Although many customers often need to buy strong rare earth NdFeB magnets, they know little about them. The editor often encounters such customers. One customer said: "I need strong magnetism, high temperature magnets", but asked what performance it is. He doesn't know how big the magnetism is. Today, let's briefly introduce the performance of rare earth NdFeB strong magnets.
Rare earth NdFeB strong magnets refer to strong magnets, professional names: rare earth strong magnets, NdFeB, etc. This kind of magnet generally has high performance and strong magnetic force, and is widely used in toys, packaging boxes, lamps, handicrafts, speakers, machinery , health care products, electronic products, hardware tools and other products.
Generally used are N33, N35, N38 and other three common properties of rare earth NdFeB strong magnets, that is, ordinary materials. Generally, the higher the performance, the better the materials, and the higher the price. So, generally speaking, if the requirements are not very high, the use of magnets with these three properties is almost the same.
N40 and above are high-performance rare earth neodymium iron boron strong magnets. This performance is generally used in mobile phones, precision instruments, aerospace, and cutting-edge scientific research. It can be divided into nine properties: N40, N42, N45, N48, N50, and N52. The nine properties are all within ≤80℃. Once this temperature is exceeded, they will demagnetize.
So if customers consider high temperature resistance and want high performance, it is recommended to use the following properties:
①It ends with M, for example: N50M, the temperature resistance is generally ≤100℃;
② ends with H, for example: N48H, the temperature resistance is generally ≤120℃;
③ ends with SH, for example: N45SH, the temperature resistance is generally ≤150℃;
④ ends with UH, for example: N35UH, the temperature resistance is generally ≤180℃;
⑤ ends with EH, for example: N35EH, the temperature resistance is generally ≤200℃;
