Custom N55 Magnets Manufacturer in China
N55 magnet is one of the strongest commercially available neodymium magnet grades in the market today. Manufactured from premium rare earth NdFeB material, N55 neodymium magnets provide exceptional magnetic force, compact size, and outstanding energy density for high-performance industrial applications.
We supply custom N55 magnets in multiple shapes, coatings, tolerances, and magnetization directions to meet demanding engineering and manufacturing requirements worldwide.
What Is an N55 Magnet?
An N55 magnet is a high-grade neodymium iron boron (NdFeB) permanent magnet with a maximum energy product of approximately 55 MGOe.
Compared with lower grades such as N35, N42, or N52, N55 magnets deliver:
- Stronger magnetic pull force
- Higher magnetic flux density
- Better performance in compact assemblies
- Reduced magnet size requirements
- Higher efficiency in precision devices
N55 magnets are ideal for industries requiring maximum magnetic strength in limited space.
Advantages of N55 Magnets
- Ultra-high magnetic strength for compact product designs
- Higher magnetic performance than many standard NdFeB grades
- Ideal for miniaturization in motors, sensors, and magnetic assemblies
- Custom shapes and sizes available according to drawings or samples
- Multiple coating options for corrosion protection
- Flexible magnetization directions, including axial, diametrical, radial, and multi-pole magnetization

FAQs About N55 Magnets
Yes, N55 is among the strongest commercially available neodymium magnet grades for industrial applications.
Standard N55 magnets are usually recommended for applications up to 80°C. If your application requires higher working temperatures, we can recommend high-temperature NdFeB grades with better coercivity.
Yes, in the same size and structure, an N55 magnet can often provide stronger magnetic performance than an N52 magnet.
Yes. We provide OEM and custom manufacturing services based on drawings, specifications, or samples.
Ni-Cu-Ni is the most common coating for N55 neodymium magnets. For humid or corrosive environments, epoxy, parylene, or other protective coatings may be better choices.
No. Finished neodymium magnets are hard and brittle. Drilling, cutting, or grinding them after magnetization may cause cracking, chipping, coating damage, and safety risks. If you need holes, grooves, or special shapes, please customize them before production.
Please provide magnet size, shape, grade, coating, quantity, tolerance, magnetization direction, application, and working temperature. A drawing or sample will help us quote more accurately.
