Strong Magnetic Large Ring Ferrite Magnets For Speaker

Strong Magnetic Large Ring Ferrite Magnets For Speaker Anisotropic ferrite magnet The Anisotropic Ferrite Magnets have a preferred direction of magnetisation within the structure and have strongest magnetic properties along that direction (they are more powerful than isotropic ferrite magnets). There are two chemical varieties of ferrite magnet. 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 propert…
