· UAl3

UAl₃ is an intermetallic compound formed between uranium and aluminum, belonging to the uranium-aluminum system of materials studied primarily for nuclear and aerospace applications. This material is notable for its use in research contexts related to high-density fuels and structural applications where uranium's density and thermal properties are leveraged, though its practical engineering deployment is limited compared to conventional alloys due to uranium's regulatory constraints and handling requirements. Engineers would consider UAl₃ specifically for advanced nuclear fuel designs, radiation shielding applications, or specialized high-performance aerospace components where the unique density-to-modulus characteristics of uranium intermetallics provide advantages over traditional aluminum 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.
