Titanium Tubing Grades Guide
CP grade 1 is the softest titanium with the highest ductility, good cold formability, which gives Titanium grade 1 an excellent resistance from mild to high oxidation. Commercially Pure Titanium grade 1 is one of the softest and most ductile grades, exhibiting the most outstanding formability. It also has excellent welding properties and high impact toughness. Titanium grade 1 is designated as UNS R50250.
CP grade 2 is used most widely in commercially pure titanium. Titanium grade 2 has moderate strength and excellent cold-forming properties. Titanium grade 2 is designated as UNS R50400. Thanks to its varied usability and wide availability, grade 2 Titanium is called the “workhorse” of the commercially pure titanium industry. It is “unalloyed” titanium offering an excellent balance of strength and ductility.
CP grade 3 is almost only used in the pressure vessel. Grade 3 titanium has excellent corrosion resistance.
Alloy grade 5, Ti-6Al-4V, is most widely used in titanium alloys because of its comprehensive mechanical, physical, and chemical properties. Titanium 6Al-4V, Titanium grade 5 alloy (UNS R56400) is the most widely used titanium grade. Titanium grade 5 is a two-phase α+β titanium alloy, with aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Grade 5 titanium has good welding and production characteristics.
Alloy grade 23, Ti-6Al-4V ELI (Extra Low Interstitial) is designated as UNS R56401, and Titanium grade 23 has a superior damage tolerance to other alloys. These benefits make Titanium grade 23 the ultimate dental and medical titanium grade.
Titanium 8Al-1Mo-1V is a near Alpha Alloy that is primarily designed for use at elevated temperatures – up to 455 degrees centigrade. It offers the highest modulus and lowest density of all Titanium alloys. It has good creep strength, and it’s weldable by the inert gas fusion and resistance welding processes.

Sizes and tolerances
Sizes and tolerances for titanium tubes
Titanium tubes are available in size range outside diameter 9.53-38.1 mm (3/8 – 1 1/2 in.) with wall thicknesses from 0.7 to 5 mm (0.0275 to 0.1968 in.)*.
OD = outside diameter
WT = wall thickness
| Size OD, mm (in.) | Tolerances OD, mm (in.) | WT min wall % |
| < 25.4 (< 3/8) | ±0.102 (0.004) | +20/-0 |
| 25.4-38.1 (1-1 1/2) | ±0.127 (0.005) | +20/-0 |
Tolerances for OD < 15.9 or > 38.1 – or closer tolerances – after special agreement.
