Tungsten Copper Spring Contacts

Tungsten Copper Spring Contacts Picture

Tungsten copper spring contacts with excellent resistance arc burning and welding resistance, breaking arc performance, good thermal conductivity, thermal expansion, high temperature does not soften, high strength, high density, high hardness and other characteristics. It has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At a temperature above 3000 ℃, copper alloy is liquefied evaporated absorbs heat, reduces surface temperature, so these materials are also referred to as metal materials sweating.

Tungsten copper spring contacts are made by powder metallurgy method high pressure contacts of different shapes. Is the use of high-purity tungsten copper contact of tungsten metal powder excellent characteristics and plasticity, high conductivity copper powder of high purity, etc., by isocratic pressing, high temperature sintering, melting refined copper infiltration process of composite materials.

Tungsten copper spring contacts are widely used as high pressure, ultra-hydraulic switch contacts and circuit breakers, protection ring for electric upsetting anvil block material, conductive Tsui automatic submerged arc welding, plasma cutting machine nozzles, welding, welding of welding head, seam welding wheels, electrodes and spark electrode sealing gas Mao point, spot welding, butt welding materials.

Tungsten Copper Brick

Tungsten copper brick (tungsten-copper, Cu-W, or W-Cu) is a pseudo alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the tungsten copper alloy brick material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure of tungsten copper brick is therefore rather a metal matrix composite than a true alloy.

Tungsten Copper Brick Picture

Tungsten copper brick combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.Tungsten copper brick offered by us is high quality.

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

Chinatungsten Online provides tungsten copper alloy brick composites to be used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-powered electronic devices. With the thermal advantages of tungsten copper brick with the very low expansion characteristics of tungsten, tungsten copper brick has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make tungsten copper brick an excellent choice even for extremely dense circuits. Tungsten copper brick can be widely used in many fields, we can provide different sizes of tungsten copper brick according to your requirements.

With the thermal advantages of copper with the very low expansion characteristics of tungsten, tungsten copper has properties similar to those of silicone carbide, aluminum oxide, and beryllium oxide. The thermal conductivity and low expansion also make tungsten copper alloy an excellent choice even for extremely dense  

The CuW75 tungsten copper alloy is used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-power electronic devices. As a tungsten copper material, it's a composite, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.

Copper Tungsten is one of the most popular refractory metal based heat base materials offered today. At China Tungsten we can offer all kinds of tungsten copper heat base as the customer's requirements.

Tungsten copper heat base also called tungsten copper heat sink. Tungsten copper heat base is a heat base which is made of tungsten copper alloy. A heat base is a term for a component or assembly that transfers heat generated within a solid material to a fluid medium, such as air or a liquid. Examples of heat bases are the heat exchangers used in refrigeration and air conditioning systems and the radiator (also a heat exchanger) in a car. Heat bases also help to cool electronic and optoelectronic devices, such as higher-power lasers and light emitting diodes (LEDs).

Tungsten Copper Welding Electrode

At the end of February, our client inform us our tungsten copper welding electrode which have been delivery to his company at the end of January are not suitable for his application.

He inform us maybe the material are wrong, the real material he have been used are not tungsten copper, so he send us his product. We have got his product on Mar.3, 2018. As we could not testing the material’s content, so we have sent the products to Beijing to test. Now, the the test result reports that the material is not tungsten copper, it is pure tungsten.

We inform the client we are also able provide pure tungsten, so the client requires us provide the quotation about pure tungsten to him. Now, the price are under calculating, we will provide the price to him soon. This is the tungsten copper welding electrode provided by us:

New Order for Tungsten Copper Plate

Last week, we have got our old client’s new order for tungsten copper plate, and this client is from malaysia, he is a good client.
Last order, he have order some rods and some plates, he said our products are excellent. And they wook well, so he want to order more this time.
The following photos are the products he had ordered:

Tungsten  Copper Plate Picture

Tungsten copper plate is a combination of tungsten and copper. 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, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.

The application of tungsten copper plate are as following:
1. Resistance Welding Electrode
2. Electric Spark Electrode
3. High-voltage Discharge Tube Electrode
4. Electrical Seal Material
