Titanium Alloy Glasses Frame: The Perfect Blend Of Lightness, Fashion And Quality

In daily life, our closest contact with titanium, a metal, may be the titanium alloy glasses frame we wear. When walking into an optician to choose a frame, many people will feel confused in the face of the many introductions of pure titanium and semi-titanium in the store's mouth.

1. Why Are Titanium Alloy Glasses Frames Favored?

The reason why titanium alloy glasses frames are favored is due to their many outstanding advantages. Titanium House is concerned that the application of titanium alloy in the glasses industry is the perfect combination of materials science and fashion aesthetics.

From the point of view of physical properties, titanium alloy is light in weight and has a density of about half that of steel. This makes titanium alloy glasses frames very light to wear, and long-term use will not cause excessive burden on the bridge of the nose and ears, which greatly improves the comfort of wearing. Taking Xiaomi anti-blue light glasses Pro as an example, it uses β-titanium alloy temples, combined with ultra-thin one-piece molding technology and ergonomic 3D curved surface design, the thickness of one side is controlled within 1.2mm, and the weight of the whole machine is only 22 grams. Even if it is worn continuously for 8 hours, it will not produce the feeling of pressure on the ears of traditional metal frames.

The hardness of titanium alloy is high, about twice that of stainless steel and ordinary steel, twice that of iron, and six times that of aluminum. In the ultra-low temperature world, titanium will become harder and have the properties of a superconductor, while steel will become fragile and incompetent. This feature ensures that the glasses frame is not easy to deform in daily use, can maintain its original shape for a long time, and provides a strong guarantee for the stability and service life of the glasses.

Corrosion resistance is also a highlight of titanium alloy. Titanium is soaked in the sea for five years and does not rust. Even in a humid environment, it can maintain a good appearance and performance. There is no need to worry about the appearance and use due to corrosion.

This characteristic of titanium alloy makes it widely used in the manufacture of equipment such as chemical industry, seawater desalination, and seawater cooling in power plants, and now it also shows strong advantages in the glasses industry.

In addition, titanium alloy glasses frames also have a wealth of color options, and their unique metallic luster adds a sense of fashion to the glasses, which can meet the pursuit of personalization and fashion by different consumers. Moreover, it also has the advantages of hypoallergenic and wear-resistant. It is an ideal choice for people with sensitive skin. At the same time, it can withstand friction and collisions in daily use and keep the glasses intact.

2. Common Materials Of Titanium Alloy Glasses Frames

The materials commonly used in the production of titanium alloy glasses frames are mainly divided into two types: pure titanium and semi-titanium;

1) Pure titanium, the English logos are Titanium, pure titanium, Titanium-IP, etc. Only when the purity of titanium reaches more than 90% of the titanium metal material, it is eligible to be called pure titanium glasses. Pure titanium glasses frames have high strength and corrosion resistance, light texture, good biocompatibility, and are more comfortable to wear, but the price is relatively high. Pure titanium frames should not be in direct contact with titanium in the hinge part, otherwise they are prone to wrinkling at the joint and poor opening and closing of the temples. Usually, two thin gaskets are inlaid in the hinge part to separate the upper and lower hinges. At the same time, the welding of pure titanium material is oxygen-free touch welding, and the welding marks are “stepped”.

2) Semi-titanium, usually refers to β-titanium, also known as titanium alloy Tc4.Β-titanium is a kind of metallographic organization of titanium alloy, which is called β titanium (B titanium) by people in the industry. Frames made of β titanium will show recovery when subjected to certain external pressure, and they have excellent plasticity. This makes β-titanium glasses frames not only lighter, but also able to design more novel and unique shapes and styles to meet consumers' diverse needs for fashion and personalization. For example, the β-titanium alloy temples of Xiaomi anti-blue light glasses Pro can accurately rebound to their original form even after severe bending. This physical characteristic not only improves the durability of the product, but also realizes a non-oppressive fit design. The welding of β-titanium material is spot welding, and the welding marks are "slope”-like. This is also one of the effective methods to distinguish between titanium frame and non-titanium frame, all-titanium and non-all-titanium frame.

