FAQ - Frequently Asked Questions

Why does the coating of my magnets chip?

To protect our neodymium magnets from corrosion, they have a thin coating of nickel copper nickel. This coating can crack or chip due to collision or strong pressure. Heavy blows can even break magnets. This is not a quality defect, but rather a typical product feature: The material neodymium iron boron is very magnetic but also brittle, because it is sintered from metal powders. Therefore, careful handling of magnets is recommended.
