Abstract
PURPOSE: To provide an alloy described in the title having excellent machinability and excellent magnetic property equal to that of A1 nico alloy, by addn. of a prescribed amount of Pb as a subcomponent to an alloy contg. Cr, Co, and principally Fe.
CONSTITUTION: To an alloy comprising 17W45% particularly 23W35% Cr, 8W 20% Co, and balance being principally Fe is added 0.01W1.0% Pb as a subcomponent. The alloy thus prepared is solution-treated at a temp. 650W1,300°C, particularly 850W1,085°C. The alloy having been solution-treated is treated in magnetic field at a temp. 570W670°C, particularly 590W650°C, then heated to a temp. 200°C or less lower than the temp. for the treatment in magnetic field, and is cooled at a controlled rate to be aged, hereby desired Fe-Cr-Co type permanent magnet is manufactured.
