Custom N38 Magnets Manufacturer in China
N38 Magnet is a high-performance neodymium iron boron (NdFeB) magnet grade that offers an excellent balance between magnetic strength, cost efficiency, and manufacturing flexibility. Compared with lower grades such as N35 and N37, N38 magnets provide stronger magnetic performance while remaining a cost-effective solution for a wide range of industrial and commercial applications.
We manufacture custom N38 neodymium magnets in various shapes, sizes, coatings, and magnetization directions to meet the requirements of global OEMs, distributors, and industrial equipment manufacturers.
What Is an N38 Magnet?
N38 refers to the magnetic grade of a neodymium magnet. The number “38” indicates the magnet’s maximum energy product (BHmax), approximately 38 MGOe (Mega Gauss Oersteds).
N38 magnets belong to the permanent rare earth magnet family and are known for their:
- Strong magnetic force
- Compact size
- High energy density
- Excellent durability
- Long service life
- Cost-effective performance
These characteristics make N38 magnets ideal for applications requiring stronger holding force than N35 magnets while maintaining reasonable production costs.
