Abstract

The invention discloses a lead-free high-hardness yellow Lima alloy for cast Buddha figures in the Tibetan region and a process thereof. The alloy comprises the following components in percentage by weight: 0.6-0.8 wt.% of Ba, 5.0-8.0 wt.% of Mg, 12.0-14.0 wt.% of Zn, 4.0-6.0 wt.% of Bi, 3.0-4.0 wt.% of Sb, 1.0-2.0 wt.% of Mo, 2.0-3.0 wt.% of Au, 18.0-24.0 wt.%, and the balance of copper. The material provides a lead-free and mercury-free new material scheme to the Lima alloy for bronze statue casting in the Tibetan region; and the obtained product achieves excellent yellow appearance. Throughimplementation and industrialization of the material, the new material updating and industrial updating demands can be effectively promoted.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a copper alloy. Background technique [0002] The copper casting process has a long history in our country, and it appeared as early as the Shang and Zhou dynasties. The early copper casting process was mostly used for casting Buddha statues, which has low cost and great flexibility. The production process of copper Buddha statues in Tibet is divided into two categories: one is the casting process, and the cast bronze Buddha statues are mainly small Buddha statues. The other category is the craftsmanship of making Buddha statues, mainly large Buddha statues. These cultural treasures embody the superb casting skills and splendid culture in ancient my country. [0003] There are currently two known casting processes for bronze Buddha statues: the lost wax method and the sand fan method. [0004] (1) Lost wax method. The principle is to use wax to make the same mold as the casti...
