NdFeB Sintered Magnets
Provide highest energy products available in permanent magnet material.
· Extremely stable when exposed to stray electromagnetic fields or
repulsive forces generated by another permanent magnet.
· Plentiful, non-strategic raw materials insure product availability.
· Variety range of sizes and geometries available
· Precise calibration is achievable for the most demanding applications.
· Available in isostatically pressed billets for cutting or fabrication.
· High energy products allow volume of material used to be minimize.
· Highly efficient material allows for size and weight reductions for products. |
