Embodiment 1
[0044] The copper-nickel 34 metal wire in this embodiment is composed of 33% Ni, 0.6% Mn, 0.01% Fe, 0.01% Ti, 0.01% B, 0.05% Re and 66.32% copper.
[0045] Copper Nickel 34 wire was prepared by:
[0046] (1) Mix and melt the raw materials, peel and forge the obtained ingot;
[0047] (2) After drawing the forged billet to obtain a filament with a diameter of 4.0mm, draw it again to obtain a filament with a diameter of 1.0mm, then anneal it, draw it again to obtain a filament with a diameter of 0.3mm, anneal it, and then draw it again The filaments with a diameter of 0.15 mm are pulled out and then annealed to finally obtain filaments with a diameter of 0.15 mm.
Embodiment 2
[0049] Copper Nickel 34 wire consists of 35% Ni, 0.05% Mn, 0.5% Fe, 0.3% Ti, 0.1% B, 0.001% Re, 0.3% Si, and 63.749% Copper.
[0050] Copper Nickel 34 wire was prepared by:
[0051] (1) Mix and melt the raw materials, peel and forge the obtained ingot;
[0052] (2) After drawing the forged billet to obtain a filament with a diameter of 8.0mm, draw it again to obtain a filament with a diameter of 6.0mm, then anneal, repeat drawing and annealing 6 times, and finally obtain a filament with a diameter of 0.05mm .

Abstract
The invention relates to a relates to the field of copper-nickel alloy, and in particular relates to a copper-nickel 34 metal wire and a preparation method thereof. The copper-nickel 34 wire comprises, by weight, 33-35% of Ni, 0.05-0.6% of Mn, 0.01-0.5% of Fe, 0.01-0.3% of Ti, 0.01-0.1% of B, 0.001-0.05% of Re, and the balance of copper. The preparation method of the copper-nickel 34 metal wire comprises the following steps: conducting mixed melting according to the formula; peeling the obtained ingot and forging; drawing the forged blank; and repeating drawing and annealing for at least 2 times, until the copper-nickel 34 metal wire with desired specifications is obtained. The copper-nickel 34 metal wire prepared by the method of the invention has low resistance temperature coefficient, excellent corrosion resistance, good welding performance and processing performance, high tensile strength and elongation rate, and resistivity about 0.40 ohm.mm<2> / m.
Description
technical field [0001] The invention relates to the field of copper-nickel alloys, in particular, the invention relates to a copper-nickel 34 metal wire and a preparation method thereof. Background technique [0002] Copper-nickel alloy, also known as white copper, is a copper-based alloy with nickel as the main additive element. The positions of copper and nickel in the periodic table of elements are close, the atomic radius is very little difference, both are face-centered cubic lattices, so the two can dissolve each other infinitely, and the alloy prepared in any proportion is a single solid solution organization, containing other elements Most of the complex copper-nickel alloys are also a single solid solution organization. [0003] Studies have shown that after adding nickel, the plasticity of copper does not decrease much, but the strength increases significantly. In other words, due to the addition of nickel, nickel-nickel has a series of excellent characteristics:...
