· NiMnGa

NiMnGa is a ferromagnetic shape-memory alloy (SMA) based on nickel, manganese, and gallium, belonging to the Heusler alloy family known for martensitic phase transformations. This material exhibits the shape-memory effect and magnetic-field-induced strain (MFIS), enabling actuation and control through magnetic stimulation rather than thermal or mechanical means. NiMnGa is primarily investigated in research and specialized aerospace/robotics applications where magnetic actuation, adaptive damping, and novel sensing capabilities offer advantages over conventional SMAs; it remains less commercialized than NiTi SMAs but represents a frontier material for next-generation smart structures and magnetically-driven actuators.

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.
