Silver Tungsten

Application – Silver Tungsten is produced in exactly the same way as Copper Tungsten, but substituting copper with pure silver. The very high cost of this material usually dictates the production of very small bars. Silver Tungsten has the same good and bad points as Copper Tungsten. Its overall advantage is the high conductivity of silver which means that the smallest current can be carried, giving negligible spark gap and fine surface finish. It is used in the United Staes on work requiring the highest possible accuracy.
