· JVASP-37616· UCr3

UCr3 is an intermetallic compound in the uranium-chromium system, representing a high-density metal phase that combines uranium's nuclear and refractory properties with chromium's corrosion resistance. This material is primarily of research and specialized defense interest, investigated for potential use in dense structural applications where uranium-based alloys offer density and strength advantages unavailable in conventional metals. UCr3 remains largely experimental, with applications limited to specialized military, nuclear, or high-performance research contexts where its unique density and refractory characteristics justify the handling complexity associated with uranium-bearing materials.

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.
