The Iron-base nanocrystalline  are composed of iron, silicon, boron and small amounts of copper, molybdenum, niobium, etc., of which copper and niobium are essential elements for living nanocrystalline structures. They were first fabricated into amorphous ribbons, which were then appropriately annealed to form a mixture of micro-crystalline and amorphous structures.Such material is not o...

Silicon steel sheet is a ferrosilicon soft magnetic alloy with extremely low carbon content, general silicon content is 0.5-4.5%. The addition of silicon increases the resistivity and maximum permeability of iron, and reduces coercivity, core loss (iron loss), and magnetic aging. Silicon Steel mainly used to make cores for various transformers, motors and generators. The performance indicators of ...
