Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material.
NdFeB is the most advanced commercialized permanent magnet material available today.
This material has similar properties as the samarium cobalt except that it is more easily oxidized
and generally doesn't have the same temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and are
mechanically stronger than samarium cobalt magents. NdFeB material is more costly by weight than
ceramic or alnico but produces the highest amount of flux per unit of volume or mass amking it very economical for many applicantions. Their high energy products lend themselves to comnpact designs
that result in innovative applications and lower manufacturing costs.
Unprotected NdFeB magnets are subject to corronsion. Surface treatments has ben developed that
allow them to be used in most applications. These treatments include copper, silver,, gold, nickel,
zinc and tin plating and epoxy resin coating.
Beneficial characteristics of NdFeB magnets include their very high energy product, very high
coercive force, and moderate temperature stability. Drawbacks include lower mechanical strength,
and low corrosion resistance when not properly coated or plated.
Magnetic Grades and Temperature:
The Grade of a magent directly refers to the Maximum Energy Product of the material that composes the magnet. It in no way refers to the physical properties of the magnet. Grade is generally used to describe
how "strong" a permanent magnet material is. The energy products is specified in the unites Gauss Oersted.
One MGOe is 1,000,000 Gauss Obersted. A grade forty (N40) would have a Maximum Energy Product of 40 MGOe.The higher the grade the "stronger" the magnet.
Magnetic materials have a wide range of working temperatures. The following chart the various materials and their maximum working temperature. NdFeB material

Description of the Disc Magnet
Neodymium magnet, the third generation of the rare-earth permanent magnet, is the most powerful and advanced permanent magnet today. The disc Magnet is one type of the neodymium. ... made of the neodymium, iron, and bonded magnetic alloy blend.
The disc magnet is plated with Nickel-Cooper-Nickel coating for a shiny corrosion-resistant finish. The North and South poles are on both flat side of the magnet since magnetizing direction is Axial Magnetizing. The magnet is powerful and can be used to help stuff to stick into the iron surface.
Tolerance:
For each magnet, there has a tolerance to produce, as follow:
+/- 0.05 mm for the small dimension;
+/- 0.1 mm for the common specification;
+/- 0.15mm for the big blocks.
Magnetic testing
As the third generation "Magnetic King", the disc neodymium magnet has its powerful pulling force.
Magnetizing Direction
The normal magnetizing method of the disc neodymium magnet: Axial and Radial.
With the Axial magnetizing, the magnetic spread over both flat side; with the Radial magnetizing, the magnetic spread over the surround.
Due to this product is a customizable product, so pls send us the specific size, the same as the picture, thanks!
Coating:
There have many plating options of the disc neodymium magnet, besides the Nickel coating, there also have Zinc, Gold, Black Epoxy, White Epoxy and so on.
The Black Epoxy and White Epoxy will be more durable.
Standard Bulk Packing
The common method of the packing for disc neodymium magnet:
Pieces packed into the little white paper box, then 8 boxes packed into the High-quality Corrugated carton box with anti-magnetic.
