In the earlier days, pure titanium metal eyewear processing is major on pure titanium, but in order to greatly pursue metal eyewear strength, flexibility, and improving welding difficulty grade, other metal elements such as aluminum, vanadium, molybdenum are added in pure titanium metal eyewear.
As pure titanium metal eyewear processing techniques and workmanship are difficult, titanium metal eyewear is high valued-added and sells much expensive than normal metal eyewear and has becoming the fashion trends, pure titanium is one favorite eyewear material now widely used in optical frame and sunglasses model. Refers to pure titanium metal eyewear, it means titanium components reaches to 99% or more. It has some difficulties in machining processing, welding, electroplating and so on, so the pure titanium application is subject to certain restraint.
In order to identify pure titanium and titanium alloy metal eyewear, consumers can refer to the below two points.
Pure titanium metal eyewear was marked with the abbreviations or full name in the frame, usually on the temples or on demo lens. It marked “Ti” “Ti-P” or “ Pure Titannium” or “Titannium”.
Usually, titanium alloy metal eyewear was marked with abbreviations in the frame, on the temples or on demo lens. It marked β-Ti or β-Titanium.
