Abstract
An anisotropic permanent magnet comprises a ferrous alloy or sintered mass of the following composition:-Ni 10-30 per cent, Al 6-11 per cent, Co 12-30 per cent, Cu 0.5-8 per cent, Ta 0.5-10 per cent, Fe, with impurities, the balance. One or more of Si, Ag, Ti, W, V and Zr, up to 1.0 per cent in total, may also be present in the alloy or sintered mass. One or more of C, S, P, Cr, Mn, Mo may be present as impurities up to 1.0 per cent in total. Magnets produced from the material may be kept at 650 DEG -700 DEG C for 1 hour, furnace cooled to 350 DEG -450 DEG C over a period of 20-24 hours, then further cooled to room temperature and further maintained at 540 DEG -580 DEG C for about 16 hours, or the magnets may be kept at 550 DEG -600 DEG C for 24-72 hours and then at 500 DEG -550 DEG C for 24-72 hours. Specifications 439,543, 450,431, 634,686 and 634,700 are referred to.
