ERTi-7

Description
ERTi-7, Commercially Pure Titanium with good balance of strength, formability and weldability. It can equivalent to: Oxford Alloy Ti-7.

Applications
Titanium grade 7 has outstanding corrosion resistance and useful strength at low density. A small addition of palladium has been made to this alloy for a substantial increase in corrosion resistance. Typical application include reactor autoclaves, piping and fittings, valves, heat exchangers and condensers
