1. Advantages of pure titanium frames:
(1) The frame is light, reducing the pressure of glasses on the bridge of the nose, more comfortable and suitable for long-term wear.
(2) Elasticity, high strength and large bending range.
(3) Resistant to corrosion and allergies.
2. The method of identifying pure titanium frames:
(1) light weight, usually pure titanium frames for 5g ~ 12g, only half of the alloy frame.
(2) Welding for the "table" shape, this refers to the frame of the nosepiece at the weld, pure titanium is generally vacuum oxygen-free welding, so are "step" shape, while the alloy for the spot welding, welding for the "slope" shape. (2) The alloy is spot welded, and the weld is "slope" shape.
(3) does not absorb magnetism, pure titanium frame with a magnet to touch, is no reaction, while the alloy will generally adsorption.
