Embodiment 1

[0020] A Bailima alloy for casting Buddha statues in Tibetan areas with lightweight characteristics and its technology. In terms of weight percentage, the composition of the alloy is Li: 1.5wt.%, Mg: 8.0wt.%, Sc: 0.2wt.%, Bi: 5.0wt.%, Ni: 5.0wt.%, Al: 20.0wt.% , Au: 2.0wt.%, Ag: 8.0wt.%, and the balance is copper. The above-mentioned Bailima alloy and its process for casting Buddha statues in Tibetan areas with lightweight features include the following steps: adding the raw materials in the above ratio into an induction furnace under an argon environment, and using a graphite crucible; melting at 1200 The temperature is kept at 1200°C for 10 minutes, and it is evenly stirred by high-frequency induction furnace electromagnetically; after stirring evenly, it is kept at 1200°C for 1 minute and cast out of the furnace; the alloy casting adopts a steel mold with a diameter of 20-30mm, and the temperature is cooled by water cooling. The obtained ingot is heated to 850-950 degrees ...

Abstract

The invention discloses a white-cooper alloy with light-weight characteristics used for Tibetan area buddha casting and a process of the white-cooper alloy. The alloy comprises the following components of, in percentage by weight, 1.5 wt.%-3.0 wt.% of Li, 8.0 wt.%-12.0 wt.% of Mg, 0.2 wt.%-0.4 wt.% of Sc, 5.0 wt.%-6.0 wt.% of Bi, 5.0 wt.%-8.0 wt.% of Ni, 20.0 wt.%-28.0 wt.% of Al, 2.0 wt.%-3.0 wt.% of Au, 8.0 wt.%-10.0 wt.% of Ag and the balance copper. The material provides a light-weight solution for the white-cooper alloy used for Tibetan area buddha casting, and the appearance of the obtained product has a white impression. The implementation and industrialization of the material can effectively promote the updating and industry upgrading requirements of new materials in the religiousdecoration industry in China.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a copper alloy. Background technique [0002] Tibetan Buddhism was formed in the 10th century AD, and the existence of bronze Buddha statues in Tibetan religious activities can be traced back to the era when Buddhism was first introduced 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 monasteries 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 achievements of Tibetan art and traditional skills. These cultural treasures embody the superb casting skills and splendid culture in ancient my country. [0003] There are two traditional copper Buddha casting methods in Tibet: lost wax casting and sand mold casting. The dimensions of the bronze ...
