· CoPt3

CoPt3 is an intermetallic compound combining cobalt and platinum in a 1:3 ratio, belonging to the class of ordered metallic intermetallics known for high strength and exceptional hardness. This material is primarily investigated in research and advanced aerospace contexts, where its combination of structural rigidity and resistance to deformation at elevated temperatures makes it attractive for high-performance applications. CoPt3 is also of significant interest in magnetic materials research and thin-film device engineering due to cobalt-platinum alloys' well-established magnetic ordering and potential for use in permanent magnets and spintronic applications.

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.
