· JVASP-9620· YAl8Fe4

YAl8Fe4 is an intermetallic compound combining yttrium, aluminum, and iron—a material class valued for combining light weight with high stiffness and thermal stability. This compound is primarily of research and specialized industrial interest, used in applications requiring excellent rigidity-to-weight ratios and resistance to thermal cycling, such as aerospace structural reinforcement, high-temperature tooling, and advanced composite matrices. Engineers select YAl8Fe4-based materials when conventional aluminum alloys lack sufficient stiffness or thermal performance, though availability and cost typically limit adoption to demanding applications where performance justifies the premium.

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.
