The metal soft magnetic powder cores mainly include iron powder core, iron silicon aluminum magnetic core, high magnetic flux and MPP four series, iron silicon aluminum magnetic core (cores sdndust) is with 5. 4%, silicon 9.6%, and the rest of the alloy made of iron powder produced by a metal soft magnetic powder core. Iron silicon aluminum cores are widely used. In recent years, due to the high nickel mediated by the high cost of iron and silicon aluminum core to highlight the characteristics of this. Has become the most widely used in the soft magnetic core of the alloy series. Because of the surge in demand, which in turn prompted the production technology improvement and product quality improvement, mainly to solar and wind energy conversion, LED drive power supply, voltage regulator, hybrid electric vehicles, UPS electric system, large current sensor, switching power supply, input current, line filters, etc.. Can replace the United States (MAGNETICS) CSC, in the East, Arnold foreign iron silicon aluminum.
