Abstract
PURPOSE: To provide the title alloy for a magnetic head by restricting the Si, Al and Fe contents of Ti- and Cr-added Sendust alloy to specified ranges.
CONSTITUTION: In case of a compsn. with a magnetic flux density B10>5000G, an actual permeability μe>5000 and a coercive force Hc 0.07W0.1Oe, it is within the range connecting points (Si 5.6%, Al 11.3%), (Si 6.9%, Al 8.0%), (Si 8.4%, Al 6.5%), (Si 8.9%, Al 6.5%), (Si 8.8%, Al 8.0%) and (Si 8.4%, Al 9.2%) in a three-component phase diagram considering the total amt. of three elements Si, Al and Fe to be 100, and Cr and Ti are added by 2.5W3.5% and 0.5W2.5% of Si+Al+Fe, respectively. In case of a compsn. with B10>5000G, μe>7000 and Oe 0.05W0.07 it is within other range.
USE: Magnetic heads for broadcasting and home video tape recorders.
