Neodymium-Bonded Magnets are a type of permanent magnets made of neodymium iron boron (NdFeB) with a polymer or resin binder. Bonded-Neodymium Magnets are made by mixing neodymium iron boron particles with a polymer binder and forming it into a desired shape. This type of permanent magnet offers a combination of high magnetic strength, small size, and cost-effectiveness. Bonded-Neodymium Magnets are widely used in various applications, including motors, sensors, and medical equipment. They are available in a variety of shapes, such as disc, block, cylinder, ring, etc., and sizes that can be customized to meet specific requirements. Furthermore, these magnets can be magnetized in axial, radial, or multi-poles directions. Common grades of Neodymium-Bonded Magnets include BN-4, BN-6, BN-8, BN-10, and BN-12L, with a minimum order quantity of 100 pieces.
