Titanium eyewear is one of the most common types of glasses. It is lighter and more flexible than acetate and metal eyewear, making it ideal for prescription glasses. Titanium eyewear is generally divided into pure Titanium Glasses and beta titanium glasses. In this article, we will focus on the advantages of pure titanium eyewear.
What is Titanium ?
First, let’s understand what titanium is. Titanium is a pure metal with a specific gravity of 4.5, high toughness, non-magnetic properties, and hypoallergenic characteristics. It is widely used in aerospace technology, jewelry, surgical instruments, and more, making it one of the most high-end materials in the eyewear industry. Pure titanium typically refers to titanium with a purity of over 89%, approaching 100% alpha-titanium metal. This metal features a high melting point, light weight, strong corrosion resistance, and a durable electroplated finish. So, what are the other advantages of pure titanium eyewear frames?
-
Lightweight: The primary advantage of pure titanium frames is their extremely light weight. Among eyewear materials, aside from carbon fiber—which is known as "black gold"—and aluminum, pure titanium frames are the lightest. While carbon fiber and aluminum manufacturing processes are more complex, resulting in generally wider frames, titanium glasses can have very thin borders. Thus, in reality, titanium eyewear is lighter than aluminum and carbon fiber eyewear.
-
Comfort and Durability: Glasses made from pure titanium are lightweight and comfortable, ergonomically designed, and have good flexibility. They do not deform or fade over time and do not cause skin allergies, making them quite durable. Titanium itself does not cause skin allergies, and the surface of titanium eyewear is often treated with an IP electroplating layer, which adheres well and is also hypoallergenic.
-
High Performance: Titanium is an essential material in modern aerospace, marine science, and nuclear power. It is 48% lighter than typical metal frames and offers excellent acid and alkali resistance, corrosion resistance, stability, high strength, and good elasticity. These properties make titanium ergonomic and non-toxic to the human body, with no radiation.
-
Electrical Properties: Pure titanium has unique electrical properties that can guide electronic fluctuations, creating ions that help ionize electric currents. This ionization can quickly adjust electromagnetic waves, mitigating adverse effects caused by disturbances in the body's bioelectric currents, leading to beneficial physiological effects. Additionally, titanium alloys can help relax muscles and alleviate stress.
While pure titanium is slightly less elastic than beta titanium, it is much more cost-effective. Therefore, when manufacturing glasses, finer parts such as the bridge or temples often use beta titanium to maintain the frame's lightweight and elastic properties.
