The M series of NdeFeB magnets from Sanhuan (Ningbo) NdFeB Magnetics Co. Ltd exhibits high resistance against erosion and oxidation, wide operating temperature range, and is suitable for use in automotive, audio, magnetic inspection system, and magnetic transmission machine applications.

They come in ring, cylinder, square, or tile shapes and have surfaces treated with zinc, nickel, gold, or epoxy resin plating. Maximum energy product is between 28MGOe to 30MGOe (N30M), 31MGOe to 33MGOe (N33M), 33MGOe to 35MGOe (N35M), 36MGOe to 38MGOe (N38M), 38MGOe to 40MGOe (N40M), 40MGOe to 42MGOe (N42M), or 43MGOe to 45MGOe (N45M).

They have a residual induction between 11.2kGs to 13.7KGs and a coercive force between 9.8kOe and 11.4kOe. Intrinsic coercivity is at least 14KOe.
