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.

High conductivity, thermal conductivity and high melting point of silver and high hardness, welding resistance, small material transfer, and high burning resistance of tungsten are conbined into silver-tungsten sintering material.Silver tungsten electrical contact will generate mixed oxides, if it is frequently off in the air, under operating current, so that form the the surface film that can increase the contact resistance.
Composition: W 30%-80%, Ag 20%-70%
Density: 11.75-16.10 g/cm3
Under the relative intensity conditions, silver-tungsten performs exceptionally good electrical conductivity and stability in comparison with the super-hard metal such as tungsten-steel etc. it can also keep fine acute angle, it has the better performance than copper-tungsten in aspects of loss.

Silver Copper Welding electrode: Particularly desired for MIG welding of zinc-coated-steel in auto bodies. It is also recommended for Cu-Zn alloy, low-alloy copper, non-alloys and low-alloys steel and cast iron. An ideal material for making auto bodies.
