Description
AWS A5.16 Titanium ErTi-7 Welding Wire is a titanium alloy wire designed for high-quality welding applications. It is available on spools, cut to TIG rod length, or full bar length. These wires are widely used in chemical processing, anodising, pressure vessels, and aerospace or marine applications where high corrosion resistance and strength are required.
ErTi-7 welding wire is composed of approximately 90% titanium, 6% aluminium, and 4% vanadium, offering excellent corrosion and oxidation resistance. It is non-magnetic and suitable for welding in sensitive environments. The coiled wire has a high melting point and can be easily formed or shaped.
