Copper alloy wire

Abstract

The invention relates to a copper alloy wire. The copper alloy wire comprises, by weight, 94.7036% or higher of copper, 0.2% or higher of tin, 0.00038% or less of nickel, 0.000475% or less of ferrum, 0.00095% or less of antimony, 0.00019% or less of zinc, 0.0057% or less of oxygen, 0.000475% or less of manganese, 0.000475% or less of phosphorus, 0.0019% or less of bismuth, 0.000475% or less of arsenic, 0.000475% or less of gold and more than 5% of electroplating silver. The flexibility and the ductility of the copper alloy wire are improved.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a copper alloy wire. Background technique [0002] The wires used in cables are mainly annealed copper wires or twisted wires formed by twisting copper wires plated with tin. Recently, the requirements for the flexibility, ductility, and electrical conductivity of wires have become higher and higher, and existing wires have been unable to meet these requirements. Contents of the invention [0003] The object of the present invention is to provide a copper alloy wire with flexibility and ductility. [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a copper alloy wire, its material composition includes by weight percentage: copper ≥ 94.7036%, tin ≥ 0.2%, nickel ≤ 0.00038%, iron ≤ 0.000475%, antimony ≤ 0.00095%, zinc ≤0.00019%, oxygen ≤0.0057%, manganese ≤0.000475%, phosphorus ≤0.000475%, bismuth ≤0.0019%, arseni...
