Alnico Magnets, AlNiCo Magnets Alnico Magnets

Alnico is an alloy produced by mixing aluminum, nickel and cobalt with certain addition of other metals like copper, iron and titanium. Capable of producing strong magnetic field, it has an excellent linear temperature characteristics and has wide industrial applications.
As one of the members of magnets family, Alnico remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. Alnico also boasts the lowest temperature coefficient of any commercial magnet material (0.02% per degree centigrade) allowing for excellent stability over a wide temperature range.
The most efficient use of Alnico requires that it be magnetized after the magnet has been assembled with its pole pieces into the final magnetic circuit. Magnetic saturation at the end-use location requires the application of a magnetizing force 4 to 5 times greater than the coercive force of the material. For Alnico 5, a magnetizing force of 3000 oersteds (240 KA/m) is recommended. For Alnico 8, the magnetizing force should be at least 7000 oersteds (560 KA/m). The magnetizing force need be applied only momentarily. Thus, impulse magnetizers employing a capacitor discharge are commonly used. Direct current magnetizers are also effective.


Alnico Magnets, AlNiCo Magnets Alnico

As one of the members of magnets family, Alnico remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. Excellent temperature stability, high residual induction, and relatively high energies characterize Alnico materials, composed primarily of alloy of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast magnets may be manufactured in complex shaped, such as horseshoe.


Alnico Magnets, AlNiCo Magnets More About Alnico Magnets

Alnico magnets are composed of aluminum, nickel and cobalt. They offer a very strong magnetic field, second only to rare earth magnets, and are commonly available in horseshoe, cylinder, or rod shapes.
The benefits of this unique material include:

  • Flexibility in selecting the shape due to casting process
  • Can be magnetized in one or all directions

Alnico Magnets, AlNiCo Magnets Manufacturing Process

Casting or sintering process is applied for making alnico magnets. The first step involves the pouring of molten metal alloys into moulds. Later it is passed through various heat cycles. The resultant magnets have rough surface which after machining gives a glossy look. Sintered magnets are produced by compacting fine alnico powder in a press, and then sintering the compacted powder into a solid magnet. Alnico magnets can only be magnetized only in the field having magnetizing fields of about 3 kOe. Since these magnets have low coercivity they, must be protected from the adverse repelling fields as this could partially demagnetize the magnets.


Alnico Magnets, AlNiCo Magnets Magnetizing

After the tolerance magnetizing is effected. As alnico magnets are brittle, they must be protected from hard blows and handled with care. It should be magnetized in a proper magnetic field and must be prevented from the repelling fields as it is prone to demagnetization.
