Composition: Ta 90/W 10
Form: Foil (Light Tight)
Material: Tantalum/Tungsten
Commodity: Alloys
Light Tight:
Light Tight
Tantalum Tungsten Alloy Foil Light Tight (Ta90/W10) offers superior corrosion resistance, elevated strength, and thermal stability in an ultra-thin sheet form free of pinholes, blocking all external light transmission. This structure is ideal for precision shielding, high-vacuum barriers, and thin-film substrate applications in chemically aggressive or high-temperature environments. Industries such as aerospace, semiconductor fabrication, and analytical instrumentation utilize it for radiation shielding layers, sputtering targets, and thermal protection membranes. Research employs this foil in microfabrication experiments, vacuum optics systems, and electrochemical corrosion studies. The combination of light-tight integrity, alloyed mechanical reinforcement, and resistance to thermal and chemical degradation ensures unmatched reliability where both optical opacity and extreme environment performance are critical.
