Ti-6Al-4V titanium alloy commonly exists in alpha, with hcp crystal structure, (SG : P63/mmc) and beta, with bcc crystal structure, (SG : Im-3m) phases. While mechanical properties are a function of the heat treatment condition of the alloy and can vary based upon properties, typical property ranges for well-processed Ti-6Al-4V are shown below.

Grade 37 contains 1.5% aluminium. Grade 38 contains 4% aluminium, 2.5% vanadium, and 1.5% iron. This grade was developed in the 1990s for use as an armor plating. The iron reduces the amount of Vanadium needed as a beta stabilizer. Its mechanical properties are very similar to Grade 5, but has good cold workability similar to grade 9. [35]
Ti-6Al-2Sn-4Zr-2Mo (UNS designation R54620), also known as Ti 6-2-4-2, is a near alpha titanium alloy known for its high strength and excellent corrosion resistance. It is often used in the aerospace industry for creating high-temperature jet engines and the automotive industry to create high performance automotive valves.
In the direct powder rolling (DPR) process BE powder is used to produce sheet and plate and composite multilayered sheet and plates. Sheets between 1.27 and 2.54 mm and 50 to 99+% dense of single layer CP titanium, Ti Grade 5, TiAl (Ti-48Al-2Cr-2Nb) and composite Ti/Grade 5/Ti and Grade 5/TiAl/Grade 5 have been produced by DPR and sintering.
When used on Grade 5 titanium it will produce an oxide layer 17.5 nm thick and a surface roughness of 3.4 um total height profile (R t). [7] In a chromic acid treatment the anodization is typically done at 5 or 10 volts. The 1982 study referred to above stated that the 5 volt performed better than the 10 volt as a function of average crack opening.
Titanium Beta C refers to Ti Beta-C, a trademark for an alloy of titanium originally filed by RTI International. [1] It is a metastable "beta alloy" which was originally developed in the 1960s; Ti-3Al-8V-6Cr-4Mo-4Zr, nominally 3% aluminum , 8% vanadium , 6% chromium , 4% molybdenum , 4% zirconium and balance (75%): titanium .
The steeper angle gives anatase crystals a longer vertical axis and skinnier appearance than rutile. Additional important differences exist between the physical characters of anatase and rutile. For example, anatase is less hard (5.5–6 vs. 6–6.5 on the Mohs scale) and less dense (specific gravity about 3.9 vs. 4.2