3. The Production Process Of Titanium Alloy Glasses Frame

The birth of a pair of titanium alloy glasses frames requires at least 100 fine processes.

The first is the choice of raw materials. High-quality titanium alloy materials are an important prerequisite for making high-quality glasses frames. Titanium alloy is a kind of metal material with high strength, low density and corrosion resistance. It has great advantages when used in the production of glasses frames. The next step is mold making. The mold is like a “blueprint” for glasses frames. It requires the use of high-precision machining machines and is operated by experienced technicians. The production of molds is not one-time molding, but several trial production is required, and the structure and size are constantly adjusted until the appropriate mold structure and size are reached.

After the mold is made, enter the extrusion link. The titanium alloy material is placed in a mold, an extruder is used to process it into the desired shape, and a certain pressure is applied at the same time to make it have better strength and toughness. Then there is the stamping process, which is an important step to make the glasses frame beautiful. Suitable process equipment is selected, and the titanium alloy material is pressed and processed by fitting the mold to make the shape of the glasses frame more exquisite.

Finally, there is fine processing, including polishing, cleaning, polishing and other links. Every step requires careful care, just like doing an “all-round SPA” for the glasses frame to give it a charming luster. Every aspect of making high-quality titanium alloy glasses frames is sloppy, because every detail is directly related to the quality and performance of the glasses frames.

4. Identification Method Of Titanium Alloy Glasses Frame

For consumers, how to identify the real titanium alloy glasses frame is essential. We provide you with the following practical methods.

1) Look at the details, the titanium "ID card".

The real titanium frame must be engraved with an exclusive logo on the inside of the temples. Pure titanium is marked “TITANIUM” or “T-P”, and β titanium is marked “β-TITANIUM”.The edges of these laser-engraved letters are clear and burr-free, and the nails are uneven. At the same time, observing the hinge, the metal primary color of the titanium frame presents a unique cold-toned silver gray, which is different from the bright white of stainless steel or the dullness of the alloy. You can also observe the welding points of the nose pads and nose pads. The welding of pure titanium materials is oxygen-free touch welding, and the welding marks are “stepped”; the welding of alloy materials is spot welding, and the welding marks are “slope”.

2) Weigh the weight and subvert the light weight of cognition.

Compared with a metal frame of the same size, the weight of the titanium frame will be amazing. The density of pure titanium is 4.5g/cm3, and the density of β titanium is 4.8g/cm3, which is 40% lighter than stainless steel. Specifically, a standard-size full-frame titanium frame is about 15-18 grams, which is equivalent to the weight of three one-dollar coins.

3) The magnet test to crack the metal code.

The magnet you carry with you is the best detection tool. Pure titanium and β titanium have no reaction to magnets at all, while stainless steel and Monel alloys common in the market will be obviously adsorbed. Note that some inferior products will use titanium-clad steel technology. At this time, magnets can be used to test the inside of the temples or welding parts.

4) Observe the oxidation traces and the answer given by time.

Using a titanium frame for more than 3 months, the nose pads and temples will show unique oxidation marks at the bend. The real titanium oxide layer is a uniform light golden color, similar to champagne, while ordinary metal oxidation will turn black or green rust.

5) Compare prices and the magic mirror of market laws.

The current price of titanium raw materials is about RMB￥200/kg, which is 10 times that of ordinary alloys. The cost price of pure titanium frames in formal channels is not less than RMB￥300, and β titanium is not less than RMB￥500. If you encounter a " RMB￥199 special offer for pure titanium frames”, it is recommended to be vigilant. Note that some brands will use titanium alloy (titanium content of more than 50%), and such products should be marked with specific composition proportions.

6) The ultimate verification, professional testing method.

Merchants can be required to provide material inspection reports, focusing on spectral analysis data, and the titanium content should be ≥99%. In jewelry appraisal institutions, tested with a Mohs hardness tester, the hardness of pure titanium is 5-6, which can be scratched by a utility knife, while the hardness of stainless steel is 7-8, which cannot be scratched by ordinary knives.
