Ferrite / Ceramic
Ferrite magnets have the characteristic of high cost-performance, wide application and good corrosion resistance that does not require surface treatment. Our company can produce a variety of high-performance magnets in different shapes, such as bows, rings, discs, blocks and other special shapes. The main raw material of ferrite magnets is SrO and Fe203.

Note:
1. From CJMG36 to CJMG37B there are lanthane cobalt magnets.
2. The data in the table are the central value, where the tolerance of Br ± 10mT, the tolerance of Hcb ± 8kA/m, the tolerance Hcj ± 8kA/m, the maximum tolerance (BH) ± 0.8kj/m³.
3. The magnetic particle size is divided into A, B, C three, A for the size of the ball material ≤ 10 mm, B for the coarse powder particle size of 3-5 μm, C for the fine particle size < 1μm.
