Understanding Grade Integrity in NdFeB Magnets: The Hidden Cost of “Stealing Performance”

In the world of sintered NdFeB (neodymium-iron-boron) magnets, performance is defined not only by magnetic strength but also by intrinsic coercivity (Hcj) — the key parameter that determines a magnet’s ability to resist demagnetization at elevated temperatures. According to international standards, different magnet grades are categorized based on their Hcj ranges. For instance: On paper, […]
