Rare Earth Permanent Magnets

In high performance applications, rare earth permanent magnets are preferred over conventional magnets. DMRL has established process technologies for making three different classes of rare earth magnets:

SmCo5, Sm2Co17 and Nd‐Fe‐B

Different shapes and sizes of rare earth magnets for defence and aerospace applications have been made, assembled in the devices and tested.

Present Status

In an effort to ‘Make in India’ and thereby totally indigenise the production from mineral to magnet, a licensing agreement for ToT has been signed between DRDO and IREL. IREL plans to reduce the rare earth salts it sources from the beach sand by acquiring the technology established by BARC and use this indigenous raw material to produce magnets in large scale by adopting the technologies developed by DMRL.
