Ferrite magnets started in the 1950s and are widely used because they are the most economical, have good magnetic properties, and are environmentally stable. According to the raw material, it is divided into dam-based ferrite and high-coercivity strontium-based ferrite, but in recent years, barium-based ferrite has been discontinued due to environmental and health reasons.
Our company can produce both anisotropic and isotropic ferrites, and anisotropic products are 3 times higher than isotropic magnetic energy products. After incoming inspection, raw materials (mainly iron oxide, strontium carbonate) will be weighed, batched, pre-fired and then ball milled. For homosexual products, the raw materials are ground into powder and then pressed. There are two ways to produce heterosexual products: dry pressing and wet pressing. Sintering, processing and cleaning, and magnetization after molding. The magnet surface can be machined, marked or plated according to customer requirements.
