Abstract
PURPOSE:To obtain a favorable degree of sintering and to contrive to enhance magnetic characteristic of a magnetic material by a method wherein a mother alloy powder of Fe-Al-Si to be mixed with Fe powder is made to contain one kind or more of elements of the platinum group and one kind or more of Ca, Mg. CONSTITUTION:The mother alloy powder of Fe-Al-Si to be mixed with Fe powder is made to contain one kind or more of the elements of the platinum group and one kind or more of Ca, Mg, and the material is made to have the composition of 3-8wt% of Al, 3-12wt% of Si, 0.01-2.5wt% in gross weight of the elements of the platinum group, 0.01-0.3wt% in gross weight of one kind or more of Ca and Mg, and making the rest of Fe as the main component. Accordingly the degree of sintering thereof can be enhanced remarkably, and the magnetic material having high effective permeability and high corrosion resistance can be obtained.
