Bonded Magnetic ferrite powder XIANGYING
Bonded magnetic ferrite powder have good compatibility with different kinds of synthetic materials, such as nylon, resin, polyvinyl chloride and rubber etc. Bonded magnetic ferrite powder can be used for making bonded ferrite magnets by calendering, extruding and injecting. We supplly barium magnetic ferrite powder and strontium magnetic ferrite powder.All the materials are in accordance with the European RoHS directive.

Magnetic Ferrite Powder
The magnetic ferrite powder are suitable for producing different grades of hard ferrite magnets by wet pressing or dry pressing. We supply the magnetic ferrite powders in three forms: granular powder (6-12mm), coarse powder (3-6um), fine powder (0.75-1.05um) according to the needs of clients. The magnetic ferrite powder can be classified as isotropic magnetic ferrite powder and anisotropic magnetic ferrite powder. Anisotropic magnetic ferrite powder has better orientability.
