Ring shape Speaker y35 ferrite magnet
Hard ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent magnets for applications such as refrigerator magnets, loudspeakers, and small electric motors. 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 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 (heterot…
