PURPOSE:To simply manufacture a permanent magnet having a ready manufacture and excellent magnet characteristics by mixing Fe, Pd and Ag in a specific atomic ratio. CONSTITUTION:Raw materials are so mixed that approx. 19.5-41% of Pd, approx. 0.1-27.5% of Ag and approx. 0.5% or less of impurity and Fe of the residue are contained, the mixture is molten in an air, an inert gas or in vacuum, the mixture is then sufficiently stirred, and a molten alloy having uniform composition is thus produced. The molten metal thus mixed is poured into a casting mold having an adequate shape and size or is intaken into a quartz tube as a sound cast. The cast is then forged, drawn at room temperature, and is formed in an objective shape. Subsequently, the alloy is suitably solid solution treated at a temperature range of approx. 600-1,200 deg.C in gamma phase for suitable time, is then cooled and is eventually tempered at a temperature range of approx. 350-550 deg.C. Thus, there can be simply produced an alloy having a ready manufacture and large produce of coercive force and maximum energy for a magnet.
