Neodymium Rare Earth Block Magnets , Powerful Permanent Magnets N52
High Quality NdFeB Magnet N52 Sintered Neodymium Block Permanent Magnet
The third generation of rare earth permanent magnet NdFeB is the most powerful permanent magnet in modern magnets. It not only has the characteristics of high remanence, high coercivity, high magnetic energy product, high performance-to-price ratio, but also is easy to be processed into various sizes.
There are many levels of NdFeB magnets
| Grade | Max Operating Temperature | Grade | Max Operating Temperature |
| N35-N48 | 80℃ (176℉) | 30SH-45SH | 150℃ (302℉) |
| N50-N52 | 60℃ (140℉) | 30UH-45UH | 180℃ (356℉) |
| 30M-50M | 100℃ (212℉) | 28EH-38EH | 200℃ (392℉) |
| 30H-48H | 120℃ (248℉) | 28AH-35AH | 230℃ (446℉) |
