Block Magnets with Nickel-Copper-Nickel Plated,super strong,high quality magnet N35-N52---AH.
Can be Magnetized thru length ,width or thick

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.

Bigest block NdFeB magnets is one regular shape of Rare earth magnets and perment magnets.
It is always manufactured via Cutting and grinding etc .Block magnets or Rectangle magnets have the following important factors such as, Length,Width, Thicknes, Round Edge etc.

Our neodymium block magnets are mainly used in MRI equipment, liner motor, wind turbine and magnetic separator.

With our advanced equipment like hydrogen decrepition frunance and continuous sintering furnace, we can mass produce high grade like N52, 48H, 45SH, 40UH ,33AHetc.

Also with our experience in material preparation and machining, we can produce very big block, such as 8" length and 4" width.
Applications: sensors, motors, rotors, wind turbine,wind generators, loudspeakers, magnetic hooks, filters automobiles, Toys, micro-special electric machinery, audio equipments, electronic industry, auto industry, magnetic transmission gears and magnet therapy equipment, sorption, ads, teaching tools and other office automation, magnet toys, aero generators, magnetic toys, magnetic separators, magnetic bracelets, magnetic necklaces, copiers, synchrotrons, radiation sources, free electron lasers, agriculture, detection earthquake, and so on.
We are also expert for packaging and transporting the high energy big block neo magnets.

Our plating options include: nickel+copper+nickel, black epoxy and environmental Zinc coating.
