The manufacturing process of sintered NdFeB magnets involves the powder metallurgy technique. The raw materials are mixed together in a powdered form and then compacted into a desired shape using a pressing process. The compacted shape is then sintered at high temperatures to bond the particles together and form a solid magnet.
Sintered NdFeB magnets have a wide range of applications due to their strong magnetic properties. They are used in various industries, including automotive, electronics, renewable energy, and medical equipment. Some common applications include electric motors, generators, magnetic separators, magnetic resonance imaging (MRI) machines, and computer hard drives.
Despite their excellent magnetic properties, sintered NdFeB magnets also have some limitations. They are prone to corrosion and can be brittle, making them susceptible to breakage if mishandled. Therefore, protective coatings or platings are often applied to enhance their corrosion resistance and durability.
In summary, sintered NdFeB magnets are powerful permanent magnets with exceptional magnetic properties. They are widely used in many industries for various applications, but precautions must be taken to protect them from corrosion and breakage.
