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, […]
Two Main Approaches for Exporting Rare Earth Permanent Magnets from China
Currently, there are two main approaches for exporting rare earth permanent magnet materials from China: 1. Applying for a “Dual-Use Items” export license from the Ministry of Commerce2. Adopting a heavy-rare-earth-free manufacturing solution Below is a brief comparison of the two methods. 1. Applying for a “Dual-Use Items” Export License This is […]
Detailed Analysis of Challenges Faced by the Rare Earth Permanent Magnet Industry under Export Control Policies
I. Core Policy Restrictions These controls involve seven key rare earth elements: Samarium (Sm), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Lutetium (Lu), Scandium (Sc), and Yttrium (Y). The most stringent requirement is that the total content of these elements must not exceed 0.1%. Behind this seemingly simple number lies enormous implementation challenges. II. Three Major […]
