Introduction of FeGa Alloy wire(Galfenol Wire):
FeGa Alloy(Galfenol) is a magnetostrictive alloy comprised primarily of the elements iron (Fe) and gallium (Ga).
It was hypothesized that other magnetostrictive alloys had to exist that combined the mechanical robustness of Ni and the giant magnetostrictive response of Terfenol-D.
Galfenol exhibits a unique combination of mechanical and magnetostrictive (magnetic) properties that legacy smart materials do not.
