Preparation method of 24K pure gold simulated Cu-Zn alloy

The invention provides a preparation method of a 24K pure gold simulated Cu-Zn alloy, and relates to a Cu-Zn alloy. The alloy is prepared from, by mass, 51-65% of Cu, 0.1-5.0% of Al, 0.01-1.0% of X, 0.05-3.0% of Y and the balance Zn. The alloy is mainly characterized in the variety and ratios of the microelements X and Y and the gold simulation heat treatment technology after casting forming. By adopting the preferential preparation method, the Cu-Zn alloy with the natural color and surface color approximate to 24K pure gold can be obtained, and used for manufacturing sculptures, decorates andother artwork. The preparation method of the 24K pure gold simulated brass block materials has the advantages that the cost is low, environmental protection is achieved, and the process is easy to control. 本发明提供种仿24K纯金的Cu-Zn合金制备方法。涉及的种Cu-Zn合金，其化学成分质量百分比为：Cu(51～65％)-Al(0.1～5.0％)-X(0.01～1.0％)-Y(0.05～3.0％)-Zn(余量)，其主要特征在于微量元素X、Y的种类和比例，以及铸造成形后的仿金化热处理工艺。采用本发明经优选的制备方法，可获得本色和表面颜色均接近24K纯金的Cu-Zn合金，用于制作雕塑、装饰等艺术品。本发明的仿24K纯金黄铜块体材料制备方
