Abstract

The invention discloses an anti-corrosion tensile-resistance cupronickel wire. The cupronickel wire is prepared from, by weight, 11-16 parts of Ni, 1-5 parts of Mn, 2-7 parts of Fe, 2-5 parts of Al, 1-6 parts of Zn, 1.2-1.8 parts of Sm, 0.4-0.7 part of La, 0.05-0.15 part of Pm, 0.10-0.38 part of Nd, 2-4 parts of Si, 3-5 parts of Sn, 2-6 parts of B and 1-5 parts of Re. According to the anti-corrosion tensile-resistance cupronickel wire, cupronickel is obtained by means of Ni, Mn, Fe, Al, Zn, Sm, La, Pm, Nd, Si, Sn, B and Re, and the cupronickel wire is excellent in corrosion resistance and excellent in all mechanical performance parameters such as tensile strength and elongation.

Description

technical field [0001] The invention relates to the field of copper wire processing, in particular to a corrosion-resistant and tensile-resistant white copper wire. Background technique [0002] Copper-nickel alloy, also known as white copper, is a copper-based alloy with nickel as the main additive element. The position of copper and nickel in the periodic table of elements is close, the atomic radius is very little difference, both are face-centered cubic lattice, so the two can dissolve each other infinitely, 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. The white copper wire currently on the market has comprehensive mechanical properties, corrosion resistance, and is easy to cut, but its various properties still cannot meet the existing needs. Contents of the invention [0003] In order to solve the above problems, the ...
