Example Embodiment
[0044] Example 1
[0045] Copper-nickel 19 metal wire consists of 18% Ni, 0.6% Mn, 1% Fe, 0.1% Al, 0.5% Si, 0.01% Sn, 0.01% B, 0.001% Re, and 79.779% Copper composition.
[0046] The copper-nickel 19 metal wire is prepared by the following method:
[0047] (1) Mix and smelt the raw materials, peel and forge the obtained ingot;
[0048] (2) After the forging blank is drawn to obtain a filament with a diameter of 4.0mm, it is drawn again to obtain a filament with a diameter of 1.0mm and then annealed. The filament is drawn again to obtain a filament with a diameter of 0.3mm and then annealed. After drawing a filament with a diameter of 0.15mm, annealed, and finally a filament with a diameter of 0.15mm is obtained.

[0049] Example 2
[0050] Copper-nickel 19 metal wire is composed of 20% Ni, 0.01% Mn, 0.1% Fe, 1% Al, 0.01% Si, 1% Sn, 0.5% B, 0.1% Re, and 77.28% Copper composition.
[0051] The copper-nickel 19 metal wire is prepared by the following method:
[0052] (1) Mix and smelt the raw materials, peel and forge the obtained ingot;
[0053] (2) After the forging blank is drawn to obtain a filament with a diameter of 8.0mm, it is drawn again to obtain a filament with a diameter of 6.0mm and then annealed. The drawing annealing is repeated 6 times to obtain a filament with a diameter of 0.05mm. .
