Abstract

The invention relates to an energy-saving high-elongation soft aluminum alloy wire and a preparation method thereof. The aluminum alloy wire is mainly composed of the following components in percentage by weight: 0.05-0.40% of Cu, 0.10-0.40% of Zr, 0.25-1.00% of Fe, 0.01-0.22% of Mg, 0.001-0.15% of Si, 0.05-0.15% of Y, 0.05-0.10% of Sc, and the balance of Al and other inevitable impurity elements. The amount of each element in the other inevitable impurity elements does not exceed 0.03%, and the total amount of all the other inevitable impurity elements does not exceed 0.15%. The aluminum alloy wire has the advantages of favorable creep resistance, high elongation percentage, favorable bending property and the like, is easy for machine-shaping, and can ensure the stability of the electrical connection.

Description

technical field [0001] The invention relates to an aluminum alloy wire, in particular to an energy-saving and high-stretch soft aluminum alloy wire and a preparation method thereof. Background technique [0002] At present, most of the electrical conductive materials used for power transmission are made of copper, but due to the shortage of domestic copper resources, about 70% of the copper materials need to be imported, and with the rising international copper price, the investment cost of conductive materials is increasing. The higher the value, the greater the consumption of copper resources. my country is a country rich in aluminum and poor in copper. There are a lot of aluminum resources in the country but they are not fully utilized, which is a great waste. Now the country advocates building a conservation-oriented society, and the industry is also encouraging the use of "aluminum saving copper". [0003] Due to the low electrical conductivity, low yield strength, la...
