metal

· JVASP-38637· NiAu3

NiAu3 is an intermetallic compound composed of nickel and gold, belonging to the class of ordered metallic phases with a fixed stoichiometric ratio. This material is primarily of interest in research and specialized applications due to its high density and potential for wear resistance and corrosion protection in harsh environments. Its use in production applications is limited compared to solid-solution alloys, but it has been explored for electrical contacts, bonding layers in microelectronics, and thin-film coatings where the unique phase stability and noble-metal content provide advantages in demanding conditions.
