<p>The switching magnet composed of Si contg. Fe is produced by powder metallurgy and has a high mech. strength, low hysteresis losses, and high electrical resistance. These properties are obtained by limiting the particle size of the Si contg. Fe powder to 400 micron, the Si content between 2.5-3.6% pref. 3%. The density of the compacted body is between 6.2-6.8 pref. 6.5.</p> |
