Si4 Ni2 Dy2
metal· Si4 Ni2 Dy2
Si₄Ni₂Dy₂ is an intermetallic compound combining silicon, nickel, and dysprosium (a rare earth element). This is a research-phase material rather than a production alloy; such ternary intermetallics are investigated for their potential to combine the thermal stability of silicon-based compounds with the magnetic and strengthening properties that rare earth elements provide. Interest in this composition family typically centers on high-temperature structural applications or magnetic device applications where conventional alloys reach performance limits.

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.
