Alnico materials (composed predominantly of aluminum, nickel, and cobalt with minor amounts of other elements including titanium and copper) permit design latitudes providing high indications, high energies and relatively high coercivities. Alnico magnets are characterized by excellent temperature stability and good resistance to demagnetization from vibration and shock. Alnico magnets offer the best temperature characteristics of any standard production magnet material available. They can be used for continuous duty applications where temperature extremes up to 930F can be expected.
The Characteristics of Alnico Magnet:
*Small changes in magnetic properties to temperature effects
*Maximum working temperature can be as high as 450oC~550oC.
*Low coercive force.
*Strong corrosion resistance capability, no coating needed for surface protection.
• Suitable for small volume magnets with complex shape
• Compact crystal, high intensity
• Regular shape, precision size
• Even elements, stable performance
• Suitable for compound magnet
• Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.
