NdFeB magnets are tetragonal crystals formed from neodymium, iron, and boron (Nd₂Fe₁₄B), also known as NdFeB magnets. The magnetic energy product (BHmax) of this magnet is greater than the samarium cobalt magnet, which is the largest magnetic energy product in the world at that time. It has the characteristics of high magnetic energy product, high coercivity and high remanence, and is widely used in electronic products, such as hard disks, mobile phones, headphones and battery-powered tools.
NdFeB magnet has excellent magnetic properties, and its magnetic energy product is greater than samarium cobalt magnet, which is the largest magnetic energy product in the world at that time. In addition, it also has the characteristics of high coercivity and high remanence, which enables it to maintain stable magnetic properties. Therefore, it is widely used in electronic products, electrical appliances, packaging, motors, toys, leather goods, automotive machinery and other fields.
In order to protect permanent magnet materials from corrosion and mechanical damage, surface treatment is required, such as gold plating, nickel plating, galvanizing and electrophoresis. At the same time, it is necessary to pay attention to avoid colliding with other metals or hard objects during use, so as not to damage its magnetic properties.
