· MnAu2

MnAu₂ is an intermetallic compound combining manganese and gold in a 1:2 stoichiometric ratio, belonging to the class of binary metallic intermetallics. This material exhibits a dense crystal structure and moderately high bulk stiffness, making it of interest primarily in research contexts for specialized applications requiring the unique combination of manganese's magnetic properties with gold's chemical nobility and stability. Industrial applications are limited and specialized, as the high cost of gold and the brittle nature typical of intermetallics restrict its use to niche sectors such as advanced magnetic devices, wear-resistant coatings, or high-temperature oxidation-resistant applications where the synergistic properties of both elements justify the material expense.

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.
