It is a blend of 6% aluminum, 4% vanadium and 90% titanium (as well as trace amounts of iron and oxygen; max 0.25% and 0.2% respectively), and is one of the strongest and most lightweight of other known compositions. Aircraft grade titanium is often used in crafting titanium rings due to its advantageous and suitable properties (compared with other titanium compositions), as well as its wide commercial availability.

The cost of titanium rings can be very high. This is ostensibly because the process of extracting titanium from its various ores is laborious and costly. Although it is indeed expensive as an engineering material, it is far less expensive than the jeweler's usual precious metals, even
493:. The process of inlaying involves crushing the metals into channels, which are then trapped under pressure. On a ring, this usually results in metals sitting side-by-side on the surface – for example, a strip of gold running through the middle of an otherwise titanium ring.
