A line of silver-tungsten rods.

What is Silver-Tungsten?

Silver-tungsten (tungsten-silver) is similar to copper-tungsten in many ways. Like copper-tungsten, it is a pseudo-alloy, with the silver infiltrated into a matrix of tungsten. The combination of silver and tungsten results in a material sharing the characteristics of both silver and tungsten, while tempering the extremes of both. Silver tungsten is strong, capable of penetrating the toughest materials, and machinable. But above all else, it is conductive. In fact, silver has the greatest conductivity of any known element at temperatures and pressures found on Earth, and silver-tungsten retains much of this conductivity.

Advantages of Silver-Tungsten

The great conductivity of silver combined with the low wear rate of tungsten make silver-tungsten ideal when a fine surface finish is desired. Because of its exceptionally low wear rate, silver-tungsten excels at drilling very deep holes with straight walls, and well-defined corners.

Disadvantages of Silver-Tungsten

Silver-tungsten’s only disadvantage is that it is overkill for many applications. More expensive even than tungsten carbide, silver-tungsten should only be used when absolutely necessary.

Ordering Custom EDM Electrodes

If an electrode in the desired size cannot be found in the parts list below, do not hesitate to contact us. Custom electrodes can be requested conforming to the following standards:

  • Tolerances for electrodes are from +.00mm to -.02mm (+.0000″ to -.0008″).
  • Lengths may be from 100mm to 400mm (4″ to 16″).
  • Electrode Spec Sheet
  • Silver-tungsten comes in alloy mixtures from 74% to 50% tungsten (26% to 50% silver content).
