Alnico Magnets
Alnico magnets are permanent magnets made primarily from an alloy of aluminium, nickel, cobalt, and iron. This unique composition gives Alnico magnets their distinct magnetic properties, enabling them to maintain a strong magnetic field even in challenging conditions. The process of magnetisation involves aligning the magnetic domains within the alloy, which results in a powerful and stable magnetic field. Alnico magnets are often preferred in applications requiring high temperature stability, as they can withstand extreme heat without losing their magnetic strength.

Alnico Frequently Asked Questions
We’re always here if you need us. If your question isn’t covered below, please reach out — we’ll gladly help you find the right answer.
Q:
What applications are Alnico magnets commonly used in?
A:
Alnico magnets are often used in various applications, including electric motors, sensors, and loudspeakers, due to their strong magnetic properties and excellent temperature stability.
Q:
How are cast alnico magnets different from sintered alnico magnets?
A:
Cast alnico magnets are produced through a casting process, resulting in a denser and more durable magnet, while sintered alnico magnets are made through a powder metallurgy process, which can lead to a more brittle product.
Q:
Why are Alnico magnets still popular in today’s technology?
A:
Alnico magnets are still popular because they were historically some of the strongest magnets available and they continue to provide reliable performance in many industrial and consumer applications.
Q:
