Description:

RARE-EARTH-FREE PERMANENT MAGNETIC MATERIAL BASED ON FeNi

INV-15016

INVENTORS: Laura Lewis; Jeffrey Shield; Katayun Barmak

Description       

In prior-art, most of the well known magnetic materials (including super-magnets) are rare-earth based. Though the existing magnets have a high strength, the rare earth materials producing such magnets have a limited availability and are thus expensive. Due to this limitation, the prior-art seems to have a strong unmet need to develop/identify new materials for high performance permanent magnets.  This invention relates to development and use of novel, FeNi based rare-earth-free permanent magnetic materials, having potential to overcome prior-art limitations and/or unmet needs.

 

Value Proposition

The magnetic material:

•Contains particles having nanometer size range

•Possesses high magnetization and high anisotropy

•Is simple to process and handle as compared to conventional materials

•Is suitable for use as a replacement for lower-end (isotropic) rare-earth-containing magnets

•Offers a life-cycle sustainability as well as corrosion resistance

•Is substantially or essentially free of rare earth elements such as neodymium and samarium

•Has a better availability, and therefore less expensive as compared to conventional materials

•Comprises a nano-structured alloy composition containing an iron-nickel alloy substituted with doping elements

•Is useful for producing magnetic structures having variety of commercial applications such as motors, generators, and other electromechanical and electronic devices
