Abstract
The commercial scale production of Fe-6.5wt% Si sheet has been successfully developed. Fe-6.5wt% Si sheets ranging in thickness from 0.1 to 0.5 mm can be manufactured in coil form with a maximum width of 400 mm.
The following magnetic properties have been achieved.
-
1.
The maximum permeability is about 10 times higher than that of the conventional nonoriented silicon steel, and could be doubled by magnetic field annealing.
-
2.
The core losses are less than half of the conventional nonoriented silicon steel’s, and even less than the grain oriented silicon steel’s at a frequency range of over 400 Hz.
-
3.
The coefficient of magnetostriction is extremely small (6 x 10-7). It is less than one-tenth of the conventional nonoriented silicon steel’s.
Fe-6.5wt% Si sheet should be used extensively as an electric and electronic material, owing to its own supreme soft magnetic properties. For example, this sheet is good for use in motor cores or high frequency transformer cores, supreme magnetic shields, and so on.
The details of the magnetic properties of Fe—6.5wt% Si sheet and some applications to electric devices are described.
