Flexible Magnets

Reance F™ Flexible Neodymium Rare Earth Magnets

Reance™ is Electrodyne’s trade name for its patented line of bonded neodymium iron boron magnets. Revolutionary Reance™ opens new possibilities for the design and engineering of new or existing products.

Reance F™ (U.S. Patent No. 4,873,504), for years, has set the standard for flexible neodymium iron boron magnets. Available in energy products up to 6.5MGOe, Reance F™ offers magnetic force many times greater than that of conventional flexible magnet materials.

Due to its flexible nature, Reance F™ rare earth magnets can be easily slit, drilled, punched or die-cut to customer specification, allowing for economical prototyping and production quantities through the use of low cost tooling techniques. Used in such products as graphic reproduction machines and guitar pickups, Reance F™ provides high magnetic force in a versatile flexible form.

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