· JVASP-64998· BeCu4Pt

BeCu4Pt is a quaternary beryllium-copper-platinum alloy that combines the lightweight and high-stiffness characteristics of beryllium with copper's electrical and thermal conductivity and platinum's corrosion resistance and stability. This is a specialized research alloy primarily of interest in aerospace, electronics, and high-performance applications where the combination of low density, high elastic modulus, and chemical inertness offers advantages over conventional beryllium-copper or copper alloys, though its platinum content makes it cost-prohibitive for many commodity applications.

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.
