· BeAu2

BeAu2 is an intermetallic compound composed of beryllium and gold, belonging to the class of metal-based intermetallics that combine properties from both constituent elements. This material is primarily of research and specialized industrial interest rather than a high-volume commodity, with applications in precision electronics, aerospace components, and specialized bearing systems where its unique combination of low density and high stiffness provides advantages over conventional alloys. BeAu2 is notable for applications requiring lightweight construction with excellent dimensional stability and thermal properties, though its use is constrained by beryllium's toxicity concerns, high material cost, and the specialized manufacturing expertise required.

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.
