Tungsten/Copper Alloy Foil (W 72/Cu28)

Formula: W 72/Cu 28
Form: Foil/Film/Sheet
Material: Tungsten/Copper Alloy
Commodity: Alloys
Thickness: 3.15mm
Tungsten/Copper Alloy Foil (W 72/Cu28) is a foil from Goodfellow's range of Tungsten/Copper alloy products. This alloy combines the high density and strength of tungsten with the ductility and thermal conductivity of copper. The foil has a density around 16.6 g/cm3 and retains good ductility compared to pure tungsten. Potential applications include radiation shielding, counterweights, and thermal management components. The alloy foil allows designers to take advantage of tungsten's useful properties while improving machinability and formability.
