ERTi-2 (Commercially Pure) Titanium is a TIG, MIG and submerged arc filler metal used for
welding commercial pure titanium alloys commonly found in applications requiring high temperature resistance and resistance to chemical reagents. Although there are four grades of Commercial Pure Titanium filler metals, C.P. Grade 2 (ERTi-2) is the most popular because of its good balance of strength, formability and weldability. The most common applications of ERTi-2 are the aircraft industry, where tensile strength and weight ratios are very critical. Other uses would include cryogenic and petrochemical applications such as chemical process heat exchangers, pressure vessels and piping systems, pulp bleaching systems, electro chemical and chemical storage tanks.
