Neodymium permanent magnets
(Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals. These magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.

Xionghai magnet 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/cm2.
High Maximum Working Temperature:
Our AH series of NdFeB magnets have working temperatures up to 240°C.
Excellent Corrosion Resistance:
