Problems solved by technology

This method has the disadvantages of high cost to varying degrees, flux inclusions in castings, and complicated equipment.
Therefore, the research, development and application of aluminum-barium alloys are limited.
Therefore, in the industrial and national defense fields that are in urgent need of large-scale use of aluminum-barium alloys, there has always been a current situation that needs to be overcome, such as low output, cumbersome processes, and high costs.

Abstract

The invention discloses a high-heat-conductivity Ba and Se including aluminum alloy for a copper-clad aluminium conductor and a processing process of the high-heat-conductivity Ba and Se including aluminum alloy. The alloy is prepared from, by weight percent, 0.5-1.2 wt.% of Ba, 0.2-0.6 wt.% of Ge, 0.2-0.4 wt.% of Hf, 0.2-0.5 wt.% of Ru, 0.1-0.3 wt.% of Os, 0.4-0.8 wt.% of Se and the balance aluminum. The aluminum-barium alloy has the excellent mechanical property and heat conducting property failing to achieve on a traditional copper-clad aluminum conductor and has wide purposes in the electric appliance manufacturing industry, the electric wire industry and the radio industry.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum-barium alloy. Background technique [0002] Both copper and aluminum are good materials for wires, but copper is not suitable for long-distance transmission lines because of its high density and cannot be pulled over long distances; aluminum has a low density and can be pulled over long distances, but its conductivity is worse than copper a cut. The conductivity of aluminum is second only to silver and copper. Although its conductivity is only 2 / 3 of that of copper, its density is only 1 / 3 of that of copper. Therefore, the quality of aluminum wire is only half of that of copper wire when transporting the same amount of electricity. [0003] Not only is aluminum less conductive than copper, it is also much weaker in strength and corrosion resistance than copper. In the 1970s, due to the lack of copper resources, the use of aluminum instead of copper wires was promoted...
