Regular readers of this blog likely already know that Dura Magnetics designs and manufactures comprehensive magnetic solutions for a wide variety of industries. As part of this, we are sometimes called on to perform design and manufacturing on projects tied to Aerospace and Defense contract work. Oftentimes, the magnets and magnetic assemblies used in these projects have technology export restrictions.Read More
As an AS9100 certified magnet supplier, Dura Magnetics must continually ensure that our business and manufacturing practices properly follow the requirements set forth by the standard. With AS9100C being phased out and becoming fully replaced with the revised AS9100D standard on September 15, 2018, we have already taken the appropriate steps to ensure compliance with this standard before its final implementation date.
We are proud to announce that Dura Magnetics is now an AS9100D certified company.Read More
The magnetic cup and base assembly is a simple, but very useful, magnetic assembly. The magnetic base allows for it to be attached to most ferrous surfaces, while the steel cup allows for several different attachment possibilities…Read More
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.)Read More
Many times, we are asked about the effects of thermal cycling on rare earth permanent magnets, but there is not a simple rule of thumb to offer. From a first order standpoint, thermal cycling will degrade the performance of rare earth Neodymium Iron Boron and Samarium Cobalt magnets. There are two primary mechanisms which drive this degradation. One occurs quickly, and the second occurs over a long period of time…Read More
After several months of programming, testing, and polishing, we have now made our interactive Demagnetization / Permeance Coefficient (Pc) calculator available for use on our website. This powerful tool calculates the Permeance Coefficient for a given magnet based on the magnet grade, shape, dimensions, and operating temperature specified…Read More
