Titanium– the hottest metal frame material today is titanium. Titanium is an extremely strong, lightweight metal used to manufacture a wide variety of products from
aircraft and satellites to golf clubs and cameras. Titanium frames may be composed of pure titanium or titanium alloys (sometimes called "beta titanium") that contain small amounts of vanadium, aluminum, and other metals to increase flexibility. Titanium frames are very light and durable. The strength of titanium allows manufacturers to create frames with very thin, minimalistic designs.
