Xionghai 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.
Improved Corrosion Resistance:
The HAST protocol used on our
neodymium iron boron magnets can qualitatively reflect the service life of the magnet. This test exposes the magnet to 130°C, 95% RH, at 2 ATM for more than one day. The magnet is massed before and after the test. Our magnets measure a weight loss of less than 5 mg/cm
2.
High Maximum Working Temperature:
Our AH series of NdFeB magnets have working temperatures up to 240°C.
