· JVASP-35860· ErCuSn

ErCuSn is a ternary copper-tin alloy incorporating erbium, a rare earth element, to modify microstructure and mechanical properties. This material belongs to the family of rare-earth-strengthened copper alloys, which are primarily developed for applications requiring enhanced hardness, thermal stability, and creep resistance compared to conventional brasses and bronzes. The erbium addition typically improves grain refinement and precipitation hardening, making it suitable for elevated-temperature service and applications demanding superior wear resistance.

Export Control

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.
