ERTi-1
CP-1 Titanium is the lowest strength unalloyed (or Commercially Pure--CP) grade. Grade 1 is used in the applications where ductility is paramount, such as explosive cladding, loose linings, expanded metal, and deep drawing applications. It is also used in electrolytic applications like coated anode substrates for production of chlorine and sodium chlorate.
ERTi-2
CP-2 Titanium is the "workhorse" of the industrial corrosion market and most common unalloyed (or Commercially Pure--CP) grade. Grade 2 is generally the most readily available in all product forms and has the lowest cost. It is used for process equipment like pressure vessels, columns, tanks, heat exchangers, shafts, blowers and fans, condenser tubing, valves, fittings, and pipe.
ERTi-3
CP-3 Titanium is a higher strength unalloyed (or Commercially Pure--CP) grade. Grade 3 is used for process equipment, tubing and pipe. Grade 3 is not as readily available as CP-2, but should be considered in applications where its higher strength reduces metal thickness required, and where the quantity of metal justifies a mill purchase.
