Neodymium Block Magnets are a kind of NdFeB magnet. Since Neodymium Block Magnets are much stronger than other magnets, using Neodymium Block Magnets can build much more powerful motors and generators than ever.
The N40UH magnet has excellent temperature resistance, the highest working temperature can reach 180 ℃.

Block Neodymium Magnet Advantages
The most powerful permanent magnet offers a great return for cost &performance, have the highest field/ surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes.
2.World's most precise tolerance
The tolerances of magnets can be controlled within ±0.05mm or even more, if you have a special requirement for tolerance, please feel free to let us know.
3.Coating / Plating
Options: Nickel, Zinc (Zn) , Epoxy, Rubber, Gold, Silver, etc.
4.Magnetic Direction: Axial
Block magnets are defined by three dimensions: Length, Width and Thickness.
Usually magnetized through the length, width, or thickness of the magnet.
