Customized Alnico Ring Magnets For Motors

Alnico magnet is an acronym referring to a family of iron alloys which in addition to iron are composed primarily of aluminum (Al), nickel (Ni) and cobalt (Co), hence al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets. Before the development of rare earth magnets in the 1970s, they were the strongest type of magnet.

Customized Alnico Ring Magnets For Motors

Alnico ring magnets are good electrical conductors because of the metallic composition. When rods (diameter smaller than thickness) are being used for open circuit applications the thickness should be approximately 5 times the diameter. However, because alnico magnets are course grained they are hard and brittle and must not be drilled, conventionally machined or used as structural components.
