IRON-BASE AMORPHOUS ALLOY INCREASED IN MAGNETIC FLUX DENSITY AND REDUCED IN IRON LOSS

摘要

PURPOSE:To produce an iron-base amorphous alloy increased in magnetic flux density and reduced in iron loss by preparing an iron-base amorphous alloy consisting of specific percentages of Fe, B, Si, Mn, and Co. CONSTITUTION:An iron-base amorphous alloy having a composition represented by chemical formula FexBySizMnaCob is prepared. In this formula, x=70 to 80%, by atom, y=7 to 15%, z=4 to 17%, a=0.2 to 3%, b=5 to 10%, and x+y+z+a+b:100. By this method, the iron-base amorphous alloy, improved in magnetic flux density and reduced in iron loss to a greater extent, can be produced.
