Premium Composite Materials
Resistance Welding Electrodes – Heat Sinks – Electrical Contacts – EDM & ECM Electrodes
T & D Materials is an OEM copper tungsten manufacturer and supplier of premium composite materials. Our refractory metal composite materials consist of a combination of tungsten or tungsten carbide and copper or silver. Our manufacturing process is to press the refractory tungsten or tungsten carbide, sinter the pressed compact at a high temperature and infiltrate with copper or silver. As a copper tungsten manufacturer, production is done in a highly controlled environment with ideal conditions. The result is a relatively hard material with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
The mechanical and physical properties of copper tungsten composite materials vary with composition. The thermal and electrical conductivity increase with the amount of copper and silver, while the hardness, strength, and resistance to mechanical wear increase with the amount of tungsten or tungsten carbide. The application determines the best choice of material.
