· JVASP-23827· YbCoB4

YbCoB4 is a rare-earth cobalt boride intermetallic compound combining ytterbium, cobalt, and boron. This is a research material studied primarily for its potential magnetic and electronic properties rather than a commercial engineering material; compounds in the rare-earth transition-metal boride family are investigated for applications requiring specialized magnetic behavior, hard coatings, or high-temperature phases, though YbCoB4 specifically remains in the experimental phase with limited industrial deployment.

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.
