MnAu
metal· MnAu
MnAu is an intermetallic compound combining manganese and gold, belonging to the family of binary metal alloys that exhibit ordered crystalline structures. This material is primarily investigated in research and materials science contexts for applications requiring a combination of magnetic properties (from manganese) and chemical stability (from gold), rather than as a widely commercialized engineering material. The MnAu system is of particular interest in magnetism research, magnetic recording technologies, and potentially in high-performance applications where corrosion resistance and specific magnetic behavior must be balanced.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
