Titanium and Its Alloys

Titanium and its alloys are considered relatively new engineering metals, as their application as structural metals began in 1952. Titanium alloys are highly attractive due to properties such as a high strength-to-weight ratio, excellent performance at high temperatures up to about, and outstanding corrosion resistance, especially in oxidizing acid environments and in most natural environments. Unfortunately, Titanium and its alloys are more expensive than conventional metals. This is because extracting them from their ores is challenging, and complex melting techniques must be used for their production. The high cost of producing Titanium alloys is due to the severe reactions and strong affinity they have with interstitial metals such as Oxygen, Nitrogen, Hydrogen, and Carbon. Nonetheless, Titanium and its alloys compete well with other metals in applications where their specific properties are required. For example, the high strength-to-weight ratio and excellent high-temperature properties of Titanium alloys are of primary importance in the aerospace industry. Titanium’s excellent corrosion resistance makes it one of the most useful alloys in the chemical and food industries. The search for new applications for Titanium and its alloys continues, and new uses have been discovered so far.
