These alloys are commonly referred to as commercially pure (
C.P.) titanium with the level of impurities and mechanical
properties increasing slightly from ERTi-1 to ERTi-4.
C.P. Grade 2 titanium (ERTi-2) is the most widely used titanium alloy for industrial applications because of its good balance of strength, formability and weld ability. Typical uses are in seawater and brackfish water heat exchangers, chemical process heat exchangers, pressure vessels and piping systems, pulp bleaching...
