Ferrite is a kind of a ferromagnetic metal oxide. The electrical properties, the resistivity of the ferrite is higher than metal, alloy magnetic materials, and they have a high dielectric properties. Ferrite Magnet also reflected in the high frequency with high magnetic permeability. Thus, high-frequency ferrite weak areas have become widely used non-metallic magnetic materials. They are widely applied in speakers, cars, water pumps, disk drivers, starting motors, and electronic products. 1.2 Overview of our Ferrite Magnet 1.3 Close shot of our ferrite magnet samples 1.4 The Grade of ferrite magnet we can supply
1.5 Magnetised direction 1.6 Physical performance of Ferrite Magnet
1.7 Manufacture Process 1.Dry process: By dry process, can produce isotropic & anisotropic magnets;the tool can be changed and developed easily.
2.Wet process: By wet process, only anisotropic magnets can be produced;it is complicated to change the tool and the tooling charge is much higher 1.8 Detailed Four Step Quality Control STEP 1: After the mould comes out. Test the size, tolerance and the property (BH(max), Br, Hcj, Hcb) of the mould, only the qualified products turn to next step. STEP 2: After grinding, inspect the size and tolerance of the magnet with precision, only the qualified products turn to next step. STEP 3: After cutting the thickness, examine the tolerance of thickness, guass and pull force, only the qualified products turn to next step. STEP 4: Recheck the size and tolerance, surface of the magnet, exclude the unqualified (damaged, bad coating) pieces, then come to magnetizing and packaging. 2 More correspond Information of Ferrite Magnet 2.1 Package 2.2 Over 200 sizes moulds and Over 400 sizes stock Please check a small part of our stock types of Neodymium Magnet in website attached document !
