Title:
HIGH-CONDUCTIVITY ALUMINUM ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/119501
Kind Code:
A1
Abstract:
A high-conductivity aluminum alloy, comprising the following components in percentage by weight: 85 to 90% of Al, 6.5 to 8.5% of Si, 0.5 to 0. 8% of Fe, 0.1-0.5% of Zn, 0.01-0.015% of V, and 0.012-0.03% of Sr. According to the high-conductivity aluminum alloy, alloying elements such as Si, Fe, and Zn are optimized, elements such as Sr and V are added, the content of each component is controlled, and the components coordinate with each other. The aluminum alloy has high conductivity, good casting performance, and excellent semi-solid die casting performance. In the high-conductivity aluminum alloy, strontium (Sr) is introduced to replace the sodium (Na) in a conventional process to refine and modify eutectic silicon. Compared with conventional aluminum alloy to which Na is added, the high-conductivity aluminum alloy has the advantages of stability, long duration, and good reproducibility while avoiding gettering caused by the refinement and modification of conventional element Na.
