Ferrite

Magnets made by sintering pulverised ferrite, strontium and iron, with the following specifications:

- Working temperatures up to 450 °C
- Maximum energy product (BH max): up to 4.4 MGOe
- Residual induction (Br): up to 4.5 kGs

Magnets made of sintered ferrite can be created using a "wet" or "dry" manufacturing process: this allows for different types of shapes: segments, cylinders, rings, blocks and many others thanks to the use of moulds. Because no further coatings are required, the problem of corrosion is reduced to a minimum. There are various types of magnetisation available: radial, axial and diametrical.
