Properties
When exposed to air, titanium forms a highly durable protective oxide layer, which makes it corrosion-resistant in many media. Its high strength to density ratio is of particular note. It gives steel a high toughness, robustness and ductility. Titanium alloys are lightweight and very durable.
Applications
Titanium is mainly used as an alloying element for steel. In electronics, it serves as a coating metal. Titanium alloys are used in aerospace construction and outdoor equipment as structural components, as well as in medicine as bone substitutes.
