Sintered NdFeB are formed by powder metallurgical processes. The magnetic performance of all grades is optimized by applying a magnetic field during the pressing operation, thus producing a preferred direction of magnetization (anisotropy). Our sintered NdFeB magnets have 2distinct characteristics: High corrosion resistance and Low temperature coefficient. The newly developed L-T Sintered NdFeB Series has outstanding corrosion resistance and high working temperature compared to the normal grades.

Key Benefits

The strongest magnets in the world. They can lift up to 1000 times their own weight.
Far better permanent magnetic performance compared with traditional magnets, but the price is relatively low. (by weight about 20times Ferrite magnet, by dollars per BHmax about 1.5 times Ferrite magnet)
Wide range of grades with new ones regularly being developed. Available from very small sizes to large blocks.
Relatively easy to machine, compare to AlNiCo and SmCo magnets
High resistance to demagnetization.

Key Challenge

Brittle and hard.
Properties deteriorate rapidly at temperatures in excess of about 150C (depending on grade and permeance coefficient magnet is operating at) The highest working temperature can be 230C (AH grade L-T Series).

Need to be protected against oxidation_by coating or plating the magnets.

Quick Facts

Density: 7.5-7.6g/cm3
Saturation magnetizing field required: About 25KOe
Shape Available: Blocks, bars, discs, rings, arc segments, etc.
Grade Available: N35 to N52, N, M, H, SH, UH, EH, AH series
Size: The largest can be 120mmx100mmx50mm, the smallest can be 2.00mmx1.50mmx1mm for the block shape.
Machine: Neodymium magnets should be machined by grinding using diamond wheels. However, of the hard magnets materials, neo magnets are the least difficult to machine.


Applications

Voice coil motors in hard disc motor, pick-up in optical disk drives, mobile phones, magnetic resonance imagers, Hi-Fi systems, auto motors, wind-power generators, magnetic separators, lifting equipment, space flight equipment and new energy products. Especially suitable for the development of high-performance, compact and lightweight products.
