Grade 23 Titanium/Aluminum/Vanadium Alloy Foil (Light Tight) (Ti90/Al 6/V4)

Grade 23 Titanium/Aluminum/Vanadium Alloy Foil (Light Tight) (Ti90/Al6/V4) is suited for laboratory applications requiring low light transmission, biocompatibility, and mechanical reliability. Its light-blocking properties support optical shielding in photonic setups, while the alloy’s low oxygen content and fine microstructure enable consistent performance in biomedical scaffolding, fatigue testing, and surface engineering studies. Common uses include foil-based components in vacuum chambers, ion beam systems, and thin-film deposition platforms. The foil is also used in microfabrication workflows where corrosion resistance and dimensional stability under thermal and mechanical stress are required.
