FERRITE MAGNET

FERRITE MAGNET

The main raw material of ferrite magnets is SrO and Fe203. Ferrite magnets have the feature of high cost-performance, wide application, good corrosion resistance which does not require surface treatment. Our company can produce a variety of high-performance magnets in different shapes such as arcs, rings, discs, blocks and other special shapes. With our specific formula, we can produce ultra-high-performance ferrite -- lanthanum cobalt magnet

Note:

1.From CJMG36--CJMG37B are Lanthanum cobalt magnet.

2.The data in the table is the center value, where Br tolerance ± 10mT,Hcb tolerance ± 8kA/m,Hcj tolerance ± 8kA/m,(BH)max tolerance ± 0.8kj / m³,

3.the magnetic particle size is divided into A, B, C three, A for the ball material size ≤ 10mm, B for the coarse powder particle size of 3-5μm, C for the fine particle size < 1μm.
