PURPOSE:To manufacture directly and inexpensively a fine silver alloy wire from a molten silver alloy by ejecting the molten silver alloy added with a prescribed ratio of Be from a fine hole or slit and solidifying the same in fluid. CONSTITUTION:An Ag-Be alloy added with 0.001-1wt% Be is heated and melted by a heater 2 in a graphite crucible 1 of a rotary underwater spinning device. Gaseous Ar is then introduced into the crucible 1 from above the crucible 1 in the direction X and the molten Ag-Be is ejected by the pressure thereof from the round hole in the bottom of the crucible 1 into the prescribed thickness of the rotating water formed on the inside peripheral surface of a rotary drum 3. A silver alloy wire 4 having an approximately circular sectional shape and, for example, 0.2mm. diameter is thus obtd. A silver alloy incorporated therein with <=30wt% >=1 kinds among Cu, Sn, Zn, In, Au, Bi, P, etc. may be used for the molten silver alloy. |
