Specifications of copper metal<\/h2>\n

Copper is a chemical element with the symbol cu \u200b\u200band has a very high flexibility and thermal conductivity. Copper is used as a building material and as a building material for various metal alloys such as sterling silver.<\/p>\n

Copper has the chemical properties of transition metals, has oxidation states of +1 and +4, its compounds are colored, with atomic number 29 and atomic mass of 546\/63.<\/p>\n

Various physical properties including copper<\/a> grade, amount of natural impurities or residues of additives formed at the boundary of solid solution grains or separate phases;\u00a0Mechanical and thermal pretreatment of metal, which leads to conditions such as cast copper, hot tubular copper and hard copper, molding copper, spitting copper, are other features of copper metal<\/a>.<\/p>\n

This element is one of the few metals that can be used in nature as a metallic form. For this reason, it has been used by humans in different regions throughout history. Of course, this is not only because of its abundant resources in nature but also because of its excellent properties.<\/p>\n

The metal is currently used in electricity, electronics, energy, petrochemicals, transportation, machinery, metallurgy and other new industries and some advanced fields.<\/p>\n

History of copper in the world and Iran<\/h3>\n
\n

Copper is the first element discovered by man after gold, and the copper tools discovered date back to around 5000 BC.\u00a0There are indications that copper was melted and purified from its oxides, such as malachite and azurite, by 5000 BC.<\/p>\n

Copper was first discovered in ancient Cyprus.\u00a0Copper was mined in Cyprus and has been used in various industries since that time.\u00a0Before the advent of metal smelting technology and knowledge, people heated copper metal and pounded it into sheets.<\/p>\n

The sheets were then sharpened with a hammer, resulting in the first copper knives.\u00a0And so began the history of copper.\u00a0The oldest metal objects found in present-day Iraq are in the area between the Tigris and Euphrates, which was a copper pendant and is estimated to be 8700 years old.<\/p>\n<\/div>\n

Properties of copper metal<\/h3>\n

Copper, silver and gold are in group 11 of the periodic table.\u00a0These three metals have high flexibility and electrical-thermal conductivity.\u00a0The metal is usually made in the form of fine-grained polycrystalline, which is stronger than single-crystal forms.<\/p>\n

The softness of this metal partly explains its high electrical and thermal conductivity.\u00a0After silver at room temperature has the highest temperature conductivity.\u00a0This is due to the low resistance of its electrons to mobility after heating.<\/p>\n

Copper is one of the few metallic elements with a natural non-gray or silver color.\u00a0Pure copper is reddish-orange in color and produces reddish spots when exposed to air.\u00a0The color of this metal is due to the electronic transfer between the filled atomic shells d3 and 4S semi-empty.<\/p>\n

Because the energy difference between these shells corresponds to the orange light.\u00a0Like other metals, galvanic corrosion will occur if this element comes in contact with another metal.<\/p>\n

The metal does not react with water but reacts slowly with atmospheric oxygen to form a layer of brownish-black copper oxide that protects the underlying metal from further corrosion, unlike iron rust.<\/p>\n

The green layer (copper carbonate) that is often seen in old structures such as the roofs of many old buildings and the Statue of Liberty is copper oxide. The metal reacts with certain sulfur compounds when they are exposed to form various sulfides.<\/p>\n

Copper alloys<\/h3>\n

Many alloys have been formulated for this metal, many of which have important applications.\u00a0For example, brass is an alloy of copper and zinc.\u00a0Bronze is commonly referred to as copper-tin alloys, but can also refer to any other alloy, such as aluminum bronze.<\/p>\n

This metal is one of the most important solder compounds of gold and silver that is used in the jewelry industry and changes the color, hardness and melting point of the resulting alloys.\u00a0Some lead-free solders are made of tin alloyed with small amounts of copper and other metals.<\/p>\n

Copper and nickel alloys in low value coins are often used for exterior cladding.\u00a0The alloy of 90% copper and 10% nickel is very significant due to its corrosion resistance and is used for various objects that are exposed to seawater.<\/p>\n

However, it is vulnerable to pollutant sulfides that are sometimes found in ports.\u00a0In addition, copper alloys with aluminum (about 7%) are golden in color and are used in decoration.<\/p>\n

Various applications of copper metal<\/h3>\n

The main applications of copper are power generation (60%), roofing and plumbing (20%) and industrial machinery (15%).\u00a0Copper is mostly used\u00a0<\/span>as a pure metal\u00a0<\/span>, but when more hardness is needed, it is placed in alloys such as brass and bronze.<\/span><\/p>\n

The metal has been used in boats and hulls for more than two centuries to control the growth of plants and oysters.\u00a0A small portion of copper resources are used for food supplements and fungicides in agriculture.\u00a0This metal is also used in machinery, but it is mostly used as an alloy, which is described below.<\/p>\n
