What is The Difference Between N35 And N52 Magnets?

Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.

Neodymium-iron-boron (NdFeB) magnets are the most powerful commercialized permanent magnets available today, with maximum energy products ranging from 35 MGOe to 52 MGOe. NdFeB is the third generation of permanent magnet developed in the 1980s with high resistance to demagnetization. It has a combination of very high remanence and coercivity and comes with a wide range of grades, sizes, and shapes. The maximum operation is up to 220-degree centigrade.

With its excellent magnetic characteristics, abundant raw material, and relatively low prices, Nd-Fe-B offers more flexibility in designing new or replacing the traditional magnet materials such as ceramic magnet, Alnico magnet, and Sm-Co to achieve high efficiency, low cost, and more compact devices.

The N52 magnets are the highest grade of permanent neodymium magnets on the market. All the N52 neodymium magnets provide the same 52 MGOe (science stuff) as the High Energy Rare Earth Magnets no matter their sizes or shapes or 1.44 Tesla as the Magnetic Flux Density (more Science stuff). Of course, the actual holding force increase as the size of the magnet increases. In Comparison, a grade52 magnet neodymium super magnet is roughly 14% stronger than an N45 neodymium magnet and 60% stronger than other neodymium magnets when their shape and dimensions are the same.

N52 neodymium magnets are expertly engineered & precision-crafted for tight tolerances and powerful performance. Rare earth magnets in grade N52 are more powerful than grade N35 magnets of the same size.
