Powder manufacturing apparatus and method therefor

A method for manufacturing alloy comprising: allowing a consumable electrode consisting a single metal element to form a pair of electrodes which have the same element, to set plurality of the pair so that an electrode metal element of each of the plurality of the pair may be different from one another; generating arc between the electrodes in a non-oxidizing atmosphere, to allow the consumable electrodes to be melted at their top ends; and allowing molten drops produced by the melting to go down into a mold to form molten metal, and the molten metal to be cast into alloy consisting of two metal elements. Two pairs consisting of the consumable electrodes allow the two consumable electrodes to be set on an axis, with a predetermined distance between their top ends, on horizontal plane above the mold. The two pairs of the consumable electrodes are alternated by three pairs of the consumable electrodes when alloy consisting of three metal elements.
