Thin Neodymium Magnets

The flat neodymium magnets with thickness under 2mm are classified as thin neodymium magnets. Thin neodymium magnets are characterized by length and width, or diameter much larger than thickness. That thickness has a relation with the length, width, and diameter of a magnet. The thinnest thin small and round neodymium magnets we produced were only 0.5mm.


Available surface coating for thin powerful&strong magnets


Thin neodymium magnets have strong and powerful magnetic force, but the thin thin powerful&strong magnets are not rust-proof, proper surface protection treatment must be adapted according to various applications. Please choose the best coating from the available coating table as below.

Caution is necessary for handling thin neodymium strong magnets


Neodymium-iron-boron material itself is very brittle, thin neodymium rare earth magnets are easy to be damaged due to the impact between each other in the process of operation. So please make sure to read the safety neodymium magnets' information before using and handling thin neodymium strong magnets.


The grade for thin neodymium strong magnets


The highest available grade for thin neodymium strong magnets is N52, the table list out all available grade for thin neodymium magnets, and there is the maximum working temperature for each grade, please correctly choose the thin neodymium magnet grade.
