Customized Ni-Cu-Ni Coating Magnet Rod Neodymium Bar NdFeB Magnetic
Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal composed of neodymium, iron, and boron (Nd2Fe14B).This type of magnet is a permanent magnet with magnetic properties second only to absolute zero degree holmium magnets, and is also the most commonly used rare earth magnet. Neodymium iron boron magnets are widely used in electronic products, such as hard drives, mobile phones, headphones, and battery powered tools.
Neodymium magnets are classified according to the material they are made of. As a very common rule, the higher the level (the number after "N"), the stronger the magnet. The highest grade neodymium magnet currently available is N52 The grade of commonly used neodymium magnets is N35, which is the most cost-effective brand. Any letter after the level refers to the temperature level of the magnet. If there is no letter after the grade, the magnet is standard temperature neodymium. The temperature rating is standard (not specified) - M – H – SH – UH – EH.
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℉) |
