Reance SF™ (U.S. Patent# 6,707,361) is Electrodyne’s new super flexible neodymium iron boron magnet material.

Aside from being a very high energy magnet material, (up to 5.0MGOe), Reance SF™ is extremely flexible as it can be bent to very tight radiuses without cracking, breaking, or losing any of its magnetic power. Reance SF™ is even elastic (another first).

With a total elongation of up to 250%, Reance SF™ creates a new dimension in magnet design and application.

Do you need an ultra thin magnet for a sensor or other thickness critical application? Reance SF™ is available down to .008”, setting another new standard for high energy magnets.

As with all Electrodyne products, our technical staff is available to discuss the production of specialized compounds and magnetizing fixtures to meet your requirements.
