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 tungsten copper alloy. The alloy is also made into sheet metal, tubing and plate metal. Tungsten copper alloy is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches.

We specialize in manufacturing and offering tungsten related products for more than 20 years, and can provide tungsten copper 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.
