MnNi
metal· MnNi
MnNi is an intermetallic compound combining manganese and nickel, belonging to the family of binary transition metal alloys. This material system is primarily investigated in research contexts for its potential in magnetic applications, shape-memory alloys, and high-strength structural applications where the combination of these two elements offers unique phase stability and mechanical behavior. Its industrial adoption remains limited, with most development focused on fundamental material science studies and exploration of specialized applications in magnetostrictive devices and advanced alloy design.

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.
