Copper Tungsten Rod

The copper tungsten round rod is ground to achieve the precise shape and size, meets American Welding Society RWMA Class 10 specifications, and has a precision tolerance. Copper tungsten provides high wear resistance, electrical and thermal conductivity, and corrosion resistance.

Copper tungsten is a high-strength composite of two metals: copper and tungsten. It combines the benefits of conductivity of copper with the heat and wear resistance of tungsten.

1, Diameter: 1.5-100.0mm
2, Length: 50-1000mm
3, Density: 12.60-17.05 g/cm3
4, Composition: W 55-90%, Cu 10-45%
5, Surface: Sintering surface, Forged surface, Ground surface

Tensile strength, used to indicate the material's overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation.

Copper tungsten Alloy (WCu) is the composite of tungsten and copper which own excellent performance of tungsten and copper. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and aviation.

Copper Tungsten Superior Wear-Resistance

Copper–tungsten (tungsten–copper, CuW, or WCu) alloy 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 instead of a true alloy.
Tungsten alone is a very brittle metal with a high melting point, however the combination of copper and tungsten delivers a relatively hard material with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
Chinatungsten offers copper tungsten in round bars, square bars and flat bars with standard sizes available for immediate shipment or taylor-made sizes manufactured to order.

CUW70 tungsten copper

CUW70 tungsten copper    Cu: W = 30:70 optimum discharge electrode

Tungsten is the preferred metal electrode material. Its strength, density, hardness is high, close to the melting point 3400 ℃, so the EDM process, the tungsten electrode actual loss is small.

But for pure tungsten electrode has two difficulties: a difficult process 2 expensive.

So take advantage of the plasticity of copper, high conductivity, etc., made ​​of composite materials, electrode treasures became - tungsten copper electrode.

Features: · Good breaking arc good thermal conductivity properties · · · High temperature thermal expansion does not soften

Advanced EDM electrodes:

For tungsten steel, high carbon steel, carbide, hardened tool steel using ordinary working electrode loss, low precision, slow processing shortcomings, the use of high conductivity copper tungsten, high melting point, thermal expansion characteristics, improve processing speed, accuracy.
