metal

· JVASP-100739· MnAu3

MnAu3 is an intermetallic compound composed of manganese and gold, belonging to the family of noble-metal intermetallics. This material exhibits the high density and chemical stability characteristic of gold-based alloys, combined with manganese's influence on hardness and corrosion resistance. While primarily of research interest rather than high-volume production, MnAu3 and similar manganese-gold phases are investigated for applications requiring exceptional corrosion resistance, wear resistance, and stability in demanding chemical environments where the cost of gold content is justified.
