Alnico magnets are widely used in industrial and consumer applications where strong permanent magnets are needed. In many applications they are being superseded by rare-earth magnets, whose stronger fields (Br) and larger energy products (B·Hmax) allow smaller-size magnets to be used for a given application. Extremely resistant to demagnetization

Some examples are:

• Motoare electrice
• Electric guitar pickups
•  Microphones
•  Senzori
•  Loudspeakers
• magnetron tubes
• cow magnets

The majority of magneții AlNiCo are cast type. Cast AlNiCo magnets are manufactured by conventional foundry processes. AlNiCo alloys with different composition are melted and poured into the resin bonded sand molds, then solidified material with a rough surface will undergo heat treatment and cooling process. Cast AlNiCo magnets can be divided to the isotropic form and anisotropic form base on whether apply the magnetic field to orient magnets during the cooling process. For cast AlNiCo magnet, its anisotropy is a kind of shape anisotropy which associated with elongated Fe-Co particles in a Ni-Al matrix aligned parallel to the magnetic field during spinodal decomposition of the alloy. Therefore, material will be machined to specific geometry and tolerance after heat treatment process.

Sintered AlNiCo magnets are manufactured by powder metallurgy technology which similar with other sintered magnets. Its overall magnetic performance is slightly low than cast AlNiCo magnets, thus not commonly used like the latter. Sintered AlNiCo magnets are well adapted for small-sized, thin, light, and complex shaped magnets. Beside high dimensional accuracy and tight tolerance, It also has superior mechanical strength and machinability. Viewing from the production, sintered AlNiCo magnets have higher utilization ratio of material, lower composition segregation and magnetic performance fluctuation compared to the cast AlNiCo magnets.
