AZ Industries carries a wide range of shapes and sizes of ceramic magnets. Our ceramic (ferrite) magnets have rectangular blocks from small to large, cylinders, rings, discs, triangles, and special shapes. As one of the top magnet suppliers and custom magnet manufacturers in America, we offer some of the shortest lead times for custom machined magnets.
We have many standard sizes available off the shelf and special sizes can be made upon request. Ceramic, or ferrite, magnets are made by the pressing and sintering of a powdered mixture of strontium and iron oxide. They are the most widely used magnets today. Ceramic is inexpensive and corrosion resistant, but cannot withstand impact or flexing as they will chip and crack due to their hard and brittle nature.
No surface treatments are necessary for ferrite magnets. However, a thin film of fine magnet powder on the surface is common and a coating may be used for cleanliness purposes. Common grades of ceramic are 1, 5 and 8 and can be found in the form of discs, rings, blocks, cylinders, and sometimes arcs.
