titanium is a pure material present in nature. Its unique features, like mechanical and corrosion resistance, make it possible to design particularly sturdy, lightweight and hypoallergenic frames (nickel free), also thanks to the composition of high performing alloys with other metals. Luxottica uses alloys with pure titanium (2nd degree). Titanium frames are particularly suitable for people suffering from nickel allergie.
its high resistance to chemical agents ensures top performance even under extreme conditions. It has an excellent abrasion and scratch resistance. Mainly used for components of the frames.
