A manufacturing method of a prosthetic alloy for a dental use is provided to mix copper, nickel, iron, palladium and aluminum in a high frequency furnace very efficiently to make a prosthetic alloy that can replace gold and platinum. In a manufacturing method: 70-80% of copper, 3-5% of nickel, 3-5% of iron, 4-5% of palladium, 5-7% of aluminum and 5-8% of other metal are melt; palladium, nickel and iron that are cut in proper sizes are stacked on a copper pipe according to the order of melting point, are heated and melted at 1,650 - 1,700 deg.C in a melting pot of high frequency, are molded through a mold in the shape of a plate or a tub; and are cut in a predetermined size to form a prosthetic alloy for a dental use to prevent the aluminum having a low melting point from being oxidized.
