Titanium eyeglasses are eyeglass frames made primarily of titanium or its alloys. Due to their excellent properties such as lightweight, high strength, corrosion resistance, and hypoallergenicity, they have become one of the mainstream choices for high-end eyeglasses.
Pure titanium: Titanium purity ≥99% (some standards specify ≥90%), nickel-free, biocompatible, suitable for sensitive skin.
β-titanium: Titanium content approximately 74%~77%, with added aluminum, vanadium, chromium, etc., offering better elasticity and easier processing into intricate designs.
Memory titanium (such as nickel-titanium alloy): Possesses shape memory function, automatically springing back after bending, but contains nickel; those with nickel allergies should exercise caution.
Titanium eyeglass frames are made of high-end titanium metal with a purity of ≥99%, and a density of only 4.5g/cm³, combining lightweight and high strength. This material is corrosion-resistant, hypoallergenic, and highly stable. Due to its relatively soft nature, it often employs a design with thicker lines to enhance structural strength.
