Introduction of common glasses frame materials

The following will introduce the common materials of glasses frames, as well as the advantages and disadvantages of each material.

(1) TR90 material
The glasses frame, the veteran level, is also the entry-level glasses frame for many people, and it is made of TR90. It has a very wide range of use, regardless of age, will bring it. This material was first invented by Koreans and used in the manufacture of glasses.

Advantage:
1. The material is light, and it will not feel heavy or heavy on the belt;
2. Excellent flexibility, not easy to deform, good elastic strength, can be bent at will without breaking.
3. Anti-allergic (some people have metal allergies).

Shortcoming:
1. The application is basically injection molding, this material cannot be adjusted after it is made into a finished product;
2. The surface layer of the frame is easy to peel off or fade during use. If the metal hinge is not used, the frame is easy to be damaged and not durable.

3. Few styles

(2) Pure titanium
It looks no different from the alloy material. Pure titanium refers to the alpha titanium metal material with a titanium purity of more than 99%. Its characteristics are: high melting point, light material, strong corrosion resistance, and strong electroplating layer. Pure titanium is commonly used in annealing, solid solution and aging heat treatment methods. Annealing is to eliminate internal stress, improve plasticity and stability, and obtain better overall performance.

Advantage:
1. Good toughness, not afraid of breaking,
2. It is not allergic to skin contact. For children's shoes with metal allergy, you can use it with confidence
3. It is not easy to fade, durable, not easy to deform, and the electroplating layer is not easy to fall off
4. Super light, generally only a few grams per frame, super comfortable to wear

Shortcoming:
1. High cost
2. The material is too soft, and the frame cannot be made more delicate. Only by making the lines thicker can the stability and strength be ensured.

(3) Titanium alloy

Advantage:

1. The frame made of titanium alloy is 48% lighter than other alloy frames.
2. Strong toughness, acid and alkali resistance, corrosion resistance, high stability, high strength, good elasticity, easy coloring on the surface, beautiful and durable.

Shortcoming:
1. High cost

(4) Acetate material
It feels like a wooden texture, but it is not woody. It has a good texture and is relatively small. It will not feel like a bad street.

Shortcoming:
1. Very heavy and uncomfortable after taking a long time
2. Poor toughness,


The above are the most common materials
In terms of price: tr90 is the cheapest, followed by alloys, then plates, and finally titanium alloys and pure titanium
In terms of weight: pure titanium and titanium alloys are the lightest, tr90, followed by alloys and plates

In terms of styles: alloy styles are the most》 pure titanium (because of the high cost, there will not be too many styles in general optical shops)》 tr90》 plate.

Now you know how to choose the materials? 

Thanks for reading.
