Embodiment 1
[0040] A high-performance CuNiSiTiBMg-based elastic copper alloy of the present invention, in weight percent, the high-performance CuNiSiTiBMg-based elastic copper alloy contains the following components: Ni 8.0%, Si 2.0%, Ti 1.0%, B0.1%, Mg 0.2%, the rest is Cu and unavoidable impurities.
[0041] The preparation method of the high-performance CuNiSiTiBMg system elastic copper alloy of the present embodiment comprises the following steps:
[0042] (1) Prepare materials according to the weight percentage of the constituent elements in the high-performance CuNiSiTiBMg-based elastic copper alloy. Put electrolytic copper, electrolytic nickel, electrolytic silicon and electrolytic titanium into a heating furnace for melting at a melting temperature of 1250 ° C. After they are completely melted , lower the temperature to 1250°C, then add pure magnesium, and form an alloy melt after melting;
[0043] (2) The alloy melt is continuously cast into a slab on a continuous casting machin...
