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.
