Alnico magnetic material is an alloy of aluminum-nickel-cobalt which possesses an excellent temperature stability and high residual induction.

Alnico Magnets Overview

Alnico magnetic material is an alloy of aluminum-nickel-cobalt which possesses an excellent temperature stability and high residual induction. However, its low coercive force limits its applications in many cases. Casting and sintering are two major processes used to manufacture the Alnico magnets.

Key Advantages

Cast Alnico Magnets:

Excellent temperature stability
Strong corrosion resistance
The maximum working temperature is up to 500°c
Excellent capacity
High density and magnetic properties
Shorter production lead time
Temperature factor of Br is the smallest among all the permanent magnets
Cast Alnico magnets can be produced in relatively complex shapes
Tooling for cast Alnico magnets is relatively low, since sand molds are generally used for the casting process.

Quick Leads

Density-7.34 g/cm3
Manufacturing process - casting (most common), or sintering.
Various shapes- blocks, bars, discs, rings, horseshoes, cylinders, etc.
Wide range of grades- from about 0105 to 0519. (First 2 digits represent BH.max, and second two digits represent Intrinsic Coercivity, Hci.)
Saturation magnetizing field required - about 5kOee.

Common Applications

Holding magnets Separators Sensors Security systems MRI Relays Magnetos
