Why different grades of Titanium?
No doubt you have noticed that there are many different grades of titanium jewelry on the market. Most titanium jewelry products being sold are some type of alloyed titanium – not pure titanium. We use a commercially pure (CP) grade of titanium. Within the CP category the most popular are grades 1 through 4. CP Grade 1 is the softest and Grade 4 is the hardest. The primary difference between the grades is the quantity of Oxygen, the addition of which creates the increases in hardness. We use CP Grade 2 in all of our gray titanum products. We found it to be the ideal balance between titanium’s hardness and workability. It can be cut off, refinished, and engraved, yet it is resistant to marring and polishes well.
