AlNiCo Magnet

Alnico magnet is an alloy magnet made from aluminum (Al), nickel(Ni), cobalt(Co), copper(Cu), iron (Fe) and other metal elements. According to the different processing technology, Alnico magnet was classified into two types: Cast AlNiCo and sintered Alnico. Cast Alnico magnet has high magnetic flux density and it can be processed into different size and shape. Sintered Alnico of simple process can be pressed directly into the size. 


Advantages of AlNiCo

1. For it's mall temperature coefficient, the magnetic performance are staunch when the temperature changes. 

2. The highest working temperature can reach 400 degrees Celsius, so it is widely used in instruments, meters, in which the requirements of high temperature stability of products. 

3. Possess a high ability in resistant to rust, so it don't need to plating processing on its surface. 

4. Cast aluminum nickel and cobalt owns a high magnetic performance, can be processed into the production of different sizes and shapes, sintered aluminum nickel and cobalt has the advantages of simple process, can be directly pressed into required size.

  • ALNiCo Block Magnet
    Alnico materials (composed predominantly of aluminum, nickel, and cobalt with minor amounts of other alnico magnetelements including titanium and copper) permit design latitudes providing high indications, high energies and relatively high coercivities.
  • ALNiCo Disc Magnet
    AlNiCo magnets are characterized by excellent temperature stability and good resistance to demagnetization from vibration and shock.
  • ALNiCo Ring Magnet
    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. alnico magnet, alnico magnets, alnico bar magnet, alnico horseshoe magnet.
