Permalloy Transformer Soft Magnetic Alloy 17*35*80mm Precision
alloy 1J50 Plate Ohmalloy-1J50 is a nickel–iron magnetic alloy, with about 50% nickel and 48% iron content. It is derived in accordance with permalloy. It has characteristics of high permeability and high saturation magnetic flux density. Alloy melting in a vacuum medium, cast into ingots, after hot
forging blanks made of sheet metal, and then after hot rolling,
pickling, surface treatment, cold rolling into finished products. Normal composition% |
