Isotropic Ferrite Magnets: Isotropic magnets include bond magnets using quick-cooled thin alloy as the raw material and isotropic ferrite magnets, but their magnetic characteristics are inferior to those of Anisotropic Ferrite Magnets. Rare earth sintered magnets can not be made isotropic. characteristic  The powder metallurgy method has low remanence and low recovery magnetic permeability. High coercivity, strong anti-demagnetization ability, especially suitable for dynamic working conditions of magnetic circuit structure. Hard and brittle material, can be used for emery tools for cutting processing. The main raw material is oxide, so it is not easily corroded. Operating temperature :-40℃ to +200℃.  Ferrite magnets are divided into anisotropic (heterotropic) and isotropic (isotropic). The magnetic properties of the isotropic sintered ferrite materials are weak, but they can be magnetized in different directions of the magnet. Heteromorphi…
