Titanium gold

In metallurgy, titanium gold (Ti-Au or Au-Ti) refers to an alloy consisting of gold and titanium. Such alloys are used in dentistry,[1][2] ceramics and jewelry.[3] Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength and hardness than either of its constituent metals.

In July 2016, researchers have discovered that a titanium-gold alloy, β-Ti3Au (strictly speaking, an intermetallic), is, in fact, up to 4 times stronger than most steels.[4]

In popular culture

In the 2008 film Iron Man (2008 film), the title character wears an armor made from a titanium-gold alloy.[5][6] According to actor Robert Downey Jr., who played the role of Iron Man, the suit fit him "like a gold-titanium glove".[7]
