Ceramic

Ceramic magnet material is a nonmetallic compound of iron oxide, strontium ferrite and small quantities of other metal oxides. The compound is calcined wet ball milled to a fine particle size, binders are added, then the mix is compacted in a press. The compacted shapes are fired at high temperatures in kilns to a closely controlled temperature cycle. Upon cooling, the parts are diamond sawed and diamond wheel ground to specifications.

Low cost, light weight and fairly high energy, Ceramic is a hard, brittle, nonconductive material. It is difficult to grind and cannot be E.M.D.’d, machined or drilled by normal methods. Ceramic is dense black or blue-black in color. It has a thin cross section, is mostly available in slabs or rings and is usually oriented magnetically through its thickness. Ceramic magnet material performs best when temperatures do not exceed 350°F.

Raw magnet material is available in many different types, shapes, sizes and strengths. When selecting magnetic material to perform a given task, certain specifications need to be considered: dimensions, direction of the materials, magnetic orientation, tolerances, finish, strength, and the type of raw magnetic material desired, such as Rare Earth magnets, Ceramic magnets or even Flexible magnetic rubber. Mag-Mate raw magnet material meets Magnetic Materials Producers Association (MMPA) standards for physical quality and magnetic properties.
