Embodiment 1
[0044] This embodiment provides a nickel-copper alloy, its composition weight percent is: Cu: 30.5%, Al: 2.88%, Ti: 0.47%, Mn: 1.18%, Si: 0.35%, C: 0.06%, S: 0.002 %; the balance is Ni.
[0045] The production technology of this nickel-copper alloy comprises the following steps:
[0046] Get the raw material, the weight percentage of the raw material is composed of: 31% Cu, 3% electrolytic aluminum, 0.5% pure titanium, 1.2% electrolytic manganese, 0.37% pure silicon, 0.07% carbon powder, and the remaining electrolytic nickel ;The raw material is smelted in a vacuum intermediate frequency melting furnace at 1550-1650°C to produce a melt, and a small amount of magnesium copper is added as a degasser during the smelting process;
[0047] The melt is refined at 1600°C for 45 minutes;
[0048] Stand still at 1550°C for 30 minutes after refining;
[0049] After cooling down to 1520°C, pour it into a cast iron mold and cool to room temperature to obtain an ingot;
