Grade 5 Titanium/Aluminum/Vanadium Alloy Foil (Light Tight) (Ti90/Al 6/V 4)

Grade 5 Titanium/Aluminum/Vanadium Alloy Foil (Light Tight) (Ti90/Al6/V4) is ideal for applications requiring low light transmission, high strength-to-weight ratio, and chemical compatibility. Its light-tight properties support optical sensor isolation, while its mechanical durability suits vacuum chamber linings, hydrogen storage interfaces, and fatigue testing under cyclic loads. The alloy’s corrosion resistance and thermal stability make it suitable for laboratory surface treatment studies, ion beam setups, and thin-film sputtering. Commonly used in aerospace and nuclear research, it serves as a structural barrier or mounting substrate in controlled environments where consistent material behavior is essential.
