Pure titanium frames
Advantages of pure titanium frames
The light frame reduces the pressure of glasses on the bridge of the nose. Relatively comfortable and suitable for long-term wear.
High elasticity, high strength and wide bending range.
Corrosion-resistant and anti-allergic.
How to identify pure titanium frames
Light weight. Usually the weight of pure titanium frames is 5g~12g, which is only half of that of alloy frames.
Hinge combination. Pure titanium frames should not be in direct contact with the titanium in the hinge area, otherwise the joints will wrinkle and the temples will not open and close smoothly. Usually the hinge part of the pure titanium frame is inlaid with two thin gaskets to separate the upper and lower hinges. Therefore, checking whether there are shims at the hinges is also a good way to identify whether it is a pure titanium frame. If you look at the hinge joint from the inside of the frame, you'll notice a small groove that is specifically designed to facilitate the removal of the gasket.
Welding points. The welding of pure titanium materials is vacuum oxygen-free butt welding, and the weld marks on the nose pads of the frame are in the shape of "steps"; the welding of alloy materials is spot welding, and the weld marks are in the shape of "slopes". This is one of the effective ways to distinguish titanium frames from non-titanium frames, and full titanium frames from non-titanium frames.
Does not attract magnets. The pure titanium part of the frame will not react if touched with a magnet, while the alloy will generally be absorbed.
Why are pure titanium frames so expensive?
Titanium is not a rare metal. Its reserves rank fourth after aluminum, iron, and magnesium, and are 16 times the total reserves of copper, nickel, lead, and zinc on the earth. It stands to reason that when resources are scarce, prices will be higher. The reason why titanium metal reserves are so large but so expensive:
Now we all have aluminum pots and basins, but as early as the 19th century, aluminum was a rare precious metal, more expensive than gold. During the reign of Napoleon III of France, the king and ministers held banquets. The ministers all used gold and silver cups, but the king held an aluminum cup. Because the value of aluminum at that time depended entirely on the level of the aluminum smelting industry. With the invention of electrolytic aluminum technology, aluminum production increased dramatically and aluminum prices plummeted. Titanium is refined today just as aluminum was refined before the 19th century. The cost is quite high and production is limited. Therefore, it is only used in some extremely important fields, such as aerospace, electronic industry, precision instrument manufacturing, etc.
1. The production cost is high, and the selling price will naturally rise. The reason is not difficult to understand. The main reason for the high production cost of titanium metal is its refining technology. Although technology in various fields has become mature, there are still certain difficulties in refining titanium, so the cost must be high, and due to limited production, rare and expensive titanium glass will be sold at a higher price.
2. The production process is complex. The production of titanium frames requires special processing equipment, special welding technology and electroplating technology. It has many processing steps and high production cost. To make a complete pure titanium frame, welding technology is necessary. However, the welding process applied to titanium materials is still very different from other welding processes. Special processing equipment and special welding techniques are required.
3. Excellent performance. The quality of the glasses and their reliability during wearing and use often determine their price. The excellent properties of pure titanium glasses include light weight, high hardness, corrosion resistance, no rust, good thermal conductivity, good touch, anti-allergy, memory function, etc. These are the reasons why people like it.
To sum up, there is a reason why pure titanium glasses are expensive. And despite being expensive, they still attract people's attention, mainly because pure titanium glasses rely on their excellent texture and reliable craftsmanship to create a high-quality end product with countless advantages, making people happy to carry them in their pockets . Pure titanium frames are lightweight and comfortable and are the lightest of all frame materials. In particular, it is also anti-allergic, corrosion-resistant, high-strength, and not easily deformed... It is simply a work of conscience!
Currently, titanium-based frames on the market mainly include pure titanium, beta titanium, memory titanium and other frames. "Titanium" metal is so popular, naturally there are some unscrupulous merchants who make profits by selling inferior quality, substandard and fake "pure titanium eyeglass frames".
