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 […]

Magnets in the News: Rare Earth Metals a Last Minute Deletion from China Tariff List

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….

Magnet Price in a Volatile State: How Cobalt & Neodymium Demand Impacts Magnet Pricing

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 […]

Dura Magnetics – ITAR Registered and Compliant

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.

Dura Magnetics Is Now an AS9100D Certified Company

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.

Choosing the Correct Cup & Base Magnetic Assembly

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…

What is Alnico 8 and How is it Different from Alnico 5 Magnets?

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.)

Thermal Cycling: Effect of Temperature on Rare Earth Magnets

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…
