This product is an oil-filled sealed type, operating on the same principle as a sealed power transformer. Amorphous alloy consists primarily of iron, nickel, cobalt, silicon, boron, carbon, and other elements. It is a homotropic soft magnetic material characterized by low magnetization power, absence of structural defects that hinder domain wall movement, and an extremely thin thickness of only 0.027 mm. Consequently, its filling factor is reduced to merely 0.75–0.8, while its resistivity is significantly higher—3–6 times that of silicon steel plate—and its hardness is five times greater. Amorphous alloy exhibits exceptional sensitivity to mechanical stress.
