The frame is an important component of eyeglasses online cheap, mainly serving to support the lenses. If you want to choose a frame that suits you, you need to first understand the material and characteristics of the frame.
So what are the materials of the mirror frame? What are their characteristics? Carbon fiber material is lighter in eyeglass frame materials, and tests have shown that carbon fiber of the same volume is lighter than titanium frames and lighter than metal.
Its essential attribute is that it is relatively lightweight, and the weight-bearing sensation on the nose bridge can be greatly reduced when worn. The lightweight frame makes you forget to wear glasses.
Thin mirror legs are lighter than others, even lighter than aluminum, but stronger than iron. The eyeglass frames made with them have the characteristics of wear resistance, impact resistance, softness, and high and low-temperature resistance.
Pure titanium generally refers to a-titanium metal materials with a purity of over 89% and infinitely close to 100%. The specific gravity of titanium is only 4.5, it is corrosion-resistant, and titanium has become mainstream on eyeglass mart. Titanium frames are generally represented as Ti-P or TiTAN and are mainly made of titanium except for brackets, hinges, and screws.
The eyeglass frame made of pure titanium is lightweight and comfortable, more ergonomic, and has good flexibility. It does not deform or fade after long-term use, and is less likely to cause skin allergies, making it more durable.
Memory titanium alloy frame refers to a new alloy composed of nickel and titanium in an atomic ratio of 1:1. Memory titanium material is more corrosion-resistant than Monel alloy and high nickel alloy, but slightly inferior to pure titanium and beta titanium.
Very good elasticity, exhibiting shape memory characteristics below 0 ℃ and high elasticity between 0-40 ℃, lighter than general alloys.
