· JVASP-65274· BeCu4Sb

BeCu4Sb is a beryllium-copper intermetallic compound containing antimony, belonging to the family of beryllium-copper alloys that are valued for high strength and thermal conductivity. This material is primarily of research interest for applications requiring lightweight, high-strength performance combined with specific electronic or thermal properties; beryllium-copper alloys more broadly are used in aerospace, electronics, and precision instrumentation where the combination of strength, hardness, and thermal management is critical.

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.
