Tungsten Copper Rod Description

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 Rod Picture

Tungsten copper rod is a kind of composite material, which is manufactured by high-purity tungsten powder and high conductivity copper powder with the production process of isostatic pressing, sintering temperature and copper infiltrated.

Tungsten copper rod properties include breaking arc performance, good thermal conductivity, low thermal expansion, in high temperature will not soften, high strength, high density and high hardness.

Tungsten copper rod is mainly used in resistance welding electrodes, EDM electrodes, high-voltage discharge electrodes and electronic packaging materials.

Tungsten Copper Spring Contact

Tungsten copper spring contact is suitable for using the circuit up to the rated voltage 660V AC 50HZ or 60HZ, rated current up to 95A, for making, breaking, frequently starting and controlling the AC motor. Combined with the auxiliary contact block, timer delay and machine interlocking device etc. it becomes the delay contactor, mechanical interlocking contactor, star-delta starter. It is combined into the electromagnetic starter.

Tungsten Copper Spring Contact Picture

On account of their excellent properties, tungsten copper spring contact materials have found a wide field of applications. Tungsten copper spring contact is used successfully with high tungsten content as burn-off contacts for large low-voltage circuit breakers and with lower contents as contacts carrying a steady line current for molded case circuit breakers and in various protective circuit breakers. These tungsten copper spring contact are also used in high current contactor where resistance to contact welding and arc erosion are required. 

The copper and tungsten composite group combines the high thermal and electrical conductivity of copper with the high erosion resistance of the high melting tungsten. These materials are also characterized by their high strength and their resistance to welding or sticking. They are principally made by infiltration and the nominal copper content varies from 10-50%. By increasing the amount of tungsten, the hardness and welding is reduced. This composite group of alloys is specially preferred for use in air.

Tungsten Copper Iron Composite Electrode

Tungsten Copper Iron Composite Electrode Picture

Tungsten copper iron composite electrode also called tungsten copper petiole electrode. One end of the material is tungsten copper alloy, the other end is a relatively high tensile strength steel. Tungsten copper with iron composite is developed in response to customer requirements, a new process technology, using a complex method of manufacturing the pressure. Combined with the end face of tungsten, copper and iron close no holes, the overall low contact resistance, and high tensile strength. Tungsten copper composite electrode material is copper, steel two materials by explosive welding composite, combined with high strength, good electrical conductivity, direct sawing, milling and grinding. In the discharge machining precision parts IC, which is a good overall performance copper electrode can not be replaced, to improve the processing accuracy of parts and reduce overall costs is the most important feature of this material. This material has been widely used in foreign countries, our company can be customized with different ways of complex products according to customer requirements.
