Advantages of titanium material:

1. High strength
The density of titanium is generally around 4.51g/cubic centimeter, which is only 60% of steel. The density of pure titanium is close to the density of ordinary steel. Some high-strength titanium exceeds the strength of many alloy structural steels.
2. High thermal intensity
The service temperature is several hundred degrees higher than that of aluminum alloy. It can still maintain the required strength at moderate temperatures and can work for a long time at temperatures of 450 to 500°C. These two types of titanium still have a high ratio in the range of 150°C to 500°C. Strength, while the specific strength of aluminum alloy drops significantly at 150°C.
3. Good corrosion resistance
Titanium works in humid atmosphere and seawater media, and its corrosion resistance is far better than stainless steel; it is particularly resistant to pitting corrosion, acid corrosion, and stress corrosion.
4. Good low temperature performance
Titanium can still maintain its mechanical properties at low and ultra-low temperatures.

Notes: ‌

1. Avoid using alcohol-containing cleaners: Some lenses cannot be cleaned with alcohol-containing chemicals, as this may affect the quality and color-changing effect of the lenses. ‌
2. Prevent frame deformation: Glasses are optical products. Improper use of the frame may cause deformation, affecting the wearing effect and vision health. ‌
3. Avoid high temperature environment: The color-changing effect of the lens may be affected in a high temperature environment. Avoid long-term exposure to extreme temperatures.
4. Adjust the frame appropriately: When the frame is loose, tighten it evenly, but not too tight, to prevent the lens from bursting under pressure.
5. Avoid strong impact: Although glasses are sturdy and durable, strong impact may cause the lens to break, affecting the use effect and safety.
