We at Aerocom Metals supply all grades of Commercially Pure titanium and titanium alloys in accordance with AMS, ASTM, MIL specification or equivalent. Please Download our Titanium Info Sheet for full specifications.
Grade 1 is slightly purer than Grade 2 (at approximately 99.8%), and therefore more formable. It is used as the surface protective (titanium) layer in Explosively Clad (bonded) plate or parts, as well as for the complex shaped plates in Plate & Frame heat exchangers, due to its ability to be deep drawn.
Grade 2 is the most widely used of the CP (Commercially Pure) Grades. Products include Tube (welded & seamless), Pipe, Plate, Sheet/Strip, Fasteners, Fittings, Pumps and Valve bodies. It is approximately 99.6% pure and is the primary material for marine applications.
Grade 5 is the most widely used titanium alloy. It has very high strength but relatively low ductility. The main application of this alloy is in aircraft and spacecraft as well as in valves for industrial equipment. Offshore use is growing. The alloy is weldable and the precipitation can be hardened.
Grade 9 is a higher strength alloy, originally developed for increase of corrosion resistance for the Chemical Process Industry (CPI) for use in severe corrosive environments, designed to withstand crevice corrosion at low pH levels and at higher temperatures to 5000F (2600C). It has application in ship service as stack liners, providing corrosion resistance from the hot combustion gases and extending the (material replacement) life and port maintenance from every 6 months to several years.
Grade 23 is an Extra Low Interstitial (ELI)version of Grade 5. It is used where Stress Corrosion Cracking (SCC) is a concern, in applications where the 6Al - 4V alloy would normally be thought to be the material of choice, BUT where the application is under stress conditions. The lower interstitials (Fe, O2 and N2) give significant improvement to eliminating the SCC concerns.
