· JVASP-21543· DyAl8Fe4

DyAl8Fe4 is an intermetallic compound combining dysprosium, aluminum, and iron—a rare-earth metal system designed to achieve specific combinations of stiffness and moderate density. This material belongs to the family of rare-earth aluminum intermetallics, which are primarily explored in research and advanced aerospace contexts where weight savings and thermal stability are critical; industrial adoption remains limited, with applications concentrated in high-performance aerospace structures, thermal management systems, and specialized magnetic or structural applications where the unique phase stability of rare-earth elements provides advantages over conventional aluminum or steel alloys.

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.
