Gr2 Titanium Foil Description
1. Introduction
Gr2 Titanium Foil is an ultra-thin titanium strip produced through precision rolling from Grade 2 industrial pure titanium ( purity≥ 99.2%), as the most widely used type of industrial pure titanium, it features moderate strength—(higher than Grade 1 but lower than Grade 4)—together with high ductility and excellent corrosion resistance.
Compared with Grade 1 titanium foil, Gr2 Titanium Foil offers higher strength with maintaining excellent formability, delivering better structural support during use without affecting subsequent processing.
