High working temperature rod Neodymium magnets
Horizon supply Neodymium magnets in round shaped. Usually we call them cylinder Neodymium magnets, disc Neodymium magnets or rod Neodymium magnets.
Neodymium magnets known as NdFeB, Neodymium-Iron-Boron, Neo, NIB or Rare Earth Neodymium magnets, are the third generation of rare earth permanent magnets. They offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades. These qualities have made NdFeB magnets preferable over the commonly used larger and less powerful Ferrite magnets.
Although the Curie temperature for NdFeB materials is 310-370ºC, some irreversible loss of output may be expected at even moderate temperatures. NdFeB magnets also have a moderately high reversible temperature coefficient of Br which reduces total magnetic output as temperature rises. Selection of NdFeB instead of SmCo, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.
However, they are sensitive to oxidization and can develop corrosion, so they require surface protection like phosphate, passivation, Ni, NiCuNi, Zn, Epoxy, NiCuNi+Sn or others.
