Neodymium Magnets The Material

Neodymium magnets overall, are the world's strongest permanent magnets. Although, not all neodymium ring magnets share the same characteristics. The Grade of a neodymium ring magnet will provide an idea of the strength of a neodymium ring magnet. The most common commercially available grades generally run N35- N52.  N35 is the weakest (but by no means weak) and N52 is currently the strongest. There are some special use grades as well. A larger piece of neodymium of a weaker grade may be ultimately stronger than a smaller but higher grade piece. Our strong ring magnets are designed & manufactured to meet stringent quality standards of both external and our own standards.
