· Ni2MnSi

Ni2MnSi is an intermetallic compound belonging to the Heusler alloy family, characterized by a fixed stoichiometric composition of nickel, manganese, and silicon. This material is primarily studied for its ferromagnetic shape-memory properties and magnetocaloric effects, making it a research-stage compound rather than an established commercial alloy. It is investigated for applications requiring coupled magnetic and thermal responses, such as magnetic refrigeration systems and adaptive structural devices, where its ability to undergo reversible phase transformations under applied magnetic fields offers advantages over conventional shape-memory alloys or permanent magnets alone.

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.
