Custom N50 Magnets Manufacturer in China
N50 magnets are among the strongest commercially available rare earth magnets, with a maximum energy product reaching approximately 50 MGOe, N50 magnets provide significantly higher magnetic performance than standard grades such as N35, N38, N40, and N42, making them an ideal choice for demanding applications where compact size and maximum holding force are critical.
As a professional custom neodymium magnet manufacturer, we supply precision-engineered N50 magnets in various shapes, sizes, coatings, and magnetization directions to meet the requirements of global OEM and industrial customers.
What Is an N50 Magnet?
N50 Magnet refers to a high-grade sintered Neodymium Iron Boron (NdFeB) permanent magnet with a maximum energy product of approximately 50 Mega Gauss Oersteds (MGOe).
The “N” designation indicates standard temperature neodymium magnets, while “50” represents the magnet’s maximum magnetic energy density.
Compared with lower grades, N50 magnets provide:
- Stronger magnetic flux density
- Higher pull force
- Smaller magnet size for the same performance
- Better efficiency in motor and generator systems
- Improved power-to-weight ratio
