Abstract

The invention discloses a method for machining high-toughness anti-oxidation copper-based ultrafine wires. The method includes the following steps that S1, 0.1 wt%-0.5 wt% of Ag, 0.1 wt%-0.5wt% of Mg, 0.03 wt%-0.08 wt% of Pd, 0.01wt%-0.03wt% of Nb, 0.05 wt%-0.1 wt% of B, 0.08 wt%-0.016 wt% of rare earth and the balance Cu are subjected to vacuum smelting; S2, a copper bar blank is obtained through up-drawing, continuous extrusion is conducted, and copper wires are obtained after drawing; S3, the copper wires are subjected to process annealing, mixed gas of nitrogen and hydrogen is introduced, and an anti-oxidation solution is added dropwise; and S4, the cooper wires are dried and then drawn, process annealing is conducted, the mixed gas of nitrogen and hydrogen is introduced, and the copper-based ultrafine wires are obtained. According to the method for machining the high-toughness anti-oxidation copper-based ultrafine wires, the machined ultrafine wires have the high conductivity, and the requirements for oxidation resistance and plasticity of the wires can be met in actual engineering.

Description

technical field [0001] The invention relates to the technical field of copper material processing, in particular to a processing method of a high-toughness and oxidation-resistant copper-based ultra-fine wire material. Background technique [0002] Copper-based ultra-fine wire is widely used in electro-acoustic equipment, micro-relays, electronic transformers, micro-motors, IC cards and other electronic components and electronic leads. It is a new energy-saving and environmentally friendly material. At present, the domestic microfilament industry is mainly dominated by foreign manufacturers, and the core technology of production is also mainly mastered by foreign manufacturers. The domestic production capacity is far from meeting the demand, especially in the field of high-end microfilament (wire diameter below Ф0.05mm), product Mainly imported from Germany, Japan, South Korea and other manufacturers. [0003] This type of ultra-fine wire generally requires high electrical ...
