Titanium gold

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

Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals. In July 2016, researchers have discovered that a titanium-gold alloy, β-Ti3Au (strictly speaking, an intermetallic), is up to 4 times harder than titanium. In the 2008 film Iron Man (2008 film), the title character wears an armor made from a titanium-gold alloy. According to actor Robert Downey Jr., who played the role of Iron Man, the suit fit him 'like a gold-titanium glove'.
