· JVASP-110131· YFeCo

YFeCo is an iron-cobalt-yttrium ternary alloy combining the magnetic and mechanical properties of the Fe-Co system with yttrium additions for enhanced strength and oxidation resistance. This material is primarily of research and development interest, used in high-performance magnetic applications and elevated-temperature structural applications where the base Fe-Co system requires improved creep resistance or surface oxidation protection.

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.
