· UAl4

UAl4 is an intermetallic compound in the uranium-aluminum system, representing a high-density metallic phase with significant stiffness. This material is primarily of research and specialized nuclear/aerospace interest rather than widespread commercial use, as uranium-based intermetallics are restricted by regulatory oversight and material brittleness. Engineers consider UAl4 in contexts requiring high density and stiffness in compact form, such as radiation shielding, counterweights, or specialized high-energy physics applications, though practical deployment remains limited by uranium's handling requirements, toxicity regulations, and availability constraints.

Regulatory Screening

Environmental

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.
