Perfect for workshops, garages, manufacturing facilities, and inside your truck or van. When mounted, these holders are held firmly in place by welded tabs, with 1/4” holes for mounting screws (included).
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 "e;oriented"e; (anisotropic). If not exposed to a magnetic field at time of formation, it is called "e;non-oriented"e; (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 "e;ceramic"e; magnet.
Lastly, the magnet is finish-ground to size with a diamond-bladed grinding wheel, magnetized, and inspected for shipment.
Tolerances -Pressed dimensions are either +/– 2% or +/– .025 in., whichever is greater. Cut dimensions are either +/– 3% or +/– .025 in., whichever is greater. Thickness tolerances are normally ground to +/– .005 in., according to International Magnetics Association (IMA).
Visual imperfections such as cracks, porosity, voids, surface finish, etc. (commonly found in sintered ceramic magnets) do not constitute 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% 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 "e;jump at"e; an attracting object.
