https://www.ktmagnet.com/products/ferrite-magnets/ Ferrite Magnets Ferrite, as a metal oxide, has high hardness and brittleness, and can be classified as "soft magnet" or "hard magnet" based on its low or high coercivity. Its high resistivity, dielectric properties, and magnetic permeability make it widely used in non-metallic magnetic materials in the high-frequency and weak current fields.All Rights Reserved
