Why do the cores used in the inductors have the most iron core?

The magnetic core of the energy storage inductor is composed of a manganese-zinc core, an iron powder core, a nickel-zinc core, a tantalum steel core, a ferrosilicon core, an iron-nickel core, a ferrite, etc., but at present, the most used iron powder core . So why can the iron powder core stand out among the many materials?
Iron powder core is a popular saying in the electronic component industry. From a chemical point of view, it should be called ferroferric oxide. The production method is as follows: a soft magnetic material which is obtained by high-purity reduced iron powder or base iron powder through surface insulation coating, binder mixing, and various processes. Because of its good DC superposition characteristics and electromagnetic compatibility, good temperature stability, high frequency characteristics and insulation, and simple production process, the production cost is also the lowest among all kinds of metal magnetic powder cores. Therefore, it is the most widely used and widely used among the magnetic powder cores of various metals.
To store the magnetic powder core material on a daily basis, it needs to be stored in an enclosed space free from oil, solvents, dirt, dust and acidic liquids, and the storage time should not be too long. Do not open the original product packaging until it is used. Use it as soon as possible after opening the package to prevent the product from rusting.
