· JVASP-9417· YAl4Ni

YAl4Ni is an intermetallic compound combining yttrium, aluminum, and nickel, belonging to the family of rare-earth transition metal aluminides. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in high-temperature structural materials and advanced aerospace components where lightweight strength and thermal stability are critical.

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.
