2:17 samarium cobalt magnet, also known as Sm2Co17, is a magnetic material made of metal samarium, cobalt, copper, iron, and zirconium in a certain proportion, after smelting, crushing, pressing, sintering, and aging. The maximum magnetic energy product range is between 20-35MGOe, and the maximum working temperature is 350 ℃. As 2:17 has a low temperature coefficient and good corrosion resistance, its magnetic performance exceeds that of NdFeB magnets at high temperatures, it is widely used in aerospace, military fields, high-temperature motors, automotive sensors, and various magnetic drives, magnetic pump and microwave devices and other fields.
2:17 samarium cobalt is extremely brittle and difficult to process into complex shapes or particularly thin flakes and thin-walled rings. In addition, it is easy to cause small missing corners during product processing or process turnover, inspection, and magnetization. We believe that as long as it does not affect the magnetic performance or function, it should be regarded as a qualified product. Special reminder，users must be careful during the assembly process to avoid the attraction of two magnets or iron materials, causing the magnet to be broken or personal injury.
Sm2Co17 magnet is not easy to be saturated and magnetized. If users need to magnetize by themselves, he must know how big the magnetic field of the magnetizing equipment is, and then choose the appropriate grade.
