Description
Neodymium Magnet
Neodymium NdFeB magnets can be divided into two types: bonded NdFeB and sintered NdFeB. Bonding is actually injection molding, while sintering is vacuum molding through high-temperature heating.
Features: high magnetic energy product and coercive force, high energy density, high cost performance.
Shape:Cylinder/Disc/Round/Block/Arc/Ring/Hook/Sphere/Pot/Countersunk/Segment/Horseshoe or personalized request.
Coating: zinc, nickel, epoxy resin, nickel-copper-nickel, gold, etc.
Introduction of Manufacturing Process
Sintered Neodymium Cylinder 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.
