Ferrite magnet 80.04

rectangularanisotropicisotropic

Permanent rectangular ferrite magnet AF 04 Ferrite magnet Isotropic or anisotropic ferrite magnets are rust resistant ceramics and have a dark brown color, obtained through a metallurgic procedure of pressing and sintering powders. Ferrite is a hard material but sensitive to shocks and its strength is highest when the magnet is in contact with a mild steel, that is clean and thick enough. The strength is reduced when in contact with Alloy steels (cast Iron -30%), due to air-gap or a high temperature (-0.4% per degree starting at 20°C). Ferrite magnets are not machinable, they can not be cut or drilled. The mounting is done with glue. Magnetized depending on thickness.
