contact resistance .

Silver and tungsten sintered products , higher conductivity than copper tungsten , as mainly suitable for resistance welding electrodes require high antioxidant work environment . As EDM electrodes of the ordinary copper electrode when the finish is difficult to achieve , so that the abrasive to achieve a very high precision.

AGW-70 silver tungsten electrode materials, and mainly used in welding materials ; such as : low-voltage automatic switch, high voltage circuit breakers and protection switch and so on.

Need for silver tungsten electrodes , usually difficult to machine tool processing equipment and high- quality finish electrode, the electrode repair ordinary copper electrode to achieve the best finish , making the mold to achieve very high accuracy.
