ASTM A1101-23

Annotation of standard text ASTM A1101-23 :

This specification covers technically important, commercially available, magnetically hard sintered and fully dense neodymium iron boron (Nd2Fe14B, NdFeB, or “Neo”) permanent magnets. These materials are available in a wide range of compositions with a commensurately large range of magnetic properties. Neodymium iron boron magnets have approximate magnetic properties of residual magnetic induction from 1.08 T (10 800 G) up to 1.5 T (15 000 G) and intrinsic coercive field strength of 875 kA/m (11 000 Oe) to above 2785 kA/m (35 000 Oe). Special grades and isotropic (un-aligned) magnets can have properties outside these ranges.
