Phosphate treatment can provide protection for Neodymium magnets. To Protect the base metal and prevent the base metal from corroding to some extent.

N42SH 25.4 X 6.35 X 6.35mm Neodymium Block Magnets with Phosphate Treatment

The Information of Phosphate Treatment Applied for the Neodymium Magnets
Phosphate coating can provide protection to the base metal and prevent the base metal from corroding to some extent and has the characteristics of no coating thickness. Phosphate treatment before painting can improve adhesion strength and corrosion resistance of the paint layer.
