Alnico
Some types of alnico magnets are isotropic (properties are same in all directions) and can be properly magnetised in all directions. Other types like alnico 5 and alnico 8 are anisotropic (properties change when direction changes) have a preferred direction (one direction would be better than other directions) for magnetisation. Anisotropic alnico alloys will make stronger magnets in their preferred direction than an isotropic alnico alloy.
