Info from Bunting Magnetics
- Economical Magnets Stocked For A Wide Range of Applications - excerpts below from bunting-magnetics.com
- "CERAMIC GRADES 5, 8, & 1 have become the most widely specified magnetic materials. Low cost, light weight, a relatively high energy product, and good resistance to demagnetization account for the widespread use of ceramic magnets."
- "CERAMIC 5 MAGNETS become highly oriented during the manufacturing process and must be magnetized in the direction of their orientation."
- "Ceramics are sintered from Barium or Strontium Ferrite."
- "They retain about 45 percent of their room-temperature magnetic specifications at 350 degrees Fahrenheit."
- "Degradation with increasing temperature is nearly linear, and changes in magnetization are essentially reversible up to approximately 840 degrees F, at which temperature Ceramic magnets become completely demagnetized."
- Demagnetization Curves for Ceramic 5 & 8 Magnets shown (see link above)
- "CERAMIC 5 MAGNETS become highly oriented during the manufacturing process and must be magnetized in the direction of their orientation."
- "CERAMIC 8 MAGNETS are made from a premium strontium base material that exhibits an excellent peak energy product and even greater resistance to demagnetization than its Ceramic 5 counterpart. Its higher coercive properties result in a more useful operating slope. Like Ceramic 5, it is a highly oriented material and must be magnetized in the direction of orientation."
- "Ceramic 8 is an excellent choice wherever magnet length is at a minimum or where the magnetic circuit is subject to severe demagnetizing fields. Some typical uses include holding magnets, motors, reed switches, and Hall-Effect devices."
- "CERAMIC 1 MAGNETS are not oriented during manufacture but will exhibit slightly greater magnetic strength along the direction of the pressing (along their shortest dimension)."
