Description
Technical Parameters
Basic Definition
Titanium Grade 23 Foil is an ultra-thin, precision-rolled form of the extra low interstitial (ELI) variant of the Ti-6Al-4V α+β titanium alloy.
It is produced by multi‑pass cold rolling with intermediate vacuum annealing to control the grain structure. That is the way to minimize interstitial pickup, and guarantee uniform thickness and flatness. Final surface treatments include pickling, electropolishing, or laser cleaning to meet medical requirements.
