AI Technical Summary

Benefits of technology

This new type of metal wire used for electricity transmission or power distribution offers better performance compared to previous designs due to its high level of conductive properties (I AC S) that exceeds 6.9% IACSC). It also exhibits good mechanical characteristics such as tension force, bending stress, impact shock tolerance, etc., which makes them ideal materials for use in various applications like wires for communication systems.

Problems solved by technology

The technical problem addressed by us is finding better ways to replace traditional metals like copper while maintaining good electric conduction capabilities at reasonable cost levels compared to alternative options made from pure metal or plastic alternatives.

Embodiment 1

[0022] The melting and casting method steps of aluminum alloy conductor of the present invention are as follows:

[0023] 1. Ingredients

[0024] Dosing according to the following composition ratio range as the base point: Si, 0.03-0.15%; Cu, 0.01-0.25%; Zr, 0.02-0.45%; Fe, 0.3-0.9%; Mg, 0.001-0.012%; B, 0.001-0.015% %; rare earth elements, 0.03-0.20%; the balance is aluminum and unavoidable impurities, and the ingredients should not exceed this range.

[0025] 2. Melting

[0026] The smelting temperature of rare earth aluminum alloy is controlled within the range of 700-760°C. If the temperature is too high, the oxidation process of aluminum will be aggravated. If the temperature is too low, the molten aluminum will be in the form of porridge, making it difficult to separate the slag and impurities. The slag that has been floating on the liquid surface should be removed in time, because the structure of the aluminum oxide film formed on the liquid surface is very dense, whi...

[0064] Mg, 0.002%;

[0065] B, 0.002%;

[0066] Rare earth, 0.06%;

[0067] The balance is aluminum and unavoidable impurities.

[0068] After testing, its electrical conductivity is 60.4%IACS, its tensile strength is 122MPa, and its elongation at break is 15.6%.

Embodiment 3

[0070] According to the melting and casting method in embodiment 1, a kind of aluminum alloy conductor material comprises the following components by weight percent:

[0073] Zr, 0.15%;

[0074] Fe, 0.85%;

[0075] Mg, 0.006%;

[0076] B, 0.004%;

[0077] Rare earth, 0.04%;

[0078] The balance is aluminum and unavoidable impurities;

[0079] After testing, its electrical conductivity is 61.9%IACS, its tensile strength is 116MPa, and its elongation at break is 19%.
