Abstract

The invention discloses aluminum alloy. The aluminum alloy is prepared from the following raw materials in parts by weight: 100 to 102 parts of aluminum, 2 to 4 parts of iron, 3 to 5 parts of copper, 4 to 6 parts of titanium, 1 to 3 parts of zinc, 4 to 6 parts of chromium, 2 to 4 parts of cerium, 1 to 3 parts of dysprosium, 4 to 6 parts of holmium, 1 to 3 parts of thulium, 2 to 4 parts of potassium chloride, 1 to 3 parts of sodium aluminum fluoride,, 1 to 3 parts of hexafluorobenzene, 2 to 4 parts of calcium sulfide, 1 to 3 parts of sodium sulfate, 3 to 5 parts of silica fume and 7 to 9 parts of cobalt powder. The aluminum alloy is high in strength.

Description

technical field [0001] The invention relates to an aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy is currently the most widely used alloy. Alumina was reduced to aluminum by electrolysis in the laboratory in 1808, and it has been used as a building material on the spire of the Washington Monument in the United States since 1884; the aluminum alloy material synthesized by adding various metal elements to aluminum has been widely used in the construction industry in every aspect. [0003] In 1908, Alcoa invented the el...
