2, TR90 frame: This is a super tough resin material, characterized by good flexibility, wear resistance, impact resistance, light and comfortable to wear, suitable for long-term wear.
3. W-C plastic steel frame: made of W-C plastic steel, which combines the advantages of plate and TR90, has the characteristics of high elasticity, high strength, high temperature resistance and impact resistance, and is light in weight and suitable for various occasions.
4. Alloy frames: These frames are made of metal alloys such as copper, nickel and titanium. Their advantages are durability and corrosion resistance, but their disadvantages are heavier, which leads to skin allergy.
5, pure titanium frame: pure titanium material is extremely strong, light weight, strong corrosion resistance, skin-friendly, suitable for people who are allergic to metals.
6.β titanium frame: β titanium is a titanium alloy, which maintains most of the advantages of pure titanium, and at the same time increases the elasticity and plasticity of the frame, making it more suitable for facial curves.
7. Monel alloy spectacle frame: This alloy has good mechanical properties and corrosion resistance, and is suitable for making high-grade spectacle frames.
