· Au1 Er1 Ni4

Au1Er1Ni4 is an intermetallic compound combining gold, erbium, and nickel in a 1:1:4 atomic ratio. This is a research-phase material in the rare-earth intermetallic family, likely explored for its potential combination of thermal, magnetic, or electronic properties that arise from the interaction between the noble metal (Au), rare-earth element (Er), and transition metal (Ni) constituents. Such ternary intermetallics are investigated in materials science for specialized applications where conventional alloys cannot meet performance demands, though industrial adoption remains limited and material behavior is not yet standardized.

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.
