Tantalum/Tungsten Alloy Foil (Light Tight) (Ta90/W 10)

Formula: Ta 90/W 10
Form: Foil (Light Tight)
Material: Tantalum/Tungsten Alloy
Commodity: Alloys
Light Tight: Light Tight
Tantalum/Tungsten Alloy Foil (Light Tight) (Ta90/W 10) is a metallic foil from Goodfellow's range of foils. This alloy foil combines the corrosion resistance and high density of tantalum with the high hardness and strength of tungsten. With a density of 16.6 g/cm3, it provides excellent shielding against x-rays. Applications of this light-tight foil include radiation shielding for medical and scientific instruments and vibration damping in high-precision equipment. The tantalum also imparts chemical inertness for use in corrosive environments.
