· FeFeGa

FeFeGa is an iron-gallium alloy system belonging to the ferromagnetic intermetallic family, known for exhibiting magnetostrictive properties—the ability to change shape in response to magnetic fields. This material is primarily studied for magnetostrictive actuator and sensor applications where precise magnetic-mechanical coupling is required, offering advantages over competing magnetostrictive materials like Terfenol-D in terms of cost and availability, though it typically operates under more limited temperature and field conditions.

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.
