Available Grades of Neo
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.
Neodymium disc 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.
Neodymium magnets are very susceptible to elevated operating temperatures and the application requirements should be considered before selecting a particular grade of Neo.
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.
Common uses in different fields:
Magnetic resonance imaging
Health bandages and plasters
Specialty door catches
Filters & strainers
High performance motors
Micromotor / servo motor
