What is the Fe-based amorphous alloy?
Amorphous alloy, glass or metal, it is appeared in the 1970 s a new type of material, is the use of rapid cooling technology, the liquid steel for a molding thickness of 30 microns thin band, the solid alloy (strip) is different from the atoms in the crystal structure of regularly arranged cold-rolled silicon steel materials, it is this alloy the amorphous structure of atoms in a random arrangement, It has the characteristics of narrow B-H circuit, high magnetic conductivity and low loss. At the same time, the irregular arrangement of the atoms in the amorphous alloy limits the free passage of electrons, resulting in a resistivity 2-3 times higher than that of the crystal alloy, which also helps to reduce the eddy current loss. The transformer core made of amorphous alloy can reduce the no-load loss by about 75% compared with the traditional transformer made of silicon steel sheet, which makes the amorphous alloy transformer have a very significant effect of energy saving and environmental protection. When the amorphous alloy transformer core is used in oil-impregnated transformer, it can obviously reduce a variety of harmful gases. Therefore, more and more manufacturers use amorphous alloy as the raw material of transformer core.
