Monthly price trend of neodymium magnet raw materials June 2023

Generally, the practitioners of NdFeB magnet manufacturers have the most contact with sintered NdFeB magnets, that is, sintered magnets. According to different production processes, there are injection-molded NdFeB magnets in the classification of NdFeB products, What are the differences between injection molded NdFeB magnets and sintered NdFeB magnets?

Weekly price trend of neodymium magnet raw material May 29-June 2

Ferrite magnets has high coercive force Hcb, low recovery magnetic permeability mr, low density (4.5~5.2g/cm3), resistance to oxidation and corrosion, the working part of the demagnetization curve is a straight line, good dynamic characteristics, no need for magnetic stabilization treatment, The material utilization rate is high and the price is cheap. The disadvantage is that the residual magnetism Br is low, the temperature coefficient of magnetic induction is large, the sintered ferrite is hard and fragile, it is difficult to machine, and the resistivity is very large (1012~1014mW.cm), which cannot be cut by wire cutting or EDM. Grinding should be done with a toothless saw or diamond grinder.
