Cast AlNiCo Cylinder Magnet for ABS Sensors

Alnico Magnet is a kind of alloy which is comprised of aluminum, nickel, cobalt, iron and other microelements. There are two  different  manufacturing processs for ALNICO: Cast and Sintered. Cast ALNICO can be made into many sizes and shapes, and better magnetic properties than Sintered ALNICo. Whereas Sintered ALNICo is usually restricted to smaller size, but better blank size tolerance and processablity. ALNICo magnet has strong anti-corrosion property which need not plating processing on the surface.

Cast AlNiCo Cylinder Magnet for ABS Sensors

Alnico magnets exhibit excellent temperature stability, high residual induction, and relatively high energies. Alnico is composed primarily of alloys of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast alnico magnets may be manufactured in complex shapes, such as horseshoes, not possible with other magnet materials. Sintered Alnico magnets offer slightly lower magnetic properties but better mechanical characteristics than cast Alnico magnets.

The AlNiCo magnet has been used in wheel speed sensor for a long time. The AlNiCo magnet can be classified as cast AlNiCo magnet and sintered AlNiCo magnet. For wheel speed sensor magnet, the sensor manufacturers will use cast type.

Alnico Magnet Manufacturing Methods

Alnico magnets are manufactured through either casting or sintering processes. Cast Alnico magnets are 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 magnets are manufactured by compacting fine Alnico powder in a press, and then sintering the compacted powder into a solid magnet.
