Neodymium Motor Magnet Customization Of Arc Shape NdFeB Magnets
Sintered neodymium iron boron is a new type of permanent magnet material, which is an alloy composed of rare earth metal nd fe-b. Among them, nd accounts for 5-15% of the total weight, fe accounts for 1-2%, and the content of b is around 1%.
Advantages: (1) High remanence; (2) Low coercivity; (3) High saturation magnetism; (4) Good temperature characteristics; (5) Excellent corrosion resistance; (6) Lower resistivity. (7) High mechanical strength and processing performance; (8) Good thermal stability. (9) It can be made into products with complex shapes, such as disc type bipolar motors, with a content of about 1%.
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℉) |
