DA Technology Achieves World's Highest Maximum Energy Product for 'Mn-Bi Ferrite Magnet'

DA Technology announced on the 28th that it has succeeded in achieving the world's best magnetic properties of the 'Manganese-Bismuth (Mn-Bi)' alloy through new process development in collaboration with Corisen.

According to the Korea Institute of Materials Science, the Mn-Bi alloy powder and bulk recorded a world-class maximum energy product (BHmax) value of 14.4 MGOe. The theoretical maximum energy product value of Mn-Bi ferrite is approximately 16 to 17 MGOe, and DA Technology and Corisen achieved about 89% of the theoretical figure. Based on this result, they are conducting collaborative projects with domestic completed car manufacturers.

The maximum energy product (BHmax) indicates the strength (magnetism) of a permanent magnet and has the highest efficiency relative to energy density when operating at the maximum energy product. Fundamentally, Mn-Bi permanent magnets have superior high-temperature characteristics compared to existing Nd (Neodymium)-based magnets and general ferrites, making them suitable for high-speed rotation or high-temperature use.

DA Technology has secured upgraded Mn-Bi alloy powder manufacturing capabilities through new process development in addition to the unique properties of Mn-Bi ferrite, and it is expected to replace not only rare earth permanent magnets but also existing ferrites.

A company official stated, “Having confirmed the world's best level of Mn-Bi ferrite maximum energy product through new process development, based on this result, not only collaborative projects but also supply negotiations are expected to gain momentum,” adding, “Ferrites are currently expanding beyond electronics and home appliances into various industries such as automotive, military, and defense, and we plan to sequentially target fields where rapid application is possible.”
