Custom Neodymium Magnet Specifications
Dimension
We manufacture neodymium magnets in a wide range of sizes, from miniature components for electronics to large magnets for industrial equipment. Our precision machining ensures that each magnet meets your exact dimensional tolerances, delivering consistent performance.
Coating/Plating
Neodymium magnets are prone to corrosion, so we offer a variety of protective coatings to enhance durability and aesthetics:
Nickel (Ni-Cu-Ni): The most common coating, offering excellent corrosion resistance.
Zinc: Cost-effective and suitable for less harsh environments.
Gold: Ideal for decorative or specialized applications.
Epoxy: Provides superior protection in humid or corrosive conditions.
Other Options: Including plastic or rubber coatings for specific needs.
Working Temperature
The operating temperature of a neodymium magnet depends on its grade. Standard grades (e.g., N42) operate effectively up to 80°C, while high-temperature grades (e.g., N42H, N38SH) can withstand temperatures up to 120°C–200°C. We help you choose the right grade to ensure performance in your application’s environment.
Grade Suffix | Max Operating Temperature (°C) |
|---|---|
None (N) | 80 |
M | 100 |
H | 120 |
SH | 150 |
UH | 180 |
EH | 200 |
Magnetizing Direction
We can magnetize neodymium magnets in various directions to suit your application, including:
Through the thickness

Custom Neodymium Magnets Manufacturing Process
Our rigorous, ISO-certified manufacturing process ensures the highest quality custom neodymium magnets:
Raw Material Preparation: We source high-purity neodymium, iron, and boron to create the NdFeB alloy.
Alloy Formation: Materials are melted and mixed to form a precise alloy composition.
Powder Production: The alloy is crushed into a fine powder, typically 3–7 microns in size.
Compacting: The powder is pressed into the desired shape, often with a magnetic field to align particles for optimal magnetic performance.
Sintering: The compacted parts are heated to form solid, dense magnets.
Machining: Magnets are cut or ground to precise tolerances using diamond-plated tools due to their hardness.
Magnetizing: A strong magnetic field is applied to align the magnetic domains.
Coating: Protective coatings are applied to prevent corrosion and enhance durability.
This meticulous process, supported by advanced equipment and experienced engineers, ensures consistent quality and performance.
