摘要: A method of producing permalloy cores comprising the steps of applying an annealing separator coating 0.1 to 50 µm thick to at least one surface of wide permalloy strip, slitting the wide permalloy strip to a final width, winding or punching the final width strip, and annealing the strip at a temperature in the range 1000 °to 1300°C, and a permalloy core producible with this method. The method allows the efficient manufacturing of permalloy cores with highly stable magnetic properties.
