MICROCRYSTALLINE THIN STRIP FOR MAGNETIC MATERIAL WITH HIGH MAGNETIC PERMEABILITY,PROCESS FOR PRODUCING SAME,AND THIN STRIP PRODUCTS

Document Type and Number:

WIPO Patent Application WO/1980/002620

Kind Code:

A1

Abstract:

A microcrystalline thin strip for magnetic material with high magnetic permeability, which contains 7.0 to 9.6% Si, 5.5 to 7.5% Al, 0.3 to 3.0% Mo, 0.3 to 4.0% Ni, 0 to 0.5% Ca, the balance being substantially Fe, and which has a tensile strength of 35 kg/mm2 or more and a bending failure strain of 8 x 10-3 or more. This thin strip can be produced with ease, and has enough tensile strength and flexibility to be worked into various magnetic materials.
