NdFeB Magnet
With strictly quality control our products enjoy great popularity around the world.

Ketian magnet prepares its 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.

When you purchased magnets form Ketian magnet you get the following superb benefits:

Improved Corrosion Resistance:8
NdFeB Magnet

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:

Ketian magnet offers a number of coatings including: Nickel, Epoxy, Zinc, Tin, Phosphate, polypropylene etc.

Good Surface Tension and adhesion:
NdFeB Magnet

Adhesives require a properly prepared surface for bonding. Good wet-ability is one of the keys to good bonding. The shear strength for our Ni Plated magnets is greater than competitive magnets.
