· JVASP-37809· BeAu3

BeAu₃ is an intermetallic compound composed of beryllium and gold, belonging to the class of precious metal intermetallics. This is a research-stage material with limited commercial deployment; it represents an experimental composition within the beryllium-gold phase diagram studied for its potential in specialized applications requiring combined properties of both constituents. The material is notable for its extreme density and potential for applications where gold's chemical inertness and beryllium's lightweight character might be simultaneously beneficial, though practical use remains constrained by beryllium's toxicity hazards, high cost, and challenging manufacturing requirements.

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.
