Sintered Neodymium Magnets are made of Neodymium-Iron-Boron (NdFeB) material, which makes them one of the strongest magnets available. They are produced in a sintered process, which involves compressing and heating the material in a mold. This process ensures the magnets have a uniform structure and stable magnetic performance. It also allows for customization of the size and shape of the magnet according to the customer's needs. The magnets are coated with a layer of nickel to protect them from corrosion and provide a smooth finish. The high pull force of sintered neodymium magnets makes them ideal for a variety of applications, ranging from industrial manufacturing to consumer electronics. They also have the unique ability to have magnetic orientation in multiple directions, allowing for more precise control of magnetic fields. Sintered Neodymium Magnets are the perfect choice for anyone looking for a reliable and powerful magnet.
