Have you ever encountered the term "strong magnet" when searching for a specific type of magnet? So, what exactly is a strong magnet? Generally speaking, it refers to neodymium magnets or neodymium iron boron magnets. Compared to ferrite magnets, aluminum nickel cobalt magnets, and samarium cobalt magnets, neodymium iron boron magnets have superior magnetic properties. For example, neodymium iron boron magnets can attract objects up to 640 times their own weight, which is why they are called "strong magnets".
Neodymium iron boron magnets not only have the characteristics of small size, lightweight, and strong magnetism, but also are currently the most cost-effective magnets. It is expected that there will be no substitutes for neodymium iron boron magnetic materials in the next 20-30 years. The main raw materials for producing neodymium iron boron magnets include rare earth metals such as neodymium, praseodymium, pure iron, aluminum, and boron iron alloys.
Manufacturing technology is the core technology of the neodymium iron boron industry, mainly reflected in product uniformity, consistency, processing quality, coating quality, and other aspects.
As a third-generation rare earth permanent magnet material, neodymium iron boron magnets have extremely high cost-effectiveness and are widely used in fields such as electroacoustics, electronic appliances, motors, mechanical equipment, and healthcare. For example, in the field of electroacoustics, powerful magnets are widely used in speakers, receivers, microphones, alarms, stage sound systems, car sound systems, etc; In the field of electronics and electrical appliances, strong magnets are also widely used in permanent magnet vacuum circuit breakers, magnetic holding relays, energy meters, water meters, sound meters, reed tubes, sensors, and other fields. In addition, various fields such as motors, magnetic separators, magnetic cranes, nuclear magnetic resonance instruments, medical equipment, magnetic therapy health products, processes, gifts, etc. also require strong magnets.
