Smooth stainless steel trays have powerful ceramic magnets with rubber covers in the base to secure them to a metal toolbox or table. Makes a great gift.
A rubber-covered magnet keeps the parts tray firmly attached to a metal workbench, car fender or any other ferrous metal surface without scratching.
Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide.
Manufacturing - A powdered mixture of strontium carbonate and iron oxide is injected into a wet or dry press for forming. During this process, a magnetic field is applied in the direction of preferred magnetization to orient the material and increase the magnet's performance potential. This magnet is considered "oriented" (anisotropic). If not exposed to a magnetic field at the time of formation, it is called "non- oriented" (isotropic).
After the molding process, the magnetic material is then sintered at about 2,000°F. The sintering process is similar to that of kilning ceramic pottery, thus the popular name "ceramic" magnet.
Lastly, the magnet is finished-ground to size with a diamond-bladed grinding wheel, magnetized, and inspected for shipment.
Visual imperfections such as cracks, porosity, voids, surface finish, etc. (commonly found in sintered ceramic magnets) do not constitute a cause for rejection. Chips are acceptable if no more than 5% of the pole surface is removed. Cracks are acceptable, provided they do not extend across more than 50 percent of the pole surface.
Magnetizing and Handling - Ceramic magnet material is extremely brittle and can chip or break if dropped on a hard surface, or if allowed to "jump at" an attracting object.
