Alnico magnets: Design, fabrication and compliance considerations

While some rare-Earth materials have surpassed Alnico in popularity, it remains a key magnet material vital to certain industries, particularly those required to maintain DFARS compliance. At Dura Magnetics, we have USA-produced Alnico raw material available upon request. While the material itself poses a somewhat difficult and unique machining challenge, our team has the experience […]

How is Alnico 8 Different from Alnico 5?

Alnico is a common and very commercially mature magnet alloy comprised of Aluminum, Nickel, Cobalt, Titanium and Iron. (There are also small amounts of various other elements including, but not limited to; copper, silicon, columbium, and zirconium.)

Alnico has a very high Residual Induction (Br). This characteristic of a magnet offers a sense of how large/strong of a magnetic field a particular magnet alloy can generate. (Typically the higher the Residual Induction the larger, more dense the magnetic field can be generated by a magnet.)

Alnico Magnets for High Heat Applications

Since its incorporation in 1961, Dura Magnetics has been a leading manufacturer of fabricated alnico magnets.  Alnico is an acronym used to reference the three primary elements used in the manufacturing process; aluminum, nickel, and cobalt.  Prior to the 1970’s and the advent of rare earth magnets, alnico was the strongest type of permanent magnet.  […]
