Strong Neodymium Magnets

Neodymium iron boron magnets (Neo, NdFeB or NIB magnets) are the strongest type of permanent magnets commercially available, with magnetic properties that exceed alnico and ceramic(ferrite) magnets. Sintered NdFeB magnets offer extremely high energy product for their size, they have a high magnetic remanence and much higher coercivity than other permanent magnets. They are available in a wide range of shapes, sizes and grades at relatively low prices.

Neodymium grades we carry include N42 up to the strongest neodymium magnets widely available - N52 (higher grades are available, however they are much more expensive and normally are special order only). When comparing different rare earth magnet suppliers, be sure you are comparing like grades as many carry lower grades such as N35.

In addition to multiple grades, sizes and shapes, we also carry high temperature neodymium magnets. These are listed in a separate sub-category called "HIGH TEMP NEODYMIUM MAGNETS". Grading for these will include a code at the end to denote them - for instance N42SH.
