Magnet Sintered Zn Coating NdFeB Ring Magnet For Industrial
Neodymium magnet is a general term for strong magnets, with a
chemical formula of Nd2Fe14B. It is an artificial permanent magnet
with the strongest magnetic force to date, with a material grade of
N35-N52. It can be processed into magnets of different shapes
according to different requirements, such as tiles, blocks, punched
holes, magnets, magnetic rods, protrusions, ladders, etc.
There are many levels of NdFeB magnets
| grade | Max Operating Temperature | grade | Max Operating Temperature |
| N30-N54 | 80℃(176℉) | N30UH-N45UH | 180℃(356℉) |
| N30M-N52M | 100℃(212℉) | N30EH-N38EH | 200℃(392℉) |
| N30H-N52H | 120℃(248℉) | N32AH | 220℃(428℉) |
| N30SH-N45SH | 150℃(302℉) | |
