BeCu4Sn
metal· JVASP-67838· BeCu4Sn
BeCu4Sn is a beryllium-copper-tin alloy that belongs to the family of high-strength copper-based materials, combining the exceptional stiffness and electrical conductivity of beryllium copper with tin additions for enhanced wear resistance and damping characteristics. This alloy is found in precision mechanical components, electrical connectors, and spring applications where a combination of high strength, excellent fatigue resistance, and controlled electrical properties is required. The tin addition typically improves machinability and reduces galling compared to standard beryllium-copper alloys, making it particularly valuable in applications demanding tight tolerances and repeated mechanical cycling.

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.
