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 4 distinct characteristics: High corrosion resistance and Low temperature coefficient, Large dimensions or Small sizes. 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. (byweight 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.
