    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. Permanent Cast Industrial Alnico Ring Magnet, C Shape AlNiCo Industrial Magnets

    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 composed primarily of Aluminum,Nickel,Cobalt,Copper and Iron.
    It have very good corrosion resistence and high max working temperature,can reach 550deg.C.
    Although other materials offer greater energy and coercivity values,the high remanence and thermal stability of Alnico makes it the most cost effective material for certain applications,like generator,microphone lifting,voltmeters and measuring instruments.
    It is widely applied in high stability fields as aerospace,military,automobiles and security system.

    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.
