RIGID BELT CORE Russian patent published in 1995 - IPC

FIELD: metallurgy. SUBSTANCE: core, designed for using in noise suppressing filters and other apparatus of radioelectronic equipment, should have a high value of magnetic field, in limits of which the core has practically constant permeability. The rigid belt core, having at least one slit, is made of a ferrum base alloy, containing (at.): copper (0.5-2.0) or at least one component, selected from a group, including niobium, tantalum, tungsten, molybdenum, chrome, vanadium, in quantity (2-5); silicium (5-18); boron (4-12) ferrum the balance. A structure of the alloy includes at least 50% of crystals with size 100 nm. The core has in its interturn space a hardened non-organic adhesive. EFFECT: enhanced quality of core of such alloy, namely its constant permeability in range of high magnetic field. 4 cl, 1 dwg
