Metal, TR90 and other materials of the sunglasses frame is more durable, the following is the specific analysis:
Metal material
Strong and durable: The metal has high strength and hardness and is not easy to break or deform. In particular, some high-quality alloy materials, such as memory alloy, have good elasticity and recovery, even if it is squeezed or twisted by external forces, it can be restored to the original shape.
Corrosion resistance: Some metal frames are treated with special electroplating or coating, which has good corrosion resistance, can resist sweat, rain and chemical erosion in the daily environment, and is not easy to rust or fade, extending the service life. However, some common metal frames if not properly maintained, there may be rust and other problems.
TR90 material
Ultralight and elastic: The TR90 frame is lightweight and comfortable to wear while offering excellent flexibility and elasticity. It can withstand a large degree of bending without breaking, when the external force disappears, it can be quickly restored to its original state, and is not easy to be damaged by daily wear or accidental collision.
High temperature resistance: This material has good thermal stability, is not easy to deformation in high temperature environment, can maintain the stability of its shape and performance, suitable for use in a variety of different environmental conditions.
Although plastic and natural frames also have their own advantages, in contrast, plastic materials are low in strength and easy to break, natural materials require more careful maintenance and are easily damaged by environmental factors, and are slightly inferior in durability.
