· JVASP-70810· BeCo4Sb

BeCo4Sb is a beryllium-cobalt-antimony intermetallic compound belonging to the rare-earth-free metallic alloy family. This material is primarily of research interest rather than established industrial production, with potential applications in high-performance aerospace and electronics where its unique combination of low density and electronic properties could offer advantages over conventional alloys. The beryllium base provides light weight while the cobalt-antimony combination contributes to enhanced strength and potentially useful electrical or magnetic characteristics.

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.
