Titanium rings have seen a dramatic rise in popularity recently. This can be attributed to several factors. Titanium is highly resistant to corrosion and it is inert. So, there is no chance of developing an allergic reaction to the metal.

Titanium has the highest strength to weight ratio of any metal. It is commonly alloyed with other steel, aluminum, and other metals to create strong light weight alloys. Commercially pure titanium is as strong as low grade steel, yet weighs 45% less. 6-4 Titanium is commonly referred to as 'Aerospace' grade titanium. The '6-4' means that the titanium was alloyed with 6% aluminum and 4% vanadium.

Titanium was first discovered in 1791 by William Gregor in Cornwall, England. Its symbot is Ti and its atomic number is 22.
