The national standard GB/T 43750-2024, Test Method of Magnetic Properties of Isotropic Rare-earth Permanent Magnetic Powder, was jointly formulated by multiple enterprises and research institutions and implemented on October 1, 2024. Hangzhou Chase Technology, one of the key participants, significantly contributed to its development. The standard covers methods for measuring remanence, magnetic induction coercivity, intrinsic coercivity, and maximum energy product. Its formulation is crucial for standardizing measurements, enhancing product quality, and raising technical standards. Hangzhou Chase’s involvement reflects its strength in technology research and commitment to the magnetic materials industry. The standard’s publication will provide unified specifications and quality standards, contributing to the sustained and healthy development of China’s magnetic materials industry.
