Common stock sizes range from 0.250" to blocks that measure up to 10" on one dimension. Larger sizes can be made by assembling several smaller magnets together. Standard ceramic shapes include rectangles, discs, rings, and arc segments. Non-standard shapes can be custom fabricated to specifications from raw stock; we can custom manufacture virtually
Ceramic(ferrite) magnets are produced by pressing and sintering fine powder into the required shape. Because they are hard and brittle, they require specialized machining techniques and are best machined in an un-magnetized state. We are fully equipped to machine these materials to your custom specifications.
Ceramic(ferrite) magnets can be used at temperatures up to about 525⁰F (300⁰C). Magnetic properties decline fairly linearly with temperature for this material.
Ceramic(ferrite) magnets require magnetizing fields of about 10 kilo Oersteds. They can be magnetized with multiple poles on one or both pole surfaces. No special handling precautions are required, except that large blocks of Ceramic magnets are powerful, so special care should be taken to ensure that they do not snap towards each other.
