IEC Standard for Rare earth-iron-boron (REFeB) Magnets

The International Electrotechnical Commission (IEC) published the standard IEC 60404-8-1:2015 for magnetically hard materials (permanent magnets). In this standard, the part of Rare earth-iron-boron (REFeB) magnets’ magnetic properties and densities is shown in the table below. In the REFeB magnets, the RE element is mainly neodymium (Nd), and the manufacturing method is a powder sintering process, so REFeB magnets are also known as sintered NdFeB magnets. China supplies most of the sintered NdFeB magnets in the global market, for those… Read More
