Abstract

The invention relates to the field of copper-nickel alloy, in particular to a copper-nickel 19 metal wire and a preparation method thereof. The copper-nickel 19 metal wire comprises 18 to 20% of Ni, 0.01 to 0.6% Mn, 0.1 to 1% of Fe, 0.1 to 1% of Al, 0.01 to 0.5% of Si, 0.01 to 1% of Sn, 0.01 to 0.5% of B, 0.001 to 0.1% Re, and the balance being copper. The preparation method of the copper-nickel 19 metal wire comprises the following steps of: carrying out combined smelting according to a formula, recipe, peeling the obtained ingot, and forging; and drawing the forged blank, repeatedly drawing and annealing at least two times until the copper-nickel 19 metal wire with the required specification is obtained. The copper-nickel 19 metal wire prepared by the method has excellent corrosion resistance, high tensile strength and elongation, and has resistivity of about 0.25 omega . mm2 / m.

Description

technical field [0001] The invention relates to the field of copper-nickel alloys, in particular, the invention relates to a copper-nickel 19 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:...
