Tungsten copper blocks: they are produced by isostatic pressing, high temperature sintering and copper infiltration process. They can be made into frame heat conducting plates, chip carriers and high-energy electron devices. They have good thermal conductivity and low expansion. Its expansion is equal to the silicon carbide, alumina oxide and beryllium oxide. The good characteristics of tungsten copper blocks made themselves to be the best material for integrated circuits, and they are widely used in various fields. We can produce tungsten copper blocks with different shapes according to customers’ requirements.
