8/31/2023 0 Comments Samarium cobaltThe technology to produce a stronger SmCo magnet was funded and developed by the CMI, a public/private partnership that brings together experts from U.S. ![]() We look forward to a fruitful collaboration with Ames." "There is a real niche here in the magnet market, with great opportunities," said Melania Jasinski, Director of Engineering for the Electron Energy Corporation (EEC), which is a major domestic producer of SmCo magnets, "So the company is highly interested in optimizing our production. "The structural fragility of these magnets creates a lot of waste in the manufacturing process, and limits their applications in many technologies where they would otherwise be a good choice," said Baozhi Cui, a scientist at the Critical Materials Institute (CMI) who leads a team that researches ways to make rare earth permanent magnets more powerful, efficient, mechanically robust, and cost-effective. The process by which they are made, pressing metal powder into a solid mass, called sintering, makes them susceptible to chipping and fractures during the manufacturing process, as well as failure in any environment where there is too much vibration or mechanical shock. The one downside to SmCo magnets? They are brittle. ![]() That high magnetic power density and excellent temperature stability has made SmCo magnets the first choice for many uses, including military, spacecraft, aerospace, and marine applications. They are extremely resistant to demagnetization, and able to withstand high heat and corrosion. Since their development in the 1960s, SmCo magnets have been a workhorse in modern technology, second only in strength to neodymium magnets. Ames Laboratory will partner with Electron Energy Corporation to improve a mainstay of magnet technology- the samarium cobalt (SmCo) magnet.
