· Ni2MnGa

Ni₂MnGa is a ferromagnetic shape-memory alloy (FSMA) based on the Heusler intermetallic compound family, characterized by its ability to undergo reversible martensitic transformation triggered by magnetic fields rather than temperature alone. This material is primarily investigated in research and emerging applications where magnetic actuation, energy harvesting, and adaptive structural response are critical, offering advantages over conventional thermoelastic shape-memory alloys by enabling remote, contactless control of shape change.

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.
