Abstract
The invention provides an aluminum alloy conductor and a preparation method thereof, wherein the aluminum alloy conductor includes the following elements in mass percentage: magnesium: 0.50% to 0.70%, silicon: 0.35% to 0.60%, copper: 0.05% to 0.15%, iron : 0.05% to 0.20%, zirconium: 0.01% to 0.15%, yttrium: 0.03% to 0.15%, titanium: 0.003% to 0.015%, boron: 0.03% to 0.05%, manganese: 0.001% to 0.015%, unavoidable impurities : The total content is <0.15%, and the balance is aluminum. The present invention can solve the problem that the electrical conductivity of the aluminum alloy is greatly reduced due to the addition of alloy elements to improve the strength of the existing conductive aluminum alloy in the prior art.
Description
Aluminum alloy conductor and preparation method thereof technical field The present invention relates to the technical field of conductive materials, more particularly, to a kind of aluminum alloy conductor and preparation method thereof. Background technique At present, in the field of electric power industry, aluminum alloy conductors have the advantages of low price, light weight, high strength, and good workability. With the advantages of good performance, excellent electrical conductivity and corrosion resistance, "replacing copper with aluminum" has become the main development trend. Aluminum alloy conductors have been It has been applied to the fields of wire and cable, cross rail profiles, electrodes, etc., and has achieved good economic and social benefits. With the development of industry, higher requirements are put forward to aluminum alloys, and the indicators such as the strength and plasticity of aluminum alloys have not been The law meets the require...
