Metal magnetic materials and non-metallic magnetic materials how to distinguish
Magnetic materials in the production of modern industrial equipment in the role of growing, according to the different performance, magnetic materials can be divided into metal magnetic materials and non-metallic magnetic materials two categories, then what is the difference between them?
First of all, metal magnetic materials, as the name suggests, is made of metal alloy or metal compounds made of magnetic materials. Most of the metal magnetic materials are based on iron, nickel or cobalt, and then add some other elements made of high temperature. This kind of magnetic material plays an important role in many places, such as high temperature, low frequency, high power. In addition, the metal magnetic material can be specifically divided into hard magnetic, soft magnetic and magnetic. Soft magnetic material is easy to demagnetize, so it is used in the manufacture of electromagnets, transformers and so on. Hard magnetic material, with a strong magnetic, and is not easy to be eliminated, so hard magnetic material, also known as permanent magnet material. This kind of material is mainly used in the production of electrical equipment. Magnetomagnetic material magnetic material can be changed with the shape of the length of the material, it is used in deep electric transducers is a good choice.
Non-metallic magnetic materials, is the use of non-metallic materials, synthetic magnetic materials, where the emphasis on ferrite. The ferrite is made by mixing some of the metal oxides, and the fabrication process is somewhat similar to ceramics. Ferrite has a high permeability, high resistivity characteristics. The main application of the occasion is the electronic technology in the antenna and the inductance of the core. Non-metallic magnetic materials because of its special quality for wireless electronics technology has a very important help, many scientists are committed to the study of non-metallic magnetic materials, and strive to play its greatest role.
It can be said that the magnetic material in the electronic, information technology, machinery production, industrial production and other aspects are closely linked, in which the role can not be ignored.
