Tungsten Copper

What Is Tungsten Copper?

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

Copper Tungsten Alloy Powder

Copper tungsten alloy powder is used in injection molds for mold pressing parts as well as extrusion pressing. It is also used as a die lubricant in molds. The alloy is machined in a factory setting to make highly complex and intricate components such as microprocessors. It is also used to make parts of microwave communication systems and other electronic technologies.

Copper Tungsten Alloy Applications

Copper tungsten alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity. Tungsten copper alloy is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made out of WCu alloy. The alloy is also made into sheet metal, tubing and plate metal. WCu alloy is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches.

The Spark Erosion (EDM) process calls for copper tungsten. Usually this process is used with graphite, but tungsten has a high melting point. This allows the CuW electrodes to have a longer service life than the graphite electrodes. This is crucial when the electrodes have been processed with complex machining. Since the electrodes are susceptible to wear the electrodes provide more geometrical accuracy than the other electrodes. These properties also let the rods and tubes manufactured for spark erosion be made smaller in diameter and have a longer length since the material is less likely to chip and warp.

We specialize in manufacturing and offering tungsten related products for more than 20 years, and can provide WCu alloy as bellows:

Copper Tungsten Alloy Electrode

Our copper tungssten alloy electrode is best suitable for EDM machining of those materials.
Advantages: low wear, high contour sharpness,good machinability.
Other types of product: tubes and plates.

Copper Tungsten Alloy Heat Sink

Copper tungsten alloy  is widely used as heat sinks concerning with radiator for car, refrigeration and air conditioning systems, because of its low thermal expansion, heat-resistant, ablate-resistant, excellent thermal and electrical conductivity. WCu heat sinks galvanically plated with Ni or NiAu or electroless Ni plated Semi-finished products: up to 100x100mm with a thickness of 0.5 to 50mm.

Copper Tungsten Alloy Electrical Contacts

Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Our copper tungsten alloy materials are used owing to their unique physical properties.

Tube: Ø5~290 
Special type:





















The electrical and thermal properties of the alloy vary with different proportions. Increase in copper increases the thermal conductivity, which plays a huge part when being used in circuit breakers. Electrical resistivity increases with an increase in the percentage of tungsten present in the alloy, ranging from 3.16 at 55% tungsten to 6.1 when the alloy contains 90% tungsten. An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and 20% copper with an ultimate tensile strength of 663 MPa. After this mixture of copper and tungsten, the ultimate tensile strength then begins to decrease fairly rapidly.
