Abstract

PURPOSE: To obtain a high-strength material less in defection by reducing segregation, by redissolving an once vacuum-dissolved material of an alloy of low-melting point metal and copper.
CONSTITUTION: In a method of dissolving and casting a copper alloy that contains 0.1W2wt% low-melting point metal which is dissolved in copper by ≥5wt% in liquid phase, but by only ≤0.1wt% in solid phase and never produce an intermetal compound with copper, copper in a crucible in a vacuum tank is dissolved by being heated for degassing and argon gas is supplied up to prescribed pressure; and then argon gas is excluded and bismuth is added. After the bismuth is sufficiently dissolved in molten copper, the copper is poured into a mold at a prescribed temperature. Next, a Cu-Bi alloy obtained by the 1st dissolving casting is poured in the crucible in the vacuum tank, which is evacuated and argon gas is supplied. The Cu-Bi alloy in the crucible is dissolved by being heated and casted into the mold at a prescribed temperature. The distribution of the low-melting point added metal becomes more even than that of a material dissolved once and metal structure having the added metal distributed at a high level can be obtained.
