N52 Strong Magnetic Materials Rectangular Neodymium Magnets Block NdFeB Rare Earth Magnet
NdFeB Magnet
NdFeB permanent magnets are developing rapidly and widely used due to their excellent performance, abundant raw materials and reasonable prices. Most block magnets have their north and south pole on the two largest areas. The few exceptions, which are magnetized in longitudinal direction, are specifically marked.These block magnets, like our other super magnets, are made of a special NdFeB alloy, which allows neodymium block magnets to achieve extreme adhesive force of up to 200 kg. It is mainly used in micro and special motors, permanent magnet instruments, electronics industry, automobile industry, petrochemical industry, nuclear magnetic resonance equipment, audio equipment, magnetic levitation system, magnetic transmission mechanism and magnetic therapy equipment. The surface usually needs to be electroplated, such as galvanized, nickel, silver, gold, etc., can also be phosphated or sprayed with epoxy resin to extend the service life and make it more beautiful.
