Description
Neodymium Magnet
Neodymium magnet still offers the strongest magnetic power nowadays and has been widely served to vast kinds of application, include high-performance permanent motors, brushless DC motors, magnetic separators, magnetic resonance imaging (MRI), sensors, loudspeakers, consumer electronics, green energy and so on.
Introduction of Manufacturing Process
Sintered Neodymium Countersunk 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.
