Each of the wide variety of magnetic materials available requires specific storage and handling procedures for both the safety of the user and integrity of the magnet. Why handling and storage conditions are important Improperly handled and stored magnets present risks: Risk of bodily harm or injury Risk of damage to the magnet Risk of…
Choosing an appropriate magnet material is a crucial part of the design of a magnet assembly, as it will largely impact the performance of the final product. Here are a few tips from Dura’s decades of design experience to consider when selecting a material and grade for your assembly. Considerations for choosing a magnet type…
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…
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.)
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. …
