Galfenol Magnetostrictive Material Wire Round Bar Wtih Good Tensile Strength
Fe83Ga17 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.
Composition: Fe83Ga17
Galfenol is a new type of magnetostrictive material, the main elements are Fe and Ga,this alloy is called Gafenol because it was developed by Naval Ordnance Laboratory (NOL).
Galfenol was Published in 1999, that filled the gap between traditional ferro-nickel magnetostrictive material and Terfenol-D, Galfenol with excellent stress sensitivity, mechanical and magnetostrictive properties that not available by other intelligent materials.
Galfenol has good temperature characteristics, low saturation magnetization field and high magnetostrictive strain, high magnetic conductivity, high Curie temperature characteristics, the alloy can be widely used in sensing, precision, displacement measurement, transducer, brake and other fields.
