N55 Magnets | Ceiling N Grade NdFeB Magnet
Introduction: N55 neodymium magnets (N55 rare earth magnets)
N55 neodymium magnets are the the most powerful N series neodymium magnet. But oftentimes, N52 magnet is still considered the most powerful permanent magnet in applications for holding purpose. In the recent years, the mass production of N55 has become available at some of the top NdFeB manufacturers.
From an application point of view, N55 has a residual flux density of 14.6 kGs to 15.2 kGs, which means it’s 2-3% more powerful than N52. N55 magnets are typically used in applications with limited space but requires huge magnetic strength. In the magnetic separation, equipment makers want to bring the surface gauss of some magnetic separator models to a higher level. In such cases, N55 magnet lends itself to an ideal material. In the realm of micro magnetic engineering, the N55 grade is considered a premium material, prized for its exceptional performance characteristics.
N52 and N55 rare earth magnets
To some extent, there is a trade-off between remanence(Br) and coercivity(Hc). A higher remanence could mean a lower Hc value. In the case of N55 neodymium magnets, the magnet is theoretically more susceptible to demagnetization.
In order to increase the Br and maintain Hc, there is a difference between the production of N55 and others. Instead of using praseodymium-neodymium(PrNd) alloy, we use pure neodymium (Nd) metal to make NdFeB alloy because neodymium contributes more to the increase of Br than praseodymium. That means the cost difference between N52 and N55 is much bigger. That’s why N52 neodymium magnet still dominates the market despite the fact that N55 has been commercially available for a long time.
N55 Magnet Strength
With a magnetic pull force of up to 5300 gauss, N55 magnets outperform other neodymium magnet grades. This strength ensures they can tackle tasks that demand maximum magnetism
