Abstract
The invention discloses a copper magnesium zinc material with high permeability and the application thereof. Fe2O3, MgO, ZnO and CuO are mixed, calcined and added with auxiliary materials, and then the mixture is shaped by pressing after sand grinding, drying and granulating so as to obtain the copper magnesium zinc material. The copper magnesium zinc material with high permeability is low in production cost, has the performances of high permeability and the like, and the material can be widely applied to the power parts of cathode ray indicators, liquid crystal display, plasma display, digital cameras and other electronic equipments and communication equipments.
