This specification applies to technically important, commercially available, magnetically hard sintered (fully dense) permanent magnets commonly known as samarium cobalt (SmCo). SmCo permanent magnets are available in two general composition families abbreviated “SmCo 1:5” and “SmCo 2:17.” These materials have approximate magnetic properties of residual magnetic induction from 0.78 T (7800 G) to 1.18 T (11 800 G) and intrinsic coercivity typically greater than 800 kA/m (10 000 Oe). Special grades and isotropic (un-aligned) magnets can have properties outside these ranges. Specific magnetic hysteresis behavior (demagnetization curve) can be characterized using Test Method A977/A977M.
