Copper Alloy Etching Precautions

In addition to being able to etch stainless steel, molybdenum and titanium materials in metal etching, one of the more special is copper etching. Compared with aluminum etching, copper etching is easier than aluminum processing, because the activity of aluminum is easy to produce strong chemical reactions such as high temperature when contacting with chemical agents, resulting in the increased complexity of its process. For copper etching, copper alloys are classified as brass, bronze There are three types of white copper, including red copper, oxygen-free copper, pure copper, etc. The etching solution of copper is different from that of stainless steel, and the waste liquid can be reused. However, due to the characteristics of copper, the reaction speed of copper etching solution in the etching process is fast, the use temperature is low, and the post-treatment is relatively easy, which has little environmental pollution. Copper etching has a wide range of applications, including copper eyeglass frame, copper gasket, copper handicraft, etc. The etching process of copper can meet the thickness of 0.01MM-2MM. Due to the oxidation of copper, attention should be paid to the surface treatment and the protection of copper in specific environment.
