Neodymium iron boron magnets, written NdFeB, are the sintered neodymium magnets at the centre of this site. The company's product pages describe the sintered neodymium magnet as the strongest magnetic material commercially available today, and give its alloy as neodymium, iron and boron, Nd2Fe14B. That sentence is a company product-page statement, and this site keeps it in that form rather than upgrading it into an independent laboratory finding. What a buyer can verify here is narrower and more useful: which shapes are published, what size range each shape carries, what tolerances apply to that shape, and which magnetization directions are listed for it.

What NdFeB means on this site
NdFeB is the short chemical shorthand for neodymium, iron and boron. On this site it always refers to the sintered neodymium magnet line published by the company, not to bonded material, ferrite, alnico or samarium cobalt, none of which have a published shape range here. Keeping that boundary matters, because buyers sometimes arrive with a magnet word from another material family and expect the same size table to apply. It does not. If your drawing calls for a material outside sintered NdFeB, say so in the inquiry rather than assuming a substitution, and the specification review can confirm whether the published range covers it.
The six shape families carry the whole published range: disc and cylinder, block and plate, ring and tube, arc and segment, sphere, and countersunk. Custom shapes sit outside the six as a made-to-order route. Magnetic assemblies are a separate category list of eight names, published at navigation level only. No assembly on this site carries a size, pull-force, coating or base-material parameter, because none was verified shape by shape.
Reading the shared grade temperature table
Every shape page on the company's site carries the same grade maximum working temperature table, and this site reproduces it as a shared table. The series run from N35–N52 at 80°C through the M, H, SH and UH series to the EH series at 200°C. The table answers one question only: the listed maximum working temperature for a grade series. It does not, by itself, select a grade for an application, and grade names must not be read as performance promises beyond that temperature figure. A buyer who needs a grade decision should state the operating temperature, the shape, and the magnetization direction together, so the review can be made against all three at once.
What to confirm before ordering
Four items should be in every inquiry: the shape family, the dimensions within that family's published range, the grade temperature series, and the magnetization direction exactly as listed for that shape. Add coating requirements as a question, not as an assumed type, because coating type names were not transcribed from the company's illustration. Add the operating environment where temperature, humidity or mechanical fixing matters. Please confirm minimum order quantity and lead time before ordering. Warranty terms are unavailable on the published pages — please confirm warranty terms before ordering.
