AMS 4900 Grade 1 (UNS R50250) titanium wire is an aerospace-grade commercially pure titanium wire. It meets the AMS 4900 specification and is classified as an alpha-phase titanium alloy. Unlike alpha-beta alloys such as TC4 or beta alloys like TB13, Grade 1 maintains a single-phase alpha structure at room temperature. This unique microstructure provides: excellent ductility,superior corrosion resistance, high purity,etc . With strictly controlled impurities (H ≤ 0.015%, O ≤ 0.18%), Grade 1 wire is widely used in aircraft airframe structures, hydraulic tubing, corrosion-resistant fasteners, and non-critical structural components where formability and corrosion resistance are essential.

AMS 4901 Grade 2 (UNS R50400) titanium wire is an aerospace-grade commercially pure titanium wire. It meets the AMS 4901 specification and is classified as an alpha-phase titanium alloy. Grade 2 offers higher strength than Grade 1 while retaining excellent ductility and weldability. This unique combination provides: Balanced strength and ductility – Higher strength than Grade 1, better formability than Grade 4 Superior corrosion resistance – Outstanding performance in seawater, salt spray, and chemical environments Excellent weldability – Ideal filler wire for titanium structures With strictly controlled impurities (H ≤ 0.015%, O ≤ 0.25%), Grade 2 wire is widely used in aircraft airframe structures, hydraulic tubing, corrosion-resistant fasteners, welding wire, and general aerospace components where reliability and corrosion resistance are critical.
