Product Review

Ceramic magnets or ferrite magnets are sintered permanent magnets composed of barium or strontium carbonate, and iron oxide. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost. The sorts of hard ferrite magnets are manifold and complete. They are charcoal gray in color and usually appear in the forms of toroid, circular disk, square, bar, arc segment, blocks, rings, cylinders special magnets etc. The detail specifications are up to hundreds of kinds.
The corrosion resistance of Ferrite is considered excellent and no surface treatments are required. It can be used in temperatures up to 80 degrees C. However, Ceramic magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications, some form of coating may be required. Standard parts include blocks, discs, rings & round bars in different dimensional specifications. Magnets are available in different shapes & sizes and can also be custom fabricated according to specifications & tolerances.

Ferrite magnets are very hard and brittle, and require specialized machining techniques. Moreover, they should be machined in an unmagnetized state. We are equipped to machine these materials to specifications. Anisotropic grades are oriented in the manufacturing direction, and must be magnetized in the direction of orientation. Isotropic grades are not oriented and can be magnetized in any direction, although some degree of greater magnetic strength will be found in the pressing dimension, usually the shortest dimension.
