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. Alnico delivers impressive flux density at an economical price. It boasts the lowest reversible temperature coefficient of any standard commercial magnet material (0.02% per degree centigrade) allowing for excellent stability over a wide temperature range. Alnico is also inherently corrosion resistant.

Types of Alnico Magnets
On the basis of manufacturing process and application alnico can be grouped into following types:
Alnico magnets can be fabricated into many shapes and types:
Alnico horseshoe magnets
AlNiCo rod magnets uncoated
Alnico's are the strong magnets which can produce strong magnetic fields.
Excellent resistance to corrosion
They have superior thermal stability
These magnets have some of the highest curie points of any magnetic material ranging around 800oC
Some type of Alnico's are isotropic
They have high magnetic flux density
Alnico magnets have applications in the following areas:
Electric guitar pickups
Automotive and electronic sensors
Hall effect sensors
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.
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.
