Tungsten/Copper Alloy Foil (W 80/Cu20)

Formula: W 80/Cu 20
Form: Foil/Film/Sheet
Material: Tungsten/Copper Alloy
Commodity: Alloys
Thickness: 3mm
Tungsten/Copper Alloy Foil (W 80/Cu20) is a high-temperature, high-strength, and electrically-conductive foil within Goodfellow's range of foils. The tungsten provides hardness and strength at elevated temperatures, while the copper improves ductility and electrical conductivity. This alloy combines the high-temperature strength of tungsten with the ductility of copper. Potential applications include electrical contacts and high-temperature structural components requiring oxidation resistance and electrical conductivity. The unique properties of this tungsten-copper alloy make it suitable for niche applications requiring a combination of strength, ductility, conductivity, and high-temperature performance.
