These are the highest commercially available grades of Neodymium, offering maximum magnetic energy (BHmax).
For large-scale industrial needs, platforms like Alibaba connect buyers directly with manufacturers of N55-grade materials.

This is the weight a magnet can hold. For instance, N52 magnets provide a significantly higher pull force than N45 or N35 magnets of the same physical size, allowing for more compact designs. Material Grades: These are the highest commercially available grades of
