What is Tungsten Copper Plate

Tungsten copper plate is a composite of tungsten and copper. The coefficient of thermal expansion of the composite can be designed by controlling the content of tungsten, matching that of the materials, such as Ceramics, Semiconductors, Metals, etc. The products are widely application in the fields such as radio frequency, microwave, high power diode packaging and optical communication system.

Tungsten Copper Rod

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 hardnes.

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

Tungsten Copper Spring Contact

Tungsten Copper Spring Contact Picture

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.

On account of their excellent properties, tungsten copper spring contact material has found a wide field of applications. Tungsten copper spring contactss are 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 contactss are also used in high current contactors 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.

What is Tungsten Copper Bar

Tungsten copper bar includes the both properties of tungsten and copper, are widely used on EDM and heat sink. The smallest thickness we are able to provide is 0.1mm, and we are also able to provide the special required for each client.

Tungsten Copper Bar Picture

Tungsten copper bar we provided is seriously obeyed international GB/T8320 producing. Our tungsten copper bars are high density and high conductivity and high hardness. Also, it is the first choice material of mirror spark discharge electrode.

The manufacturing process is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, good electrical and thermal conductivity.

The composition of tungsten copper bar we are able to provide is from 10Cu to 50Cu, or if you have any special required of the composition, you can contact us without delay. Our technical department could research per client's per special required.
