Titanium Advantages In Eyewear

Titanium is valued for its high strength, toughness, low density and corrosion resistance, which supports its use in aerospace, sports equipment and premium automotive applications. The metal exhibits a deep dark sheen that has been documented in consumer goods. Recently, this material has been adopted in the eyewear industry. In this article, we examine the advantages of titanium in eyewear products.

Advantages of Titanium in Eyewear

The combination of titanium’s distinct appearance and its physical properties benefits users with active lifestyles. The titanium wire frame material is suitable for incorporating thicker lenses. Another advantage is its hypoallergenic property; consequently, it does not cause skin irritation, in contrast to many nickel-containing metals.

Typically, three types of titanium are used in eyeglass frames: pure titanium, beta titanium and Memory Metal. The initial frames were produced from pure titanium and achieved commercial acceptance. Subsequently, beta titanium and then Memory Metal established distinct niches in this market.

Beta titanium is an alloy primarily composed of titanium with vanadium and aluminium added for improved strength and toughness. Given its high strength-to-modulus ratio, this alloy imparts elasticity to the frame, thereby maintaining stability during prolonged use. Beta titanium is strong, durable, lightweight, flexible, hypoallergenic and corrosion resistant.

Memory Metal is an alloy consisting of approximately 50% titanium and 50% nickel. It exhibits a significant degree of flexibility. Eyewear frames manufactured from Memory Metal can be bent without fracturing and subsequently return to their original shape, even following extensive deformation.

Eyewear produced from flexible titanium, whether from pure titanium, beta titanium or Memory Metal, represents a recent development in eyeglass frame production. It is employed by individuals with active lifestyles, particularly for children’s and sports applications. It is suitable for users requiring lightweight frames.
