When creating custom magnets or magnetic assemblies, ensuring the final measurements properly align with the CAD model is imperative. At Dura Magnetics, we employ a coordinate measuring machine (CMM) during our quality inspection process. The CMM provides efficient, accurate, and consistent measurements of multidimensional shapes to ensure our customers receive conforming product every time. A…
In January 2020, the John S. McCain National Defense Authorization Act was instituted, adding neodymium to the list of DFARS materials. Through this act, neodymium is prohibited for government defense contracts if sourced from China, Russia, North Korea, or Iran. To be compliant with this update to the Defense Federal Acquisition Regulation Supplement (DFARS), it…
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…
According to The New York Times, recent tariffs imposed on imported goods from China are meant to pressure the country to change its current trade practices that are negatively impacting American businesses. However, as the deadline approached for the final agreement in late September 2018, the US administration decided to remove nearly 300 product lines from the list due to specific objections by American companies. One of the product lines deleted from the list of tariffs was rare earth metals. Rare earth elements are currently used in myriad products worldwide including magnets, radar, high tech products, vehicles, and more….
Two recent discoveries – one related to the re-use of magnetic materials obtained from discarded computer components, the second a potential new trove of rare earth elements found in deep-sea mud near the coast of Japan, may reshape the magnetic marketplace…
As global demand for Cobalt and Neodymium continues to rise, magnet manufacturers and fabricators have to deal with a volatile pricing situation. Cobalt and Neodymium are key raw materials used in the manufacturing of rare earth magnets. As you might guess, Neodymium is an essential component of Neodymium magnets, while Cobalt is an essential component…
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.
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.
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…
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.)
