Eneflux Armtek Magnetics, Inc. Ceramic 1 - Standard DISC MAGNETS CM-0577

Hard Ferrite or Ceramic magnets are the most popular permanent magnets available today. They are made form a combination of either Barium or Strontium Ferrite and Iron Oxide, and exhibit a high degree of coercive strength, making them more resistant to demagnetization. They are a low-cost solution to an endless list of magnetic applications. Hard Ferrite/Ceramic magnets can be produced with either isotropic or anisotropic properties. The most common grades are C1, C5, and C8. C1 material exhibits the lowest energy product, however it is isotropic - indicating that it can be magnetized in any direction. It should be noted that slightly more magnetic strength will be realized when parts are magnetized through the pressing (usually the shortest) dimension. Grades 5 and 8 Ceramic materials are anisotropic, and must therefore be magnetized in the manufactured dimension. They exhibit high levels of magnetic force than do Ceramic 1 materials. Hard Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -40°C and +250°C. . At very low temperatures there is a risk of permanent demagnetization in magnet systems with low working points.
