As detailed in IQS Directory’s article, “Alnico Magnets,” alnico magnets are highly versatile permanent magnets made from a blend of aluminum, nickel, iron, cobalt, and other elements. With magnetic strength 5 to 17 times greater than naturally occurring magnets, such as magnetite, these magnets are widely used in applications requiring high-temperature performance and corrosion resistance.
First introduced in the 1930s, alnico magnets remain a top choice in permanent magnet motors and sensor applications due to their ability to retain magnetic properties up to 930°F (500°C) and their resistance to demagnetization. They cannot be cold worked and are produced through sintering or casting, with casting offering superior performance and the flexibility to create complex shapes.
Alnico magnets’ unique properties make them indispensable in industries demanding durability and reliability in harsh environments. Their stable temperature coefficient and high residual induction allow them to deliver consistent performance across various applications.
