Anotace textu normy ASTM A1070-16(2022) :

This specification covers technically important, commercially available, magnetically hard, cast and sintered permanent magnets known commonly as Alnico. Alnico magnets have approximate magnetic properties of residual magnetic induction from 0.52 T (5200 G) to 1.35 T (13500 G) and coercivity from 38 kA/m (475 Oe) to 175 kA/m (2200 Oe). Their specific magnetic hysteresis behavior (demagnetization curves) can be characterized using Test Method A977/A977M.
