The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe

how "strong" a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.

One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the "stronger" the magnet.

Unprotected NdFeB magnets are subject to corronsion. Surface treatments has ben developed that

allow them to be used in most applications. These treatments include copper, silver,, gold, nickel,

zinc and tin plating and epoxy resin coating.
Beneficial characteristics of NdFeB magnets include their very high energy product, very high

coercive force, and moderate temperature stability. Drawbacks include lower mechanical strength,

and low corrosion resistance when not properly coated or plated.

Magnetic Grades and Temperature:

The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe

how "strong" a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.

One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the "stronger" the magnet. 

Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material
comes in many different heat tolerances but as the heat tolerance increases the maximum available fulx density decreases:
