About Neodymium Magnets:

After being introduced in the mid 1980’s, Neodymium magnets gained market share due to their high magnetic strength and resistance to demagnetization. Neo magnets do not have the high temperature resistance of other magnet materials, however they can be used in applications with maximum operating temperatures of 220 C. Because of a high iron content, they will corrode over time if not plated or coated. As with all magnet materials, NdFeB should never be used as a structural element in an application.
