· JVASP-65052· YBeCo4

YBeCo4 is an intermetallic compound combining yttrium, beryllium, and cobalt, belonging to the rare-earth transition-metal alloy family. This material is primarily of research interest for applications requiring specific combinations of lightweight properties and magnetic or electronic characteristics, though industrial deployment remains limited. Engineers would evaluate it in specialized aerospace, defense, or advanced material science contexts where the unique yttrium-cobalt-beryllium interaction offers performance advantages over conventional alloys.

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.
