YAl2Co
metal· YAl2Co
YAl2Co is an intermetallic compound combining yttrium, aluminum, and cobalt, belonging to the class of rare-earth transition metal intermetallics. This material is primarily of research and development interest rather than established commodity use, with potential applications where high stiffness and moderate density are needed in specialized aerospace or high-temperature environments. The intermetallic structure offers controlled mechanical behavior and potential for elevated-temperature strength, making it relevant to engineers exploring alternatives to conventional superalloys or composite matrices in advanced material systems.

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.
