Product Description

product name: Sintered Neodymium Block magnet





Detailed Product Description

Relatively low cost ;
poor resistance to corrosion and should have a coating ;
Very high strength;
can replace SmCo magnets

Sintered neodymium-iron-boron (Nd-Fe-B) magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 35 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices.
  • Neodymium magnets are the most powerful commercially produced magnets.
  • NdFeB magnets have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
  • NdFeB magnets can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
  • Very high strength.
  • Relatively low cost.
  • Compared to Alnico and SmCo magnets, relatively easy to machine.
Quick Leads
  • Manufacturing process - sintering (most common), injection molding, and compression bonding.
  • Shapes available - blocks, bars, discs, rings, cylinders, arc segments, or irregular shapes, etc.
  • Wide range of Grades available- from about 3330 to 5311. (First 2 digits represent BH.max, and second two digits represent Intrinsic Coercivity, Hci.)
  • Density: 7.4 -7.6 g/ cm3; Hardness: 600 {Hv}
  • Some particular grades can achieve 200°c the max working temperature.
  • Saturation magnetizing field required - about 35kOe
  • Machining - Neodymium magnets should be machined by grinding using diamond wheels, however, of the hard magnet materials, Neo magnets are the least difficult to machine. We can successfully machine very small magnets.
