Sintering NdFeB hole
• 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 1500C (depending on grade and permeance coefficient magnet is operating at) The highest working temperature can be 2300C (AH grade L-T Series).
• Need to be protected against oxidation—by coating or plating the magnets.
Quick Facts
Density: 7.6g/cm3
Saturation magnetizing field required: about 25KOe
Shape Available: blocks, bars, discs, rings, arc segments, etc.
Grade Available:N35 to N53,N,M,H,SH,UH,EH, AH series
Size: the largest can be 150mmx150mmx50mm, the smallest can be 2.00mmx1.50mmx0.50mm 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.
