The "Neo" magnets are a first decision for some applications as they offer the best execution with the littlest volume. Neodymium magnets exist in an assortment of evaluations. These evaluations shift in attractive yield execution as well as change with temperature rating. The greatest prescribed temperature of operation for the "Neo" magnets is +200 to +230 degrees C in spite of the fact that as far as possible is really subject to the magnet shape and the aggregate attractive circuit (so as far as possible are truly just rough rule values). This is talked about in the segment called Temperature Ratings. 
 

All the Neodymium Iron Boron, NdFeB, magnets are inclined to consumption (a technique like rusting). All Neodymium Iron Boron, NdFeB, magnets will require a type of defensive covering. The standard covering is a triple layer plating of Nickel-Copper-Nickel (Ni-Cu-Ni). Unless asked for something else, this Ni-Cu-Ni covering is constantly connected to the magnets. It ought to be noticed that the level of assurance given by any covering relies on upon the environment the magnet will be subjected to and how the covering is taken care of.
