Tantalum/Tungsten Alloy Foil (Light Tight) (Ta95/W5)

Tantalum Tungsten Alloy Foil Light Tight (Ta95/W5) delivers exceptional corrosion resistance, high tensile strength, and stability at extreme temperatures in a thin, fully opaque sheet free of pinholes, ensuring complete light blockage. This configuration is vital for high-vacuum barriers, thermal shielding layers, and precision optical system components exposed to aggressive environments. Industries such as aerospace, defense, and semiconductor manufacturing employ it in light-tight radiation shielding, sputtering targets for advanced coatings, and thermal management barriers in sensitive equipment. In research, it supports optical isolation experiments, thin-film deposition studies, and microelectronic fabrication requiring both opacity and extreme-environment performance. The fusion of tantalum’s inertness with tungsten’s reinforcement, combined with its light-tight form, makes it indispensable in high-specification engineering and scientific setups.
