Embodiment 1

[0018] An aluminum-based alloy containing In and Li with solidification characteristics of Lima alloy. In terms of weight percentage, the composition of the alloy is Li: 0.5wt.%, Mg: 2.0wt.%, In: 4.0wt.%, Bi: 2.0wt.%, Ge: 1.0wt.%, Sn: 5.0wt.% , Th: 0.2wt.%, Ag: 1.0wt.%, the balance is aluminum. The above-mentioned In- and Li-containing aluminum-based alloy with the solidification characteristics of Lima alloy includes the following steps: adding the above-mentioned proportion of raw materials into an induction furnace in an argon atmosphere, and using a graphite crucible; heat preservation at 700 degrees during smelting For 10 minutes, stir evenly by high-frequency induction furnace electromagnetic stirring; after stirring evenly, keep it at 700°C for 1 minute and cast out of the furnace; alloy casting adopts a steel mold with a diameter of 20-30mm, and adopts a water cooling method to cool down. The resulting ingot is heated to 650-700 degrees at room temperature and kept for...

Abstract

The invention discloses an aluminum-based alloy containing In and Li and having a Lima alloy solidification characteristic. The alloy comprises, by weight percentage, 0.5-1.0 wt.% of Li, 2.0-3.0 wt.%of Mg, 4.0-4.5 wt.% of In, 2.0-3.0 wt.% of Bi, 1.0-2.0 wt.% of Ge, 5.0-8.0 wt.% of Sn, 0.2-0.4 wt.% of Th, 1.0-2.0 wt.% of Ag and the balance aluminum. The material provides a lightweight solution scheme of a substitute product for a Lima alloy for bronze statue casting in the Tibetan area in China, that is, a novel aluminum alloy for casting is provided. Implementing and industrializing of the material can effectively promote updating of new materials in the region ornament industry in China and the industry upgrading requirement.

Description

Technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum alloy. Background technique [0002] Tibetan Buddhism was formed in the 10th century, and the existence of bronze statues in Tibetan religious activities dates back to the time when Buddhism was first spread in the Tubo Dynasty. In the history of Tibetan Buddhism that has lasted for more than a thousand years, countless Buddha statues have been enshrined in temples and families as carriers of faith. As a form of artistic expression, bronze Buddha statues occupy a prominent position in the religious culture of Tibetan Buddhism and represent the highest achievement of Tibetan art and traditional skills. These cultural treasures embodies the superb smelting skills and splendid culture in ancient my country. [0003] There are two traditional casting methods for bronze Buddha statues in Tibet: lost wax casting and Shafan casting. The overall dimensions of the bronze Buddha sta...
