· JVASP-153287· Be12Au

Be₁₂Au is an intermetallic compound combining beryllium and gold, belonging to the family of lightweight metallic compounds with potential for high-performance applications. This material is primarily of research and specialized industrial interest rather than commoditized use, valued for its combination of low density with metallic bonding characteristics that could enable weight-critical or high-temperature applications. The beryllium-gold system is explored in aerospace and materials science research contexts where reducing structural mass while maintaining thermal or electrical properties is critical.

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.
