· Al4 Co2 Y2

Al4Co2Y2 is an intermetallic compound combining aluminum, cobalt, and yttrium—a research-phase material belonging to the family of rare-earth-bearing metallic compounds with semiconductor properties. This ternary system is primarily of academic and exploratory interest, investigated for potential applications in high-temperature structural materials, magnetic systems, or advanced electronic devices where the combination of metallic bonding and rare-earth elements may offer unique electronic behavior. The material remains largely in the research domain rather than established industrial production, making it relevant for engineers exploring next-generation alloy concepts or working on emerging technologies in aerospace, electronics, or materials science research.

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.
