Hydrogen decrepitation is a crucial, energy-efficient process for manufacturing Neodymium magnets, using hydrogen to break down sintered alloy ingots into fine powder by targeting grain boundaries, avoiding intensive mechanical crushing. It can improve production efficiency by 25% and enable sustainable, […]
Magnetic technology looms large in two recent developments at Austrian international technology group Andritz. One involves a major expansion to its production of turbo generators, the other is acquisition of a majority stake in induction heating specialist company Sanzheng in China whose equipment is used particularly in the production of electrical steel. […]
Noveon Magnetics, a manufacturer of sintered NdFeB rare earth, has recently secured several supply and manufacturing agreements in Asia, Europe and Australia. Beginning in November, 2025, Noveon Magnetics signed a memorandum of understanding with Kangwon […]
Early next year, Seong-An Co., Ltd. of the Republic of Korea, traditionally a textile company, is expected to begin, or advance closer to beginning, its new phase as a sizeable manufacturer of magnets as well […]
Spurred by the global growh of automakers Hyundai and Kia, and now riding alongside Korean steel maker Posco International, Star Group of Korea is rising in prominence as a leading magnet manufacturer in Asia – […]
Mkango Resources is paying up with the help of a new partner up to acquire full control of pioneering British magnet recycler HyProMag. The companies plan to build a plant in the U.S. next, rolling out further HyProMag’s technology for processing of magnet scrap using hydrogen, developed at the University of Birmingham. First production using the process is targeted for the UK this year, Germany in 2024 and the U.S. to follow as the Vancouver-based minerals company continues to pursue development of its Songwe Hill rare earths property in Africa. […]
This White Paper from Arnold Magnetics describes the magnetization losses that are possible in SmCo and NdFeB permanent magnet materials. Reversible losses are first discussed followed by irreversible losses, which can be caused by temperature, external fields or radiation. Losses over time by magnetic viscosity are also discussed. Finally, permanent losses caused by corrosion, hydrogen, high temperatures and radiation are considered.
