Custom N52 Magnets Manufacturer in China
N52 magnet is one of the highest energy grades of sintered neodymium iron boron magnets, offering exceptional magnetic strength in a compact size. With high remanence and strong holding force, N52 neodymium magnets are widely used in motors, sensors, magnetic assemblies, electronics, tools, fixtures and high-performance industrial applications.
As a custom N52 magnet supplier, we manufacture N52 NdFeB magnets in disc, block, ring, cylinder, arc, segment, countersunk and special shapes according to your drawings or samples. Different coatings, magnetization directions and tolerances are available to meet your application requirements.
What Is an N52 Magnet?
An N52 magnet is a high-performance neodymium magnet grade with a maximum energy product of approximately 50 to 53 MGOe. Compared with lower grades such as N35, N42 or N48, N52 magnets can provide stronger magnetic force in the same volume, making them suitable for applications where space is limited but magnetic strength is critical.
N52 magnets are ideal when you need:
- Higher holding force in a smaller magnet size
- Compact magnetic assemblies
- Strong pull force for industrial fixing or mounting
- High magnetic flux for sensors and magnetic couplings
- Custom magnet solutions for OEM products

Key Features of N52 Magnets
Ultra-Strong Magnetic Force
N52 magnets provide one of the highest magnetic strengths available in commercial permanent magnets.
Compact Yet Powerful
Smaller N52 magnets can achieve the same holding force as larger lower-grade magnets, helping reduce product size and weight.
Excellent Performance
Suitable for precision industrial applications requiring high magnetic energy density.
Multiple Customization Options
Available in custom dimensions, tolerances, coatings, and magnetization orientations.
Corrosion Resistance
Optional protective coatings improve durability in humid and harsh environments.

FAQ About N52 Magnets
N52 refers to a high-performance grade of neodymium magnet. The number indicates its maximum energy product range, which is approximately 50 to 53 MGOe.
N52 is one of the strongest commonly available grades of sintered neodymium magnets. It provides very high magnetic strength in a compact size.
Standard N52 magnets usually work up to 80°C. If your application requires higher operating temperature, high-temperature grades such as N52M or N52H may be more suitable.
Yes. We can produce custom N52 magnets according to your drawings, samples or technical requirements, including custom shape, size, coating, tolerance and magnetization direction.
Ni-Cu-Ni is the most common coating for N52 magnets. For humid or corrosive environments, epoxy coating or other protective solutions may be recommended.
