ERTi-2 (Commercially Pure)

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.
