What is the difference between pure titanium glasses frames and ordinary frames? Which is better? How to identify true and false?
Which one is better, ordinary spectacle frame or pure titanium spectacle frame?
1. Ordinary spectacle frames are prone to various deformations, and there are many scratches on the ordinary spectacle frames, which are not beautiful. The material of the pure titanium spectacle frames is made of "space metal" aviation materials, which are not easy to be deformed, and wear-resistant. Ordinary glasses are much better.
2. Ordinary glasses frames will feel a little dizzy and fatigued after wearing them for a long time. This is mainly due to the weight of ordinary glasses. As we all know, ordinary glasses are relatively heavy and will feel uncomfortable after wearing them for a long time. However, the advantage of pure titanium glasses frames is that they are light in weight. , so there will be no feeling when wearing it, only the weight of the lens.
3. Ordinary spectacles frames are thicker, they don’t look good when they are worn, and even lower a person’s appearance, but pure titanium glasses are generally slender frames, which will give people a refined look when they are worn. I feel that many stars will also wear pure titanium frames to match.
4. The pure titanium glasses frame has strong toughness and durability. The pure titanium glasses frame is not only light in material, but also has strong toughness, and will not be deformed or faded after long-term use. Not only that, but also have the advantages of acid and alkali resistance, corrosion resistance, high stability, high strength, good elasticity and so on.
5. Pure titanium has special current characteristics, which can guide electronic fluctuations to generate ions, so that the current tends to be ionized, and positive and negative ions can quickly adjust the adverse effects of electromagnetic waves caused by the disorder of the body's biological current, and have beneficial physiological effects on the human body.
What is the difference between pure titanium frames and titanium alloy frames?
Pure titanium refers to titanium metal materials with a titanium purity of more than 89%, high melting point, light material, strong corrosion resistance, and strong electroplating layer. Pure titanium spectacle frames have the advantages of being light and comfortable. They are the lightest among spectacle materials, have good hardness, are not easily deformed, are corrosion-resistant, do not cause skin allergies, and are more durable.
The titanium alloy frame has good elasticity, and the frame made of titanium alloy will automatically return to its original state when subjected to a certain external pressure. Therefore, the temples and middle beams of many spectacle frames are usually made of titanium alloys. Titanium alloy frames are generally thinner, which makes the frame appear lighter.
The glasses frame made of pure titanium material will not come into contact with the oxygen in the vacuum during the welding process, and the titanium alloy glasses frame will directly contact the titanium, which is easy to cause wrinkles at the joints and obvious poor opening and closing of the temples. Generally speaking, the specific gravity of pure titanium is 4.5, while that of titanium alloy is 8.9, and the material is equivalent to half of titanium alloy. Therefore, pure titanium eyeglass frames are much lighter than titanium alloy eyeglass frames.
How to identify the true and false of pure titanium glasses?
1. Weight
The advantage of pure titanium glasses frames is that they are light in weight, so pure titanium glasses are very light. Generally, you can know whether they are true or false by weighing them with your hands. This is also a relatively simple way to distinguish whether they are pure titanium glasses.
2. Look at the hinge part
Because the pure titanium frame should not make direct contact between titanium and titanium at the hinge part, otherwise the joints will be wrinkled and the temples will not be opened and closed smoothly, so two thin pads are usually embedded in the hinge part of the pure titanium glasses. piece to separate the upper and lower hinges. Therefore, checking whether there are spacers at the hinges is also a good way to identify whether it is a pure titanium frame.
3. Observe the welding point
The welding of pure titanium material is oxygen-free butt welding, and the welding mark is "step"; the welding of alloy material is spot welding, and the welding mark is "slope", which is also the difference between titanium frame and non-titanium frame, full titanium and non-full titanium frame. One of the effective methods of titanium frame.
4. With or without magnetism
Pure titanium glasses are not magnetic, you can loosen the hinge of the frame as much as possible, and use a magnet to attract it in a free movement state.
5. Price
The material used in the pure titanium spectacle frame is "space metal" aviation material, so the price is relatively expensive.
6. Logo
Under normal circumstances, pure titanium frames will be marked with 100% TITANIUM or PURETITANIUM on the temples or lenses. If there are no two marks, then it is generally not a pure titanium frame.
