The Effects of Chemical Composition on Soft Magnetic Materials Behaviour

The main aim of the presented work was to study the effects of chemical composition on the magnetic properties (in terms of B-H characteristics) of an insulated iron powder compound with various addition of the aluminium alloy (0, 5 and 10 wt%). The magnetic properties of the powder were significantly influenced by density and "sintering" effects. The addition of aluminium alloy maintaining suitable values of coercive force, remanence and core losses; this makes the modified insulated iron powder compound a promising soft magnetic material in several applications.
