China's copper engraving industry network news China's copper engraving industry network to share the classification and advantages of copper relief Copper relief is one of the copper crafts. The copper relief has a long history and culture of thousands of years in the culture of the Chinese nation. It has formed many bronze sculptures, including text, images and sculptures. In ancient times, there was no copper relief in China. It was introduced to China from the West, and some were introduced to China from India. However, copper embossing is now very common in China, which is not only the cultural industry of Tang County, but also the industry of the Chinese nation. The following is a list of related reliefs for copper relief so that everyone can understand. The production of copper relief has been popular in China for a long time. Among them, there are three kinds of materials for making copper reliefs: red copper relief, brass relief, and wrought copper relief, while red copper relief is also called pure copper relief or copper. Embossed, red copper made relief has many advantages, because red copper is one of the relatively high content of metal, the conductivity is very good, and corrosion resistance, texture is very soft, good ductility. Because of its soft nature, red copper is easy to use during engraving. But one of the biggest shortcomings of red copper is the high melting point. It is difficult to master the crafts in the casting process. Brass relief is made from brass, a brass bronze sculpture can exhibit a variety of effects, which in the production process, the chemical solution should be added generally at room temperature after fermentation oxide, without damaging the brass of Next, refine a black oxidizing substance, and then manually process it to show a variety of copper rhyme. The wrought copper relief is also called the name, one is called copper knocking, the other is called copper. Bronze embossing is the use of the ductility of brass, coupled with the engraving technique of the engraving technician, to form a unique copper relief. The craftsmanship is classic.
