Explanation
It is a plastic bonded permanent magnet material by mixing the powder with permanent magnetic properties with organic materials and molding or injection molding. The magnetic properties of composite permanent-magnetic material are lower than that of sintered body due to the filling of non-magnetic material with volume fraction of 10% -15%. There are two main types of composite permanent-magnetic material: composition barium and electric ferrite; composition the rare earth permanent magnetic material.
