Titanium-Gold Alloy

Titanium-Gold Alloy is a special metal alloy used by Tony Stark as the base armor for his Iron Man Armors. The Alloy features two metallic elements, Gold and Titanium.

The Mark III was the first armor to use this Alloy for its plating. It is presumed that this Alloy can resist the build up of ice when flying at high altitudes in the atmosphere, compared to the Chromed Titanium Steel Alloy which easily froze when the Mark II reached a certain point in the atmosphere during its test flight by Tony.
