Tungsten copper contacts is an alloy composite of tungsten and copper, which include both excellent properties of tungsten and copper, such as heat resistance, aberration resistance, high density, excellent thermal and electrical conductivity. Tungsten copper contacts are the best suitable material for electrical discharge machining (EDM) applications. It has excellent wear resistance, good metal removal rate and ability to retain good detail....More

Tungsten copper rod is a kind of round rod. The grade of tungsten copper rod include WD10070、WD10075 and WD10080. the choice of tungsten copper content are depend of the application of tungsten copper rod, but if you do not know the detail application of the material, you can choice the content according to GB/T8320-2003. Tungsten copper heat sink owns not only the low expansion of tungsten and high heat conductivity of copper. Its expansion index and heat conductivity can also be changed through changing the content of the materials, which provides convenience to the using of the material. ...More
