ceramic

· JVASP-156750· NdDy

NdDy is a ceramic compound composed of neodymium and dysprosium, rare-earth oxides or intermetallic phases used primarily in high-performance magnetic and thermal applications. This material is notable in permanent magnet systems and high-temperature structural ceramics where the combined rare-earth elements provide enhanced magnetic properties, thermal stability, and oxidation resistance compared to single rare-earth alternatives. NdDy compositions are engineered for demanding aerospace, energy conversion, and specialized electronics applications where cost-performance trade-offs favor rare-earth strengthening over conventional ceramics.

Regulatory Screening

Environmental

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.
