· JVASP-71647· BeCu2Re

BeCu2Re is a beryllium-copper-rhenium alloy that combines the lightweight and thermal properties of beryllium with copper's electrical conductivity and rhenium's high-temperature strength. This material is primarily of research interest for aerospace and high-performance applications where extreme temperature stability, low density, and electrical properties must be balanced, though it remains largely experimental and not widely adopted in mainstream manufacturing due to beryllium's toxicity constraints and material processing complexity.

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.
