Knowledge about titanium frames


Titanium frame glasses are spectacle frames made of titanium metal, featuring light weight, high strength and corrosion resistance. They belong to mid-to-high-end consumer products.

Material properties
Titanium frames are mainly divided into two types: pure titanium and β titanium alloy. Pure titanium refers to materials with a titanium purity of over 90%, a density of 4.5g/cm3, a weight of only 40% of stainless steel, and a strength twice that of steel. β titanium alloys are added with elements such as aluminum and vanadium to enhance flexibility and elasticity. ?

Identification method
Youdaoplaceholder0 Weight comparison ? : The weight of a pure titanium frame is approximately half that of an alloy frame. You can make a preliminary judgment by weighing it. ?
Youdaoplaceholder0 Welding marks ? : Pure titanium welding presents a "stepped" shape weld mark, while alloy welding shows a "slope" shape. ?
Youdaoplaceholder0 Label check ? : If the temple is engraved with "100%TITANIUM" or "Ti-P", it indicates pure titanium. For β titanium alloy, it should be marked with "β-Titanium" or a similar label.

Development history
Japanese enterprises were the first to break through titanium processing technology in the 1980s. In 1981, they launched the TitexA/TitexB series. By 1998, titanium frames had occupied more than 60% of the Japanese market share. Domestic production still relies on imported titanium materials, and independent research and development is in its infancy. ?
Advantages and disadvantages

Youdaoplaceholder0 Advantages ? : Light weight (pure titanium weighs only 40% of stainless steel), corrosion-resistant, anti-allergic, and has good biocompatibility. ?
Disadvantages of ? : the material is relatively soft, and the design requires thick lines to ensure strength, resulting in a relatively high cost.
