· JVASP-34966· YAl8Cr4

YAl8Cr4 is an experimental intermetallic compound combining yttrium, aluminum, and chromium, representing a research-phase material in the refractory metal alloy family. While not yet established in mainstream engineering production, this composition targets high-temperature applications where conventional superalloys reach their limits, with potential relevance to aerospace propulsion, thermal barriers, and extreme-environment structural components. The yttrium addition typically improves oxidation resistance and grain stability, while chromium enhances strength and corrosion protection—making this alloy family of interest to researchers developing next-generation materials for hypersonic vehicles and advanced turbomachinery, though engineering adoption requires further development and qualification.

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.
