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.

Why the alloy matters to a buyer
The alloy designation Nd2Fe14B tells a buyer which material family the magnet belongs to, and it prevents confusion with other magnet families that share the word magnet but not the material. Ferrite, alnico and samarium cobalt magnets are not part of the published range on this site, and their size tables, if any, are not reproduced here. A drawing that specifies only the word magnet, without material, shape and grade series, is not yet a complete specification. The inquiry form on this site therefore asks for shape, dimensions, grade series and magnetization direction as separate fields.
The company's sintered page also carries demagnetization curve charts for several grades. Those charts are mentioned here only as charts: their curve values were not transcribed item by item, so no curve number is quoted in this site's text, and no grade performance claim is derived from a curve. Buyers who need curve data should ask for the chart for the specific grade series under discussion.
