    AlNiCo magnet is ferroalloy with three main components, aluminum (Al), nickel (Ni) and cobalt (Co). It has high Curie temperature, generally is made by casting or sintering process. It has good corrosion resistance and better physical properties than ferrite. In the permanent magnet material, the cast AlNiCo permanent magnet has the minimum reversible temperature coefficient and the working temperature can be as high as 600℃ or above.
    We can provide our customers with customized Aluminum, Nickel and Cobalt products, which are highly resistant to corrosion without coating.

    Application of Casting Alnico Magnet: Automotive parts, instrumentation, electro-acoustic, electrical, teaching,guitar pickups and aerospace military and other fields
    Sintered Alnico Magnet: Instruments, meters, communications, magnetic switches and various sensors and other fields

    AlNiCo is comprised of aluminum, nickel, cobalt and iron with varying additions of other elements. There are two different manufacturering process for Alnico: Cast and Sintered. Cast alnico can be made into many sizes and shapes, whereas sintered alnico is usually restricted to smaller sizes.

    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 2 5 Cylinder Bar Magnet

    Manufacturing Process

    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.

    Excellent temperature stability up to 1,000° F; Alnico magnets are used today in high temperature applications, in applications requiring low coercivities (the ability to demagnetize and re-magnetize easily),
    High residual induction: alnico magnets can produce powerful fields in certain configurations. Alnico material does not corrode.
    Cast alnico magnets can be produced in relatively complex shapes.
    Tooling for cast magnets is relatively low, since sand molds are generally used for the casting process.
