Titanium metal has excellent characteristics, known as the "space metal", is the "third metal" after aluminum, is the most promising metal, with its light, corrosion resistance, anti-allergy, anti-fatigue strength high advantages. As a new type of eyewear material, titanium metal has been favored by more and more manufacturers.
With its light, corrosion resistance, anti - allergy, anti - fatigue strength, titanium metal as a new type of eyewear data came out. It is favored by more and more manufacturers. With the development of titanium materials and processing technology is increasingly naive, the market has appeared in pure titanium, B titanium, memory titanium and many other titanium plates based on titanium metal. Among them, the purity of titanium plate of pure titanium material is required to reach 99.9%, without gaskets, screws, stipules and leg covers). Its label is called PURETITA NIUM or ti-P in short. But individual manufacturer under the interest of some non pure titanium or titanium alloy materials are also more than the logo, plus some glasses dealers and consumers lack of identification ability of pure titanium, titanium plate, titanium plate after causing consumer wear titanium frame the phenomenon such as rust, skin allergies, harm the interests of glasses dealers and consumers. Several simple and convenient methods for identifying pure titanium titanium plates are described below.
The identification of titanium rod and titanium wire is the most commonly used is the most easy to think of, is to use the magnet to attract, use the magnet to do magnetic reaction titanium plate hinge as far as possible loose. If the mirror leg is shaking under the attraction of the magnet, it indicates that the titanium plate is not pure titanium material, otherwise it indicates that the titanium plate may be titanium. To sum up, it is not enough to judge whether the titanium plate material is pure titanium merely from the mark, but also to combine the above several methods for comprehensive evaluation, so as to identify the authenticity of the titanium plate. Two thin spacers are usually embedded in the hinge of a pure titanium mirror, separating the upper and lower hinges. Therefore, checking whether there is a gasket at the hinge is also a good way to identify whether the plate is pure titanium. Viewing the hinge joint from the inside of the titanium plate, you will find a small groove, which is specially designed to facilitate the removal of the gasket.
It's lighter in your hands. This is one of the easiest ways to distinguish between a titanium frame and a non-titanium frame. With the weight of the hand usually alloy frame specific gravity is about 8.9g/cm3 pure titanium frame specific gravity is 4.5g/cm3, due to the titanium material is equivalent to half of the alloy frame. The welding mark is "step" shape; The welding of alloy data is spot welding, and the welding of pure titanium material is oxygen-free bump welding for the welding points of nose bracket and nose bracket. The "slope" shape of the welding mark is one of the effective ways to distinguish between titanium and non-titanium, full titanium and non-full titanium. If there is pure titanium gasket in the hinge part, it is not suitable to make direct contact with titanium and titanium. Observe the joint of the hinge, otherwise it is easy to appear the wrinkling of the joint and the phenomenon of poor opening and opening of the mirror leg
