Electro AlNiCo Permanent Magnets,
Chuck AlNiCo Permanent Magnets,
Electro sintered alnico magnet
Excellent temperature stability, high residual induction, and relatively high energies.
Alnico is a combination of Al (aluminium), Ni (nickel), and Co (cobalt).
This development and introduction of Alnico meant that expensive electromagnets could be replaced with permanent magnets in essential devices like motors and generators.
Alnico magnets are permanent magnets that are primarily made of aluminium, nickel and cobalt.

AlNiCo magnet is composed of Aluminum, Nickel, Cobalt, and a few transition metals. They have excellent temperature stability, high residual induction, and relatively high energies. AlNiCo magnet may be manufactured in complex shapes, such as horseshoes, which is otherwise not possible with other magnet materials. They represent the most versatile magnets available.
Alnico magnet is manufactured through either casting or sintering processes. Cast magnet is manufactured by pouring a molten metal alloy into a mold and then further processing it through various heat-treat cycles. The resulting magnet has a dark gray exterior appearance, and may have a rough surface. Machined surfaces have a shiny appearance similar to steel. Sintered magnet is manufactured by compacting fine Alnico powder in a press, and then sintering the compacted powder into a solid magnet.
Machining & Tolerance:
Alnico magnet is hard and brittle, and prone to chipping and cracking. Special machining techniques must be used to machine this material. The Standard tolerances for Alnico magnet is +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.
The corrosion resistance of Alnico magnet is considered excellent , and no surface treatments are required. However, Alnico magnet is easily plated if specially required.
Magnetizing & Packing:
Alnico magnet requires magnetizing fields of about 3kOe. Because of their relatively low coercivities. Alnico magnet should be packed properly in order to assure that the magnet is not subjected to adverse repelling fields, since this could partially demagnetize the magnet.
Cast Alnico 5 is the most commonly used of all the cast Alnicos. This material is used extensively in rotating machinery, meters, instruments, sensing devices, and holding applications, to name a few.
