Neodymium Rectangular Bar

Neodymium magnets (NdFeB), are high-performance permanent magnets constructed from an alloy of neodymium, iron and boron. They are used in applications where the strongest magnetic force is required from the smallest possible volume of magnet material. Even small neodymium magnets have a surprising amount of magnetic force, and they are capable of lifting in excess of 1,000 times their own weight. Neodymium magnets are used for magnetic therapy, crafts, jewelry, speakers, figurines, table top games, models and magnetic fishing. Neodymium magnets are the strongest magnets, and they are available in discs, blocks, arcs, spheres and trapezoid shapes. They can be supplied with a number of fixing options including countersunk holes for screw fixing and with 3M 468 self-adhesive.

Neodymium magnets, or to give them their full title, neodymium-iron-boron (NdFeb) magnets are part of the permanent rare earth family of magnets and are renowned for being the strongest permanent magnets in the world. They are the strongest because of their high remanence (the amount of magnetism retained by the material, once magnetised) and their high coercivity (resistance to being demagnetised).

Because of their magnetic properties, neodymium magnets can be manufactured as small as 1mm diameter x 1mm thick and still maintain notable performance. This has helped support much advancement in consumer applications and heavy engineering alike during the last 40 years.

Commercially available grades are denoted by the letter ‘N’ followed by a numerical suffix ranging from the weakest N35 to the strongest N52. As standard grade neodymium magnets have a maximum operating temperature of 80 degrees Celsius, we also produce a range of high temperature grades, denoted by the letters M, H, SH, UH, EH or AH after the grade, which can maintain their performance in temperatures up to 230 degrees Celsius.
