Pure Titanium was developed uniquely to be produced eyeglasses focusing attention on its light (specific gravity is 4.51 ) , strong(30〜150) and corrosion resistance characteristics.
“It called Commercially Pure Titanium since there is a slight impure substance, but mostly pure from commercially point of view. “
The strength of Pure Titan depends on the contents of O and Fe and it is classified from GR-1 to GR-4. GR-1 is softest with less O and Fe and GR-2 is hardest with more O and Fe.
We are mainly dealing GR-1 and GR-2
