Imitation 24 K gold heat treatment method of copper-aluminum alloy

Abstract

The invention provides an imitation 24 K gold heat treatment method of copper-aluminum alloy and relates to an imitation gold heat treatment process of copper and aluminum multicomponent alloy. Low-temperature segmented heat preservation and heated air circulation are adopted, so that a firm imitation gold film layer is formed on the surface of the alloy, and the color of the imitation gold film layer is similar to that of 24 K pure gold. By adopting the optimized heat treatment method, the imitation gold copper-aluminum alloy gorgeous in color can be obtained and is used for manufacturing artworks, ornament products and gold statue products. According to the imitation 24 K gold heat treatment method of the copper-aluminum alloy, copper alloy is treated through the heat treatment process, so that the color of the copper alloy is similar to that of the 24 K pure gold; and the advantages of being environmentally friendly, convenient, quick and the like are achieved.

Description

technical field [0001] The invention relates to a 24K gold imitation heat treatment method for copper and aluminum alloys, which belongs to the metal surface treatment technology. Background technique [0002] 24K gold refers to pure gold with a gold content of more than 99.99% in the market, which is usually called pure gold or pure gold. At all times and in all over the world, gold has been used to make jewelry, sculptures and other works of art because of its beautiful golden yellow color and stable chemical properties. However, due to its limited storage and high price, it is difficult to obtain large-scale applications. Especially for large-scale works of art, such as Buddha statues, 24K pure gold cannot be used, so many gold crafts are gradually replaced by cheap, beautiful and various imitation gold alloys. Therefore, cheap and beautiful imitation gold alloy products have been widely valued by people, and among them, the imitation gold material with excellent compreh...
