Formula: Ta 97.5/W 2.5
Form: Foil/Film/Sheet
Material: Tantalum/Tungsten Alloy
Commodity: Alloys
Temper:
As Rolled
Tantalum/Tungsten Alloy Foil (Ta97.5/W 2.5) is a foil product offered within Goodfellow's range of tantalum and tungsten metal alloy foils. This alloy combines the corrosion resistance and high melting point of tantalum with the high hardness and strength of tungsten. Potential applications include high-temperature furnace components, erosion shields, and sputtering targets. The tantalum imparts ductility while the tungsten contributes wear resistance. With its optimized balance of properties, this foil is suitable for demanding applications in corrosive and high-heat environments.
