· JVASP-141276· Dy2Fe17C3

Dy2Fe17C3 is an intermetallic compound combining dysprosium (a rare-earth element) with iron and carbon, forming a ceramic-metallic composite material in the Fe17C3 family. This material is primarily of research interest for permanent magnet and high-temperature structural applications, where the rare-earth dysprosium addition enhances magnetic coercivity and thermal stability—properties valuable in demanding aerospace and energy conversion systems. Engineers consider this compound when conventional ferromagnetic alloys or standard rare-earth magnets cannot meet extreme temperature or high-field requirements, though processing complexity and raw material costs typically limit it to specialized, high-performance applications rather than commodity use.

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.
