Copper processing advantages and disadvantages


Copper processing is mainly to see his color, copper, copper is good copper. Brass, the color of the hair light. A copper-plated zinc, tin plating, white, is poor quality copper, copper impurities, bent down into two pieces by hand, with black impurities.

Copper was one of the first to find old metals, and people started using copper as early as three thousand years ago. Copper processing weight, density 8.92 63.54,1083 (c) of the melting point, the boiling point is 2.567 degrees Celsius. There are light pink or red copper, copper oxide film formed surface, it looks like copper. Copper has many valuable physical and chemical properties, such as thermal conductivity and conductivity are very stable chemical substances, tensile strength, easy to weld, corrosion resistance, plasticity, ductility. Pure brass components can be drawn into filaments, made of thin copper foil. Copper forms alloys with zinc, tin, lead, manganese, cobalt, nickel, aluminum, iron, and other metals.

Copper is an elemental pro- tein. In nature, copper is processed only by the formation of sulfides of nitrogen oxides under strong oxidizing conditions and natural copper that can form under reducing conditions. At present, there are over 50 types of Cu-containing copper oxides, sulfides and similar compounds in the earth's crust and natural copper and copper sulfate, carbonate, silicate minerals. There, metallurgical conditions are currently available as industrial mineral raw materials16. Natural elements: natural copper copper sulphides: chalcopyrite, bornite, chalcocite, copper blue, lady, sulfur, copper, tetrahedrite, fahlerz arsenic copper copper oxide: red copper and black copper copper sulphate, Carbonate and Silicate Minerals: Malachite, Azurite, Chrysocolla, Water, Copper Sulfate, Copper Chloride.
