Dy2Co17
metal· JVASP-154910· Dy2Co17
Dy2Co17 is an intermetallic compound in the rare-earth cobalt family, combining dysprosium (a heavy rare-earth element) with cobalt in a fixed stoichiometric ratio. This material is primarily of research and specialized industrial interest due to its strong permanent magnetic properties and high Curie temperature, making it relevant for high-temperature magnetic applications where standard ferromagnetic alloys lose effectiveness. Dy2Co17 compounds are investigated for permanent magnet systems, particularly in aerospace and energy sectors, though they remain less common than competing rare-earth cobalt magnets (such as SmCo5) due to processing complexity and cost considerations.

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.
