Copper has excellent electrical and thermal conductivity, and its electrical conductivity and heat transfer coefficient are second only to silver and higher than all other metals. Copper is located in IB Group of the Periodic Table of Elements, which belongs to the same group as gold and silver. The elements in this group are characterized by good chemical stability. At the same time, copper and its alloys also have beautiful colors, making products of higher end.The application of copper focuses on its characteristics of conductivity, heat transfer, corrosion resistance and color. At the same time, copper also has a little-known special property: antibacterial property. Copper sulfate (green) is added to swimming pool water and a small amount of copper sulfate is added to livestock feed to prevent the reproduction and contact spread of bacteria. Door handles of foreign hotels and hospitals are made of copper alloy, the purpose of which is to reduce the contact and spread of bacteria.Copper is not easy to oxidize in the atmosphere, but a mixture of basic copper sulfate and basic copper carbonate (commonly known as verdigris) will slowly form on the surface in wet air containing SO2 and CO2. The microstructure of verdigris is fine and closely combined with copper matrix, which plays a protective role in preventing the matrix from further oxidation. Therefore, copper has good corrosion resistance in the atmosphere. The ionization potential of copper in water is +0.52(Cu+), and it will not discharge with H+ exchange electrons in water. Copper will react with H+ only when it is oxidized into ionic state, so copper is resistant to corrosion in water. Coins dug thousands of years ago at the bottom of the West Lake are intact, and copper pipes are still bright after one hundred years of use, which fully illustrates the problem. Copper also has good chloride ion corrosion resistance and corrosion resistance in seawater, which is unmatched by stainless steel.
