Soft Magnetic Alloy

Hiperco 50 Alloy is an iron-cobalt soft magnetic alloy that exhibits high magnetic saturation (24 kilogauss), high D.C. maximum permeability, low D.C. coercive force, and low A.C. core loss. This alloy is produced in strip form only and contains the addition of niobium to its chemistry for grain refinement during mill processing and final heat treatment.

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 the 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 a thin sheet (strip) and coated with an insulation layer on its surface. Or use a certain method to form an oxide insulation layer on the surface, and such alloys usually adopt magnesium oxide electrophoretic coating.

1J79 is a high saturation magnetic induction soft magnetic nickel alloy, also known as perm-alloy. The corresponding grades are Ni79Mo4, E11c, malloy, permalloy, and 79HM. 1J79 has a face-centered cubic crystal structure with a lattice constant of approximately 0.355nm at a nickel concentration of approximately 80%

1J85 is a nickel–iron magnetic alloy, with about 80% nickel and 20% iron content. It is notable for its very high magnetic permeability, making it useful as a magnetic core material in electrical and electronic equipment and in magnetic shielding to block magnetic fields.Commercial perm-alloy alloys typically have a relative permeability of around 100,000, compared to several thousand for ordinary steel.
