Thanks to the excellent properties of titanium, it has become a common and popular choice in the eyewear industry. Titanium resists discoloration and deformation and has remarkable stability. Titanium frames for glasses are categorized into three main types – titanium alloy, beta-titanium, and pure titanium frames.
Read on below to learn more about titanium glass frames to help you make the right choice.

Features of Titanium Alloy Glass Frames
Titanium alloy glass frames have strong corrosion resistance, high strength, low density, and good mechanical properties. Spectacle frames made from titanium alloy don’t corrode easily because of moisture and are also lightweight. Their density is also lower compared to ordinary frames. These frames have strong firmness and don’t easily damage or fall off the skin.
Unfortunately, because of titanium alloys’ poor technical performance and the complex cutting processes, finished glass frames tend to absorb more chemical impurities like oxygen, hydrogen, carbon, and nitrogen.
Titanium alloy has a complicated production process and poor abrasion resistance. This explains the relatively high price of this type of material. The intricate workmanship also makes these frames more expensive than ordinary ones.
Titanium Alloy vs. Pure Titanium Frames for Glasses
Pure titanium frames for glasses are slightly lighter than titanium alloy frames but these two are both top-quality materials with an appearance that looks comfortable enough.
Glass frames made of pure titanium don’t have any contact with the oxygen in the vacuum during the process of welding. Titanium alloy glass frames are welded with slope shape, one of the easiest ways to set apart the two kinds of spectacle frames.
Frames made from pure titanium don’t have direct contact with titanium at the hinge, unlike titanium alloy spectacle frames that do. This quality of pure titanium frames makes them form obvious unsmoothed temples and wrinkles at the joints.
In general, pure titanium has a specific gravity of 4.5, and titanium alloy has 8.9 specific gravity which is double the gravity of pure titanium. This means that pure titanium frames for glasses are much lighter to carry by hand. This is another distinctive trait of these two spectacle frames.
Spectacle frames made from pure titanium are primarily made from 99% high purity titanium with no additional materials. The titanium alloy frame has a lens ring that is mostly titanium alloy, making the glasses’ firmness much better.
How to Distinguish Pure Titanium Frames
With its benefits including corrosion resistance, lightweight, high strength, anti-fatigue, and anti-allergy, pure titanium glass frames have now become the first option for fashion consumption among white-collar workers, college students, and elites.
With the continuous development and advancement of titanium materials and as the processing technology becomes more mature, many titanium-based spectacle frames have been introduced in the market. These include pure titanium, memory titanium, and beta-titanium.
But due to the increasing number of choices, it has become even more vigilant when choosing among the titanium frames for glasses to ensure that you will only get the best quality that suits your specific needs.
