Method of manufacturing a low magnetic loss metal tape with biaxial texture

A manufacturing method of low magnetic loss metal tape with biaxial texture comprising the steps of:

• (A) processing a cathode with electrolytic polishing to smooth the surface of the cathode;
• (B) dipping the cathode, for at least two seconds, in a solution containing one of 10 mol or less hydrochloric acid, 10 mol or less nitric acid, 10 mol or less sulfuric acid, 10 mol or less acetic acid, 10 mol or less chromic acid, 10 mol or less potassium dichromate, 10 mol or less fluoric acid, 10 mol or less lithium hydroxide, 10 mol or less sodium hydroxide, 10 mol or less potassium hydroxide, 10 mol or less ammonia water, 10 mol or less hydrogen peroxide, or a combination of two or more components;
• (C) washing and drying the cathode;
• (D) forming a nickel layer with biaxial texture on a surface of the cathode rotating in an electroplating bath, the cathode having a single crystalline or similarly high orientation, and the electroplating bath including an anode made of high purity nickel;
• (E) delaminating the nickel layer formed on the surface of the cathode to form a nickel layer tape and washing the nickel layer tape in a water bath;
• (F) forming a non-magnetic metal layer on the washed nickel layer tape on a second cathode in a plating bath with a non-magnetic metal solution to form a nickel/non-magnetic metal layered tape;
• and
• (G) delaminating the nickel/non-magnetic metal layered tape from the second cathode and winding the nickel/non-magnetic metal layered tape.
