Tungsten Copper Rod
Tungsten copper rod has two machining methods: turning and grinding. This depends on the diameter and customer’s requirement of dia. tolerance. If without special request, our tungsten copper rod Dia. tolerance is (0, +0.02) mm. the length tolerance according to the ISO2768 class C.
Our tungsten copper rod has very good physical and mechanical properties. The largest normal diameter size is 200 mm, but we can still customize produce the different size according to the special demanding. Our tungsten copper rod is widely used as EDM electrode, especially for the tungsten carbide EDMing; it also can be used as the resistance welding face insert due to the good hardness and high electrical conductivity.
Tungsten copper rod is consisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are known for good thermal and electrical conductivity, low thermal expansion, and resistance to erosion from arcing. Thus, they are often used as electrical contacts, particularly in high voltage applications. Most sizes and shapes can be supplied with short lead times. We can also manufacture parts from these materials to your specifications.
