Grade 5 Titanium Wire（Ti-6Al-4V）
Gr5 Titanium Wire is the preferred choice for aerospace, 3D printing, and high-end medical applications. As an α+β titanium alloy, it combines three key advantages: high strength, lightweight, and excellent corrosion resistance. Its specific strength is approximately twice that of 304 stainless steel at the same weight, significantly reducing structural weight.
Chalco Titanium offers Ø0.1 – 6 mm stock, all compliant with ASTM B863 / UNS R56400 / AMS 4928 standards.
