Abstract

The invention discloses Ba-Pt-Cr aluminum alloy applied to a corrosion-resistant copper-clad aluminum wire and a machining process of the Ba-Pt-Cr aluminum alloy. The Ba-Pt-Cr aluminum alloy comprisesthe following components in percentage by weight: 0.5-0.8 wt% of Ba, 0.2-0.4 wt% of Pt, 0.5-0.6 wt% of Cr, 0.2-0.4 wt% of Sn, 0.8-1.2 wt% of Y, 0.1-0.3 wt% of Th and the balance of aluminum. The aluminum-barium alloy has excellent mechanical properties and corrosion resistance which the traditional aluminum alloy applied to the copper-clad aluminum wire does not have. The Ba-Pt-Cr aluminum alloyis widely applied to 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] With the rapid development of the national economy and the continuous improvement of people's living standards, the demand for electricity has increased sharply, and transmission lines are increasingly developing in the direction of large capacity, which requires increasing the transmission capacity of wires. Aluminum alloy conductors have been used in overhead lines as early as 1921. With the improvement of power transmission and transformation technology and the development of power transmission and transformation lines, aluminum alloy wires are increasingly showing their superiority. Since the 1950s, it has been widely used in Western Europe, Northern Europe, the United States, Canada, Japan and other countries. In France, more than 90% of the transmission lines use aluminum alloy conductors, and Japan has also reached mo...
