AlNiCo magnets are a type of permanent magnet made from aluminium, nickel, and cobalt, known for their high magnetic strength, excellent temperature stability, and corrosion resistance. Like all magnets, they have advantages and disadvantages that should be considered when selecting them for use in various applications. Here are some of the advantages and disadvantages of AlNiCo magnets:
High magnetic strength: AlNiCo magnets have excellent magnetic strength, making them ideal for applications that require strong magnetic forces.
High-temperature stability: These magnets are highly resistant to temperature changes and can maintain their magnetic properties at high temperatures of up to 500°C.
Corrosion resistance: AlNiCo magnets are highly resistant to corrosion and do not require coating or plating.
Good resistance to demagnetisation: They have good resistance to demagnetisation, meaning they can maintain their magnetic strength for long periods of time.
Limited shape and size options: AlNiCo magnets have limited shape and size options compared to other magnets such as neodymium magnets.
Brittle: They are brittle and can easily crack or break if dropped or subjected to impact.
High cost: AlNiCo magnets are relatively expensive compared to other magnets, such as ferrite magnets.
Handling: These magnets are relatively strong and can be challenging to handle, requiring care and caution when being installed or removed.
Alnico magnets are known for their inherent corrosion resistance. While Alnico is frequently commended for its robust resistance to corrosion, the extent of this resistance is contingent upon both the Alnico grade and the specific chemicals to which it is exposed. Due to its trace free iron content, Alnico might display susceptibility to surface corrosion in watery environments. However, it boasts exceptional resistance when interacting with substances like motor oil, organic solvents, petrol, and alcohol.
Furthermore, Alnico displays commendable resistance against dilute organic acids and hydrogen peroxide, but prolonged exposure to salt water, potent alkali solutions, or inorganic acids may induce corrosion over time. For enhanced protection, options are available to layer Alnico with protective substances such as Ni, Zn, or paint.
While not always deemed essential, protective or aesthetic coatings are occasionally applied to Alnico magnets. A prevalent choice is a distinctive red hue, leading many to colloquially refer to Alnico magnets as 'Red Magnets'. It's noteworthy that ferrite magnets in pot magnet assemblies, also sometimes don a red exterior and share this name. Other colour variants, including black, can be opted for Alnico upon request.
