Title:
Fe-Ni BASED PERMALLOY, ITS PRODUCTION METHOD AND CAST SLAB
Document Type and Number:
Japanese Patent JP2002173745
Kind Code:
A
Abstract:
To improve the magnetic properties of a PB material and a PD material to rank up respectively to those equal to the magnetic properties of a PC material and a PB material, and to provide a PC material which has more improved magnetic properties, and can be applicable to higher sensitivity and frequency use.
The Fe-Ni based permalloy has a composition containing, by weight, 30 to 85% Ni, ≤0.015% C, ≤1.0% Si, ≤1.0% Mn, ≤0.01% P, ≤0.005% S, ≤0.006% and ≤0.02% Al, and the balance Fe and inevitable impurities. In the alloy the content of Ni segregation in the rolling stock subjected to homogenizing heat treatment i.e., CNis is ≤0.15 wt.%.
