Strong magnet thickness

Why can't strong neodymium magnets be made too thin?

This is because neodymium magnet is a sintered material, which is hard and brittle like ceramic. Once the thickness becomes too thin (such as 0.3mm, 0.2mm, or even thinner), it is highly prone to chipping and cracking during processes like slicing, grinding, electroplating, and packaging, resulting in a significant drop in yield rate....
