Copper Machining

According to the color, it can be divided into 1. Brass: refers to the alloy based on copper and zinc, and can be subdivided into simple brass and complex brass. The third group of complex brass is called nickel brass. , silicon brass, etc.; 2. Bronze: refers to copper-based alloys other than copper-nickel and copper-zinc alloys. The main varieties are tin bronze, aluminum bronze, and special bronze (also known as high-copper alloy); 3. White copper: refers to Copper-nickel alloy; 4. Red copper: refers to pure copper, the main varieties are oxygen-free copper, red copper, phosphorus deoxidized copper, silver copper.

Copper chemical polishing agent is a new type of chemical polishing agent, which is widely used in the surface bright treatment of brass, red copper and beryllium copper. Compared with mechanical polishing and electrochemical polishing, chemical polishing does not require electricity and special mechanical polishing equipment. For copper parts with complex shapes, it can also be easily handled, and the production efficiency is high.

Through the copper chemical polishing process, copper parts with good decorative effect and good surface performance can be obtained. In the process of using copper chemical polishing liquid, it is necessary to make the ratio according to the ratio in the manual. Before polishing, the oil on the surface of the copper parts must be cleaned. The workpiece should not be placed too much at one time. During the polishing process, the copper parts need to be turned all the time , so that it fully reacts with the polishing solution. After polishing and removing the film, it needs to be washed with water before passivation and protection can be performed.
