SDM Neodymium Magnet
Neodymium Magnet is a type of rare-earth permanent magnet, boasts the strongest magnetic properties among all
commercially available magnets. Its high energy product, combined with excellent mechanical properties, makes it an ideal choice for applications requiring high magnetic field strength in compact designs, such as electric motors, generators, sensors,
speakers, and magnetic resonance imaging (MRI) machines. The material's versatility and durability have revolutionized numerous
industries, enhancing efficiency and performance in numerous devices worldwide.
Introduction of Manufacturing Process
Sintered Neodymium magnet is prepared by the raw materials being melted under vacuum or inert gas atmosphere in an induction melting furnace and processed in the strip caster and thus cooled to form alloy strip. The strips are crushed and pulverized to form a fine powder ranging from 3 to 7 microns in particle size. The powder is subsequently compacted in an aligning field and sintered into dense bodies. The blanks are then machined to the specific shapes, surface treated and magnetized.
