How To Identify Pure Titanium Eyeglass Frames?

1. Measure the weight of the spectacle frame by hand. Usually the specific gravity of the alloy frame is about 8.9 grams per cubic centimeter, and the specific gravity of the pure titanium frame is 4.5 grams per cubic centimeter. Since the weight of titanium material is equivalent to half of the alloy frame, It will weigh less in the hand, which is one of the easiest ways to tell the difference between a titanium frame and a non-titanium frame.
2. Observe the welding points of the nose pad stem and the nose pad box. The welding of pure titanium materials is oxygen-free butt welding, and the weld marks are step-shaped. The welding of alloy materials is spot welding, and the weld marks are slope-shaped. This is to distinguish the titanium frame. One of the effective methods for all-titanium and non-titanium frames.
3. Observe whether there are gaskets at the hinge joint. Usually, two thin gaskets are embedded in the hinge part of pure titanium mirrors to separate the upper and lower hinges. Therefore, checking whether there are gaskets at the hinges can also identify whether the glasses frame is A great way to get pure titanium frames.
4. Use magnets for magnetic reaction, loosen the hinges of the frame as much as possible, and use magnets to attract them in a free-moving state. When the temples sway under the attraction of the magnets, it means that the frame is not made of pure titanium, and vice versa. The frame may be titanium.
