Permanent neodymium magnets also knowas rare earth neodymium magnets, are made from rare material alloy of neodymium, iron, ferrite etc. because ofit’s magnetic performance, they are widely used in different applications. This magnet is under grade N42SH, this SH material can be working constantly with temperature higher than 100°. N42SH grade with Br range from 12.9KGs to 13.3KGs, (BH)Max range from 318KJ/m3 to 342KJ/m3. Most our magnets are customized size, it depends on the end application of thismagnets. Our leading time for such magnets normally 22 to 25 days. It takeslonger time for the pre-production period. As higher grade magnets included Dycontent which the material formula is complicated. Please feel free to contactus for your better choice of motor magnets.
