FeAu3

FeAu3 is an intermetallic compound composed of iron and gold in a 1:3 stoichiometric ratio, belonging to the class of ordered metallic compounds with a defined crystal structure. This material combines the properties of both constituent elements—iron's strength and gold's corrosion resistance and stability—making it of particular interest in specialized applications requiring both durability and chemical inertness. FeAu3 is primarily explored in research contexts for jewelry alloys, wear-resistant coatings, and electronics applications where the noble metal character of gold enhances corrosion resistance while iron provides structural support; its high density and intermetallic nature also position it for consideration in applications requiring stiffness and dimensional stability.
