UAl
metal· JVASP-156739· UAl
UAl is an intermetallic compound composed of uranium and aluminum, belonging to the uranium-aluminum binary system. This material is primarily of research and specialized industrial interest, used in nuclear fuel applications and advanced metallurgical studies where the unique properties of uranium-based intermetallics offer advantages in high-temperature or neutron-rich environments. Engineers consider UAl for applications requiring the combined density and thermal properties of uranium with aluminum's lighter alloying contribution, though its use is strictly regulated and limited to nuclear, aerospace, and defense sectors where such materials are qualified.

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.
