Xin Bo punching network punching network copper production plant for the processing of raw materials is the use of copper punching from. China's general habit of dark color, copper and copper alloy divided into four categories: brass, copper, copper-nickel alloy, bronze. First, the brass: refers to the copper and zinc-based alloy, it can be subdivided into simple and complex brass brass, brass complex again named as the third component of nickel, brass, silicon brass; yellow Copper is more of an alloy made of two or more constituent elements called special brass. The copper alloy of lead, tin, manganese, nickel, iron, silicon composition. Brass has strong wear resistance. Special brass special brass called it high strength, hardness, resistance to chemical corrosion. Second, copper: refers to copper, the main varieties of oxygen-free copper, copper, phosphorus deoxidized copper, silver and copper; namely copper copper copper price is high, also known as copper has good electrical conductivity and thermal conductivity, plastic pole. good, easy hot and cold pressure processing. Elemental copper is copper. Because color is purple and the name. See the various properties of copper. Copper was purple because of the name. Third, the copper-nickel alloy: means a copper-nickel alloy; copper-based nickel as the main element of copper-based alloy, silver-white, metallic luster, named copper-nickel alloy. Between copper and nickel may be another solution unlimited, to form a continuous solid solution, that regardless of how much the proportion of each other, and are fixed to α-- single phase alloys. Fourth, bronze: that in addition to copper-nickel, copper-zinc alloy of copper-based alloy, the main varieties of bronze, aluminum bronze, special bronze (also known as high-copper alloy); Bronze is the first application of an alloy in history, originally referred to copper-tin alloy, because of the color was gray, so called bronze. In order to improve process performance and mechanical properties of the alloy, most of the bronze also joined other alloying elements, such as lead, zinc, and phosphorus. Since tin is a scarce element, so the industry also uses a lot of Wuxi tin-free bronze, they are not only cheap, but also has the required special properties. Wuxi bronze mainly aluminum bronze, beryllium copper, manganese bronze, silicon bronze. Explanation More products please visit the website http://www.ap-xinbai.com
