Scientists of Minnesota are working on a new technology with iron and nitrogen replacement of rare earth to create high-performance magnets
Scientists at the university of Minnesota are working on a new technology, with iron and nitrogen replacement of rare earth to create high-performance magnets.
The university also set up a named Niron Magnetics company to make new technology commercialization. With the first batch of samples will be built next year, to full production will be in a year later.
At present, the productions of high performance magnets need to add rare earth elements, such as neodymium and dysprosium anti high temperature demagnetization. Scientists are designing magnets for better environmental protection, not like production lead to serious pollution in parts of China.
Rare earth magnets much more expensive compared to other common varieties. Considering the availability of iron and nitrogen, the cost of the new type of magnetic material is far below the cost of rare earths. However, they will need different production process, the industry needs time to optimize, make this kind of new type of magnetic material cost lower than that of rare earth magnets.
This project has attracted $4 million in funding from the DOE.
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
