Strong Permanent Magnetic Materials Rare Earth Ndfeb Magnets Ring Magnet
Neodymium ring magnets are strong rare earth magnets that are circular in shape and have a hollow center. Neodymium (also known as "Neo", "NdFeb", or "NIB") ring magnets are the most powerful magnets on the market today, with far more magnetic properties than other permanent magnet materials. Due to its high magnetic strength, neodymium ring magnets have replaced other magnetic materials to make the design smaller and achieve the same effect.
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℉) |
Sintered Neodymium Iron Boron Magnets or "NdFeB" magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades. NdFeB magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
