Titanium and aluminum are both light metals that get specified to save weight, so they end up competing for the same aerospace, marine and high-performance jobs. The trade is clear once you line them up: aluminum is lighter and far cheaper, titanium is much stronger, holds heat, resists corrosion and survives fatigue. This page compares […]

Titanium and stainless steel both resist corrosion and both get specified for chemical, marine and process work, so buyers often have to choose between them. Titanium wins on corrosion in chlorides and on strength-to-weight, stainless wins on price and ease of fabrication, and there is a band of jobs where either would work and budget

Grade 1 is the softest commercially pure titanium, UNS R50250, Werkstoff 3.7025. ASTM B265 sets 240 MPa minimum tensile strength with 24 percent minimum elongation and holds oxygen to 0.18 wt%. That combination makes it the grade for deep drawing, cladding, explosive-bonded plate and wire. Grade 1 titanium is the softest and most formable of

Grade 12 titanium is Ti-0.3Mo-0.8Ni, UNS R53400, Werkstoff 3.7105. ASTM B265 specifies 0.2 to 0.4 wt% molybdenum with 0.6 to 0.9 wt% nickel, giving about 483 MPa minimum tensile strength and a higher crevice corrosion threshold than Grade 2 in hot brine, at lower cost than the palladium grades. Grade 12 titanium is the corrosion-upgrade

Grade 9 titanium is Ti-3Al-2.5V, UNS R56320, Werkstoff 3.7195. Minimum tensile strength is about 620 MPa, against 345 MPa for Grade 2 and 895 MPa for Grade 5. It stays cold formable and weldable at that strength, which is why it is the grade most often drawn into tube. Grade 9 titanium sits between commercially

Grade 2 titanium is commercially pure (unalloyed) titanium, UNS R50400, Werkstoffnummer 3.7035. ASTM B265 and B348 set it at 345 MPa (50 ksi) minimum tensile strength with 20 percent minimum elongation. It is the most used of the four commercially pure grades, holding working strength and seawater corrosion resistance while staying formable and weldable. Grade

Grade 5 titanium is Ti-6Al-4V, UNS R56400: an alpha-beta alloy of 5.50 to 6.75 % aluminum and 3.50 to 4.50 % vanadium, balance titanium. Minimum tensile strength is 895 MPa against 345 MPa for commercially pure Grade 2, at a density of 4.43 g/cm3. It is the grade specified when commercially pure titanium is not

Grade 7 is commercially pure titanium with 0.12 to 0.25 wt% palladium per ASTM B265, UNS R52400, Werkstoff 3.7235. Strength matches Grade 2 at 345 MPa minimum tensile, so the palladium buys corrosion performance in reducing acids rather than mechanical properties. Grade 7 titanium is commercially pure titanium with a small palladium addition. ASTM specifies
