Grade 23 ELI Titanium/Aluminum/Vanadium Alloy Foil (Ti90/Al6/V4)

Grade 23 ELI Titanium/Aluminum/Vanadium Alloy Foil (Ti90/Al6/V4) is optimized for scientific and R&D applications requiring high fatigue strength, biocompatibility, and low interstitial impurity levels. The foil’s uniform microstructure enables consistent performance in ultrasonic fatigue testing, ion beam exposure studies, and precision thin-film applications. It is used as a substrate in biomedical device development, as a structural interface in proton beam experiments, and for sputtering targets in surface engineering. Its stability under thermal cycling and resistance to corrosion make it suitable for vacuum environments, high-purity chambers, and cleanroom-based fabrication processes in materials science, accelerator R&D, and microfabrication.
