SILVER TUNGSTEN EDM

When most people think electrical discharge machining, they think brass, copper, and maybe tungsten carbide electrodes. These three materials are ideal for the great majority of EDM applications, and it's not often that customers ask for anything else. But sometimes the unique requirements of an EDM job require the unique properties of an exotic material.z... The properties of silver and tungsten preclude creating a true alloy from them. Silver-tungsten is a metal matrix composite, which is made by infiltrating molten silver into a matrix of tungsten... Silver-tungsten electrodes for niche applications requiring a very fine surface finish.
