High-electric-conductivity Ba and Re-contained aluminum alloy for copper-clad aluminum conductor and machining process thereof

Abstract

The invention discloses a high-electric-conductivity Ba and Re-contained aluminum alloy for a copper-clad aluminum conductor and a machining process thereof. The alloy comprises the following components in percentage by weight: 0.8-1.5 wt.% of Ba, 0.2-0.4 wt.% of Re, 0.2-0.3 wt.% of Zr, 0.5-0.8 wt.% of Zn, 0.1-0.2 wt.% of Pd, 0.5-0.8 wt.% of Te, and the balance of aluminum. The aluminum rhenium alloy achieves excellent mechanical performances and electric conductivity, which are not possessed by a traditional aluminum alloy for the copper-clad aluminum conductor. The alloy achieves wide purposes in the electric appliance manufacturing industry, the electric wire and cable 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 conducting 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 low density and can be pulled over longer distances, but its conductivity is worse than copper One piece. The conductivity of aluminum is second only to silver and copper. Although its conductivity is only 2 / 3 of copper, its density is only 1 / 3 of copper. Therefore, the quality of aluminum wire is only half that of copper wire for the same amount of electricity. [0003] Aluminum is not only inferior to copper in electrical conductivity, but also in strength and corrosion resistance. In the 1970s, due to lack of copper resources, it was promoted to replace copper wires with aluminum. However, shortcomings continued to be...

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.
