· Ni2MnSi0.2Sn0.8

Ni2MnSi0.2Sn0.8 is a quaternary Heusler-class intermetallic compound combining nickel, manganese, and silicon-tin substitution on the X-site. This material belongs to the family of shape-memory alloys (SMAs) and magnetic shape-memory alloys (MSMAs), which exhibit reversible martensitic phase transformations often coupled with ferromagnetic behavior. The silicon-tin partial substitution (0.2/0.8 ratio) modifies the electronic structure and transformation temperatures compared to binary or ternary Heusler systems, making it relevant for research into tunable magnetostructural properties. While primarily an experimental/developmental composition, Ni-Mn-based Heuslers are investigated for applications requiring the combination of shape-memory recovery, magnetic response, and thermal stability.

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.
