Isotropy AlNiCo Alloy
General Introduction1, Alnico alloys make strong permanent magnets, and can be magnetized to produce strong magnetic fields.
2, Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger.
3, Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth's magnetic field.
4, Some brands of alnico are isotropic and can be efficiently magnetized in any direction.
5, Other types, such as alnico 5 and alnico 8, are anisotropic, with each having a preferred direction of magnetization, or orientation.
6, Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types.
