Abstract

Alloys used in the manufacture of magnetically anisotropic permanent magnets contain the following constituents: ..(i).(ii).(iii) .Co.15-42%.24%.34% .Ni.10-20%.14%.14.5% .Al.6-10%.8%.7% .Cu.0-8%.3%.4.5% .Ti.0-10%.-.5% .Fe balance to.100%.51%.35% Column (i) gives the possible percentage range of the constituents while columns (ii) and (iii) are particular examples. By controlled cooling during casting the crystal structure of the metal is arranged so that either 100-surfaces of the crystals are parallel to the axis of the magnet or alternatively so that at least one 100-direction is parallel to the axis of the rod as well as 100-surfaces. Specifications 821,624 and 852,249 are referred to.
