What is the difference between pure titanium spectacle glasses frames and titanium alloy spectacle glasses frames? Titanium alloy glasses frames are slightly heavier than pure titanium eyewear frames, but they are both high-quality materials, so they give a comfortable appearance.

During the welding process, pure titanium material glasses frames do not come into contact with oxygen in the vacuum. However, titanium alloy glasses frames are welded (known as spot welding), and the welding marks appear in a "slope" shape, which is one of the most effective methods to distinguish between these two types of glasses frames.

The pure titanium eyewear frame is located on the hinge and will not come into direct contact with titanium; The titanium alloy glasses frame will directly come into contact with titanium, which can easily cause wrinkles at the joint and obvious poor opening and closing of the lens legs.

The specific gravity of pure titanium is generally 4.5, while titanium alloy is 8.9, which is equivalent to half of titanium alloy material. So the glasses frame made is relatively light to handle by hand, which is the simplest way to distinguish between these two types of glasses frames.

The pure titanium eyewear frame mainly consists of 99% high-purity titanium material, excluding other materials. The mirrored ring of the titanium alloy eyewear frame is mainly made of titanium alloy, making the firmness of the glasses better.
