COBALT-BASE MAGNETIC ALLOY Russian patent published in 2002 - IPC

FIELD: metallurgy. SUBSTANCE: invention relates to cobalt-base magnetically soft alloys with low residual magnetic induction. Cobalt-base alloy of an amorphous structure comprises components in the following ratio, at.-%: iron, 1.65-5; manganese, 2-6; silicon, 2-8; boron, 10-20; cobalt, the balance. The sum of iron and manganese is 4-8 at.-% and the sum of silicon and boron is 16-24 at.-%. Alloy shows the low residual induction, high linearity degree of magnetization curve and magnetic induction value B₈₀₀ above 0.9 Tl. Alloy can be used with the enhanced effectiveness for thermomagnetic treatment in transverse magnetic field. EFFECT: improved properties of alloy. 1 tbl, 1 ex
