AlNiCo Magnets

AlNiCo Magnets

Alnico magnets are permanent magnets mainly composed of aluminum, nickel and cobalt, but may also contain copper, iron and titanium. Alnico magnets are available in isotropic or anisotropic versions. Isotropic varieties can be magnetized in any direction, while anisotropic Alnico magnets can only be magnetized in a predefined direction and have a higher magnetic performance.

Alnico magnets are permanent magnets mainly composed of aluminum, nickel and cobalt, but may also contain copper, iron and titanium. Alnico magnets are available in isotropic or anisotropic versions. Isotropic varieties can be magnetized in any direction, while anisotropic Alnico magnets can only be magnetized in a predefined direction and have a higher magnetic performance.

Although Alnico magnets have been replaced by stronger rare earth magnets, they are still widely used in the manufacture of sensors, relays and high temperature equipment. Alnico magnets play a critical role in all electro permanent magnetic tables and lifting equipment because Alnico has a high magnetic strength and a low resistance to demagnetization and re-magnetization. If coils of wire are wound around Alnico magnets, they can be easily magnetized and demagnetized by electricity flowing through the coils. Lifting and fixing equipment of 100 tons per square meter can be opened and closed in 0.2 seconds thanks to Alnico magnets.

Advantages;

  • High corrosion resistance
  • High physical strength (does not crack or break easily)
  • High temperature resistance (up to 540°C)
  • Electrical conductivity

Disadvantages;

  • They can be easily demagnetized (magnets need to be stored with a shield to allow the magnetic field to continue to flow around the magnet)
  • It has weaker magnetic attraction force than new generation Neodymium magnets

We offer you the widest variety of AlNiCo magnets.
