Rare earth permanent magnet material (NdFeB Nd2Fe14B): Divided into the following three types according to the production process. Bonded NdFeB ——Bonded NdFeB is a composite NdFeB permanent magnet made by uniformly mixing NdFeB powder with binders such as resin, plastic or low-melting point metal, and then compressing, extruding or injection molding. The product is formed once, without secondary processing, and can be directly made into various complex shapes. Bonded NdFeB is magnetic in all directions and can be processed into NdFeB compression molds and injection molds. High precision, excellent magnetic properties, good corrosion resistance, good temperature stability. Sintered NdFeB Sintered NdFeB permanent magnets are smelted after jet milling, with high coercive force and extremely high magnetic properties. The maximum magnetic energy product (BHmax) is 10 times higher than that of ferrite (Ferrite) above. Its own mechanical properties are also quite good, and it can cut and process different shapes and drill holes. High-performance products have a maximum operating temperature of up to 200°C. Due to its substance content, it is easy to cause corrosion, so the surface must be treated with different coatings according to different requirements. (such as galvanized, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel, etc.). Very hard and brittle, with high resistance to demagnetization, high cost/performance ratio, not suitable for high operating temperatures (>200°C). Injection NdFeB Extremely high precision, easy to make thin-walled rings or thin magnets with complex anisotropic shapes. Permanent magnets are widely used in various fields such as electronics, electricity, machinery, transportation, medical treatment and daily necessities.

GET A QUOTEThis neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos. Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.
