Titanium

Titanium is a popular material for eyeglass frames because of its many benefits, including:
Strength
Titanium is one of the strongest metals and has the best strength-to-weight ratio of any metal. Titanium frames are durable and can withstand daily wear and tear.

Lightweight
Despite its strength, titanium is lightweight, making it comfortable to wear for long periods of time.

Corrosion-resistant
Titanium resists corrosion from sweat and moisture, making it a good choice for active people or those who live in humid climates.

Hypoallergenic
Titanium is non-toxic and hypoallergenic, reducing the risk of allergic reactions.

Memory metal
Titanium can be made into a memory metal, meaning it can bend and return to its original shape.

Lens protection
Titanium bevels can act as protective chambers to prevent chips and cracks.

Style
Titanium frames come in a variety of styles and have a polished metallic look.

Titanium is the fourth most abundant material in the Earth’s crust, but it’s expensive to produce because of the special processes required to extract and shape it.
