Problems solved by technology

[0005] However, power cables with a voltage level of 600V ~ 35kV only account for a small part of the total amount of wires and cables. For wires and cables with other voltage levels and occasions, they still cannot meet a large number of needs, such as cables below 600V and various electrical appliances and equipment. et...

Abstract

The invention provides a super-soft aluminum alloy conductor and a preparation method thereof. The aluminum alloy conductor comprises the following materials in percentage by weight: 0.3 to 1.5 percent of Fe, 0.001 to 0.3 percent of Be, 0.005 to 0.6 percent of Cu, 0.1 to 1.5 percent of rare earth, less than or equal to 0.08 percent of Si, less than or equal to 0.15 percent of total inevitable impurities, and the balance of aluminum. The aluminum alloy is drawn into an aluminum alloy wire by melting, continuous casting and continuous rolling, and the aluminum alloy wire is put into an annealing furnace and annealed for 20 to 40 hours at the temperature of between 380 and 420 DEG C to form the aluminum alloy conductor, wherein the annealing is performed in a sealed heat insulation device under the protection of nitrogen. The aluminum alloy has extremely good toughness and elongation performance, the coefficient of elongation reaches or exceeds 35 percent and even can reach 40 percent, and the electric conductivity can reach 60 percent IACS.

Description

technical field [0001] The invention belongs to the field of nonferrous metal materials, and in particular relates to an extra-soft aluminum alloy conductor and a preparation method thereof. Background technique [0002] According to the statistics of China Nonferrous Metals Industry Association, as of 2009, China's reserves of copper resources were about 30 million tons, accounting for about 5% of the world's total reserves. China is a big country that consumes copper, with an annual copper consumption of about 6 million tons, of which copper used in wires and cables accounts for about 65% of the national copper consumption, accounting for a large proportion. If it does not rely on imports, China's copper resources can be used up to 5 year time. China's domestic copper concentrate supply is less than 30%, and more than 70% needs to rely on imports. [0003] Because copper has excellent electrical conductivity and mechanical properties, it is the first choice for wire and ...
