With strictly process control every single piece of our magnet is to your totally satisfactory

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:

 

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:

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.
