Thin Neodymium Magnets

Name: Thin Neodymium Magnets
Brand: Ningbo Beilun Meank Magnetics Co.,Ltd.

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.

Surface	Coating	Thickness (Microns)	Color	Resistance
Passivation		1	Silver Grey	Temporary Protection
Nickel	Ni+Ni	10-20	Bright Silver	Excellent Against Humidity
Nickel	Ni+Cu+Ni	10-20	Bright Silver	Good Against Salt Spray
Zinc	Zn	8-20	Bright Blue	Excellent Against Salt Spray
Zinc	C-Zn	8-20	Shinny Color	Superior Against Humidity

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.
