Soft Magnetic Alloy Stainless Steel Bar 1j50 75mm Diameter Round Ni - Fe 65mm

1J50 is a Ni-Fe soft magnetic alloy, and its main compositions are about 50% Ni, 48% Fe and other micro-elements. This alloy is characterized by high magnetic permeability, higher saturation induction density, etc. As a soft magnetic material used in alternating current, vortex and loss are induced inside the material due to the alternating magnetization. The smaller the resistivity and the greater the thickness of the alloy, and the higher frequency under the alternating magnetic field, the greater the eddy loss and the more the decrease of the magnetic performance. So, the material must be manufactured as thin sheet (strip) and coated with insulation layer on its surface. Or use certain method to form oxide insulation layer on the surface, and such alloys usually adopt magnesium oxide elecrophoretic coating.
