Hengdian Kim aka magnet magnet magnetic Factory ---- refers to the presence of a magnetic field around the object or material and their own internal, is divided into two major categories of natural and man-made. Artificial magnets usually made of a metal alloy, having a ferromagnetic. Can be divided into "non-permanent magnet" and "non-permanent magnet" Local magnetic steel Which is good, that is, "magnetically hard" and "soft." Natural magnet main ingredients: iron oxide, the chemical formula Fe3O4 magnetic steel wholesale local, often referred to as "magnetic iron oxide." Having a magnetic black crystals. Ferrous oxide and iron oxide compounds can be regarded as. Because the iron oxide crystals in the presence of two different valence states of ions, of which one third is Fe2 + local magnetic steel, two-thirds of Fe3 +, is a complex compound. It is insoluble in water, it can not react with water. React with acids, alkali-insoluble. The main system for high-temperature magnetic primer and topcoat, magnetic materials for the electronics industry, but also for rust in the construction industry. Hengdian Kim Dae-magnetic NdFeB magnet factory ----- What made out of NdFeB magnets are made out of what? First of NdFeB magnet manufacturers need first to understand that it is necessary to contain alloy materials crushed into particles, these particles come together forming, and then sintered. Then cut off into desired size to complete. Of course, high-quality local magnetic steel, in the actual production of high-quality NdFeB magnets is not so simple. Not only to the unity of 3 ~ 5μm particle size, but also pay attention to the uniformity of shape, but also consider the heating methods such as sintering, it takes a lot of work to make. Local magnetic steel Inner local suppliers _ _ Kim Dae-magnetic magnetic steel plant smiling service is provided by a large magnetic Hengdian gold plant. Hengdian Kim Dae-magnetic Factory (www.jjdct.cn) strong, credible, Zhejiang Jinhua electronics, electrical equipment manufacturing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Kim Dae-magnetic factory and you hand into the brilliant, for a better future!
