MnAu4
metalMnAu4 is an intermetallic compound combining manganese and gold in a 1:4 atomic ratio, belonging to the class of noble metal intermetallics. This material exhibits high density and intermediate elastic stiffness, making it of interest primarily in research contexts for applications requiring wear resistance, corrosion immunity, or specialized electronic properties that leverage gold's nobility combined with manganese's magnetic characteristics. While not widely deployed in mass-production engineering, MnAu intermetallics are studied for high-performance wear coatings, dental and biomedical alloys, and electronic interconnect applications where gold's chemical inertness and the compound's hardness offer advantages over conventional alternatives.
