Magnets in the News: Revival of rare-earth mining in the United States

Could U.S.-produced NdFeB be next? Rare earth elements, such as cobalt and neodymium, are highly valued in modern, technology-driven societies for their ability to create magnets with unique characteristics. These elements are utilized in a wide variety of consumer and industrial applications from smartphones and televisions to electric cars. Dura magnetics utilizes neodymium-iron-boron (NdFeB) magnets […]

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….

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…
