How To Identify Pure Titanium Glasses Frame?
Titanium is widely used in the glasses industry because it is not easy to deform, fade and has strong stability. The spectacle frame made of titanium can highlight noble taste and elegant temperament. Spectacle frames made of titanium can be divided into pure titanium, titanium alloy and 阝titanium eyeglass frames.
Characteristics of titanium alloy glasses frame:
Low density, high strength, good mechanical property and strong corrosion resistance. The glasses frame made of this material is very light and not easy to be corroded by moisture. However, due to the poor process performance of titanium alloy, cutting is very difficult, so the spectacle frame made of titanium alloy absorbs more chemical impurities such as oxygen, nitrogen and carbon.
The anti-wear performance of titanium alloy is poor and the production process is complex. Therefore, each time the spectacle frame is made of this material, the cost is relatively high and the work is relatively complex. The seat is much more expensive than the ordinary spectacle frame.
Difference between pure titanium spectacle frame and titanium alloy spectacle frame
The titanium alloy spectacle frame is slightly heavier than the pure titanium spectacle frame, but these two are high-quality materials, so it gives people a comfortable feeling from the appearance.
During the welding process of pure titanium spectacle frames, they will not contact with oxygen in the vacuum. However, the welding marks of titanium alloy spectacle frames are like "slope". This is one of the most effective methods to distinguish these two kinds of spectacle frames.
The pure titanium spectacle frame will not directly contact with titanium at the hinge, while the titanium alloy spectacle frame will directly contact with titanium, which is easy to cause binding wrinkle, and the temple is obviously not smooth.
The specific gravity of pure titanium is generally 4.5, while that of titanium alloy is 8.9, which is equivalent to half of that of titanium alloy.
How to identify pure titanium glasses frame
1. Hand feeling weighing method
2. The method to identify the pure titanium spectacle frame is to observe whether there is a gasket at the hinge joint?
3. Magnetic reaction with magnet
4. Observe the welding point between the nose support stem and the nose support box
