Understanding Alnico Magnets and Their Benefits
What are Alnico Magnets?
Alnico magnets are a type of permanent magnet made from an alloy of aluminum (Al), nickel (Ni), and cobalt (Co), along with iron and other trace elements. These magnets are renowned for their ability to maintain magnetic strength even at elevated temperatures, making them invaluable in various industrial applications. They come in two primary forms: cast and sintered, each possessing unique properties that cater to different applications.
The term “Alnico” reflects both the composition and the characteristics of these magnets. Unlike other types of magnets—such as neodymium or ferrite—Alnico magnets can withstand higher temperatures (up to 550 °C) without losing their magnetism. This resistance to demagnetization is one of the significant advantages that Alnico magnets offer. Furthermore, they can be machined into specific shapes, allowing for versatility in applications ranging from electric motors and sensors to loudspeakers and magnetic instruments.
