Xionghai Permanent Magnets preparesits anisotropic powders by either casting an alloy melt into a mold, or strip casing. Strip Casting offers the advantage of better chemical stability. Subsequently, the ingot from the mold or the flakes from Strip Casting are pulverized to a uniform grain/particle size. The best method for obtaining the desired grain size is by HDDR. The HDDR [hydrogenation-decomposition-desorption-recombination] process yields a more homogenous particle size with a minimum of α-Fe, and Nd-rich phases. Anisotropic Nd-Fe-B, HDDR powders prepared from strip cast alloys are used for the HAST [Highly Accelerated Stress Test] grades of NdFeB Magnets, including N, H, SH, UH, EH, and AH grades.
