· JVASP-70110· Be2CuNi

Be₂CuNi is an intermetallic compound combining beryllium, copper, and nickel, belonging to the family of high-performance metallic alloys. This material is primarily of research and specialized industrial interest, valued in aerospace and high-temperature applications where a combination of low density (from beryllium), strength, and thermal stability is critical. The alloy represents an engineering trade-off between the lightweight benefits of beryllium-based systems and the thermal/mechanical stability contributions of copper and nickel phases.

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.
