Abstract (en)
[origin: EP1918407A1] The soft magnetic alloy contains cobalt (in weight%) (10-22), vanadium (0-4), chromium (1.5-5), manganese (1-2), molybdenum (0-1), silicon (0.5-1.5), aluminum (0.1-1), and remainder of iron. The soft magnetic alloy contains cobalt (in weight%) (10-22), vanadium (0-4), chromium (1.5-5), manganese (1-2), molybdenum (0-1), silicon (0.5-1.5), aluminum (0.1-1), and remainder of iron. The sum total of silicon and aluminum content is 0.6-2 weight%. The sum total of chromium, manganese, molybdenum, silicon, aluminum and vanadium content is 4-9 weight%. The soft magnetic alloy further contains nitrogen (200 ppm or less), carbon (400 ppm or less) and oxygen (100 ppm or less) as impurities. An independent claim is included for manufacture of soft magnetic alloy.
