Embodiment 1
[0052] A colored copper alloy coloring solution, the components and content per liter are: 125g of copper sulfate, 10g of ammonium chloride, 40ml of ammonia, 12ml of acetic acid, and the balance is water.
[0053] An aluminum bronze alloy for colored coloring, the composition and mass content are: Cu: balance, Sn: 0.07%, Zn: 0.7%, Pb: 0.01%, P: 0.01%, Al: 10.4%, Fe: 2.6%, Mn: 0.3%, Si: 0.1%, other impurities: 1.5%.
[0054] The production method of colored copper alloy casting, the steps are as follows:
[0055] Step 1: Fully mix and configure the above colored copper alloy coloring solution;
[0056] Step 2: Make a mold for pouring, polish the mold and brush the inner surface with an alcohol-based zircon powder coating with a thickness of 0.2mm. The alcohol-based zircon powder coating contains alcohol. After the coating is evenly applied, Ignite the alcohol-based zircon powder coating and dry the surface of the mold; the alcohol-based zircon powder coating is a mixture of a...
