Product Description

Galfenol Magnetostrictive Material Fe83Ga17 with Mechanical Properties

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 exhibits a unique combination of mechanical and magnetostrictive (magnetic) properties that legacy smart materials do not.

In addition, the Galfenol Public Release provides a primer on current processing techniques and standard forms, compositions produced by xunshi, and unique shapes that have been fabricated using Galfenol alloys.


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.


It should be noted that research is on-going in developing new processing methods to fabricate Galfenol components. This includes rolling the material into sheet form, wire drawing, and additive manufacturing. XUNSHI is always on the look-out for possible partners to help advance these next-generation manufacturing methods. Please feel free to contact us for such requirements if you are interested.
