Sintered NdFeB
Sintered NdFeB, Neodymium Magnets (NdFeB), Sintered Neodymium-iron-boron, Licensed Rare Earth Neo Magnets, Nd Permanent Magnets China Supplier
Our Sintered NdFeB & Neodymium Capabilities:
- Neodymium is the strongest available magnet alloy at up to 52MGOe. The use of Neodymium results in smaller, more cost-effective magnet solutions replacing older materials like Alnico and Ceramic in many applications.
- MPCO can help optimize performance and cost with Neo magnets in grades from 33 to 52MGOe and operating temperatures up to 230°C/446°F.
- Customized Neodymium magnets also available.

Available Grades of Neo:
Sintered NdFeB Magnets
Many grades of Neodymium exist to support a variety of industrial and commercial applications. The range of Neo grades is typically 33 to 52 MGOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance. Click download >> MPCO neodymium grades and demagnetisation curves data.PDF
Corrosion Resistance:
Neodymium magnets have poor resistance to corrosion and they can also corrode from the inside out if proper pre-treatment processes are not followed. Oftentimes a multi-layer Nickel-Copper-Nickel plating is applied, but this may not be sufficient for all applications.
Temperature Effects:
Neodymium magnets are very susceptible to elevated operating temperatures and the application requirements should be considered before selecting a particular grade of Neo.
Magnetization Options:
Although most commercial magnets are anistropic, which means they have a preferred direction of magnetization, various pole configurations can be achieved without conflicting with a Neodymium Magnet’s orientation.
Handling and Storage of Neodymium Magnets:
Neodymium Magnets are very strong and brittle, requiring appropriate handling and packing to ensure safety and prevent damage.
Neodymium Magnet Manufacturing Methods:
Neodymium Magnets are typically manufactured by a powdered metallurgical process utilizing rigid steel or rubber molds.
