· Co0.25Ni1.75MnSn

Co0.25Ni1.75MnSn is a quaternary Heusler alloy, a metallic intermetallic compound combining cobalt, nickel, manganese, and tin in a precise stoichiometric ratio. This material is primarily of research and emerging technological interest rather than established industrial use, belonging to the family of magnetic shape-memory alloys (MSMAs) and half-metals that exhibit ferromagnetic behavior with potential for high spin polarization. The Co–Ni–Mn–Sn system is studied for applications requiring reversible magnetic-field-induced strain, making it relevant to actuators, magnetic refrigeration, and magnetocaloric devices where conventional ferromagnetic steels fall short.

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.
