ABSTRACT:
The semihard magnetic alloy of the present invention consists essentially of, by weight, 17 % to 45 % chromium, 3 % to 14 % cobalt, 0.2 % to 10 % titanium and balance substantially iron and has a residual magnetic flux density of 7,000 Gauss or more and a coercive force of 100 to 600 Oersted. Said alloy is produced by solution treating an alloy having the above-indicated composition at a temperature of 650.degree. C to 1,200.degree. C, and then either keeping the solution-treated alloy at a temperature of not higher than 650.degree. C for a given period of time and repeatedly aging said alloy in multi-stage at gradually lowered temperatures, or cooling the solution-treated alloy continuously from a temperature of not higher than 700.degree. C down to at least 550.degree. C at a rate of not higher than 50.degree. C per hour.
