Embodiment 1
[0014] The copper alloy used contains the following components in weight percentage: 0.5% Yb, 0.8% Nd, 5.0% Cr, 8.0% Zr, 0.10% Mg, 0.08% Ag, 0.001% Ni, 0.001% % Mn, 0.005% Ti, and unavoidable impurities, the balance being copper. First of all, electrolytic copper is used as the copper raw material, and various alloy elements are added to the melting equipment according to the ratio. The melting equipment is an intermediate frequency vacuum induction furnace. The alloy is in a molten state. The molten alloy was poured slowly at a centrifugal speed of 300 r / min at a pouring temperature of 1200° C., and argon gas was filled into the smelting equipment to 0.5 MPa during pouring to obtain an ingot. Then, after cooling the ingot to room temperature, heat it to 800°C for annealing, and keep it warm for 4 hours, then air-cool it, then heat the ingot that was air-cooled to 300°C to 550°C for tempering, and keep it warm for 2 hours, and finally again The normal temperature tensile str...

[0016] The copper alloy adopted contains the following components by weight: 0.8% Yb, 1.0% Nd, 4.0% Cr, 5.0% Zr, 0.30% Mg, 0.05% Ag, 0.005% Ni, 0.005% % Mn, 0.005% Ti, and unavoidable impurities, the balance being copper. First of all, electrolytic copper is used as the copper raw material, and various alloy elements are added to the smelting equipment according to the ratio. The smelting equipment is an intermediate frequency vacuum induction furnace. The alloy is in a molten state. The alloy in the molten state was poured slowly at a centrifugal speed of 350 r / min at a pouring temperature of 1200° C. During pouring, argon gas was filled into the smelting equipment to 0.5 MPa to obtain an ingot. Then, after cooling the ingot to room temperature, heat it to 850°C for annealing, and keep it warm for 3 hours, then air-cool it, then heat the ingot that was air-cooled to 300°C to 600°C for tempering, and keep it warm for 1 hour, and finally again The normal temperature tensile s...

[0018] The copper alloy used contains the following components in weight percentage: 1.0% Yb, 1.0% Nd, 3.0% Cr, 6.0% Zr, 0.20% Mg, 0.03% Ag, 0.001% Ni, 0.005% % Mn, 0.001% Ti, and unavoidable impurities, the balance being copper. Firstly, electrolytic copper is used as the copper raw material, and alloy elements are added to the smelting equipment according to the ratio.

The alloy in the molten state was poured slowly at a centrifugal speed of 350 r / min at a pouring temperature of 1200° C. During pouring, argon gas was filled into the smelting equipment to 0.5 MPa to obtain an ingot. Then, after the ingot was cooled to room temperature, it was heated to 850°C for annealing, and kept for 2 hours, then air-cooled, and the ingot that was air-cooled to 300°C was reheated to 500°C for tempering, and kept for 1 hour, and finally again The normal temperature tensile strengt...
