FIELD: magnetically hard alloys. SUBSTANCE: alloy that falls into Fe-Ni-Al-Co-Cu-Ti system has rather narrow range of components and is doped, in addition, with sulfur, boron, and mish metal or lanthanum, mas.%: Co, 17.0-17.9; Ni, 14.0-16-0; Al, 7.0-8.0; Si, 1.0-1.6; Ti, 0.2-0.6; S, 0.05-0.3; B, 0.001-0.1; mish metal or lanthanum, 0.001-0.2. Alloy is classed as pseudoferrite material; its residual flux density Br = 1.28-1.32 T; coercive force Hc = 45-48 kA/m; energy product (BH)max= 37-39,5 kJ/m3. EFFECT: improved hardenability of alloy.
