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 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 have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Neodymium is alloyed with Terbium and Dysprosium in order to preserve its magnetic properties at high temperatures.
1. NdFeB rare earth magnets are mainly used in motors, generators, poly fitters, maesuring instruments, magnetic drives, magnetic resonnce, sensors, linearactuators, microphone assemblies, apeakers, magnetic hooks, MRI/NMR.
