Abstract

The invention discloses a lead-free and mercury-free Qinglima alloy for Tibetan Buddha statues with spinodal decomposition characteristic. The alloy is prepared from the following components in percentage by weight: 1.5 to 2.0 percent of Mg, 10.0 to 16.0 percent of Sn, 0.4 to 0.6 percent of Y, 12.0 to 14.0 percent of Bi, 4.0 to 4.5 percent of Sb, 6.0 to 8.0 percent of Fe, 4.0 to 5.0 percent of Au,12.0 to 15.0 percent of Ag and the balance of copper. By adopting the lead-free and mercury-free Qinglima alloy, a new lead-free and mercury-free material scheme is provided for Lima alloy used in bronze statue casting in Tibetan region of China, and products obtained have excellent green appearance. The implementation and industrialization of the material can effectively promote the renewal of new materials and the upgrading needs of the religious jewelry 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] Tibet is located on the Qinghai-Tibet Plateau known as the roof of the world, where the Tibetan people have settled and nomadic for generations. The integration of Buddhism and local inherent religious culture has produced unique Tibetan Buddhism. The art of Tibetan Buddhist bronze Buddha statues has become the representative of the highest achievement of Tibetan art and traditional skills due to its prominent position in temple culture. The achievement of the art of Tibetan Buddhist bronze Buddha statues is inseparable from the craftsmen's proficiency in the properties of copper alloys and forging and casting techniques, as well as the strict observance of Buddhist images and measurement ratios. Due to the vast territory of Tibet, the inherent factors of each region and the influence in the process of formation and development are n...
