Tungsten Copper Alloy Electrode

Our molybdenum electrodes are formed by pressing and then forging to various types after sintering with medium frequency furnace and then turning,rolling,planning and milling. Our company can also offer different kinds of molybdenum electrodes as your requirements. Our company have produced this kind of molybdenum electrode for several decades. And we will spare no effort to the improvement of the electrodes’ performance. With the excellent characteristics of high strength, resistant to oxidation under high temperature, long life, well corrosion resistance and difficult to stain glass. These high purity molybdenum electrodes have been widely used in many fields such as daily use glass, optical glass, insulation material and glass fiber,and received good reputes.

The tungsten copper alloy combines the properties of both the tungsten metals and the copper. And then resulting in a material that is heat-resistant, ablation-resistant, highly thermally, electrically conductive and easy to machine.

Parts are made from the tungsten copper alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

Commonly used copper tungsten alloy contains 10 to 50 wt % of the copper, the remaining portion being mostly tungsten.
The typical properties of the alloy depends on their composition. The alloy with less wt. % of copper has higher density, higher hardness and higher resistivity. The typical density of CuW90 alloy, with 10% of copper, is 16.75g/cm3 and 11.85g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.
