What is the main difference between injection molded ferrite and NdFeB
The injection molded ferrite has much higher resistivity than metal and alloy magnetic materials, and also has higher dielectric properties, showing higher permeability at high frequencies.
1, In the price, injection molding ferrite is much lower than injection molding NdFeB.
2, injection molding ferrite magnet has very good temperature resistance, and the ordinary Ndfeb usually only can take 80 degrees, above this working temperature NdFeB will be demagnetized.
3, Injection molding ferrite has good stability, it is already an oxide material, so it's very stable. but NdFeB is an alloy material, so the NdFeB is easy to be oxidated, it should have a coating to prevent the oxidation.
