· JVASP-21696· Y2Al9Co3

Y2Al9Co3 is an intermetallic compound combining yttrium, aluminum, and cobalt, belonging to the family of rare-earth aluminum metal systems. This material is primarily of research and development interest rather than established industrial production, with potential applications in high-temperature structural applications where the combination of light-weight aluminum with rare-earth strengthening and cobalt's refractory properties offers benefits. Engineers would consider this material class when seeking alternatives to conventional superalloys or composite reinforcements, particularly in aerospace or thermal management contexts where material density and high-temperature stability are competing design drivers.

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.
