Neodymium Iron Boron Shape
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 MEOe. These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.
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:
Neo 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 without conflicting with a Neodymium Magnet’s orientation.
