Copper is a metal element, but also a transition element, chemical symbol Cu, English copper, atomic number 29. pure copper is a soft metal, the surface just cut for the reddish-orange with a metallic luster, the monomers are purplish-red. Good ductility, thermal conductivity and high electrical conductivity, so in the cable and electrical and electronic components is the most commonly used materials, can also be used as building materials, can be composed of numerous kinds of alloys. Copper alloys have excellent mechanical properties and low electrical resistivity, the most important of which are bronze and brass. In addition, copper is a durable metal that can be recycled many times without loss of mechanical properties.
Copper is a metallic chemical element and an essential trace element for the human body. Copper is also the first metal discovered by mankind and is widely used by mankind as a heavy metal. As early as in prehistoric times, people began to dig open-pit copper mines and used the copper obtained to make weapons, tools and other utensils, and the use of copper had a profound impact on the progress of early human civilization. Copper is a metal found in the earth's crust and in the oceans. The content of copper in the earth's crust is about 0.01%, and in individual copper deposits, the content of copper can reach 3% to 5%. Most of the copper in nature exists as compounds, i.e. copper ores. Copper minerals and other minerals are polymerized to form copper ore, which is mined and beneficiated to become a copper concentrate with a high copper content. It is the only metal that can be produced naturally in large quantities, and also exists in various ores (e.g. chalcopyrite, chalcopyrite, porphyry, chalcopyrite and malachite), and can be used in the form of monomorphic metal states as well as brass, bronze and other alloys for industrial, engineering and technological purposes.
Copper is widely used in the electronics industry and aerospace because of its excellent electrical conductivity its electrical resistance and thermal conductivity are several times that of other materials. In addition, due to copper's high electrical conductivity, it has the ability to oxidize rust, which prevents electronic components from developing problems in humid or high temperature environments.
Copper is also used in large quantities in the aerospace field because it has excellent mechanical strength, ductility and corrosion resistance, and is not easily damaged, and can be applied to different space environments, such as high temperature, high pressure, humidity and other conditions, and is widely used in the structural components of carrier rockets and spacecraft. In addition, due to copper's excellent thermal conductivity, it can help airborne electronic equipment to maintain temperature, and can be used to manufacture impact-resistant optical storage components.
Copper can also be used in the medical field. It can be used meter to manufacture surgical instruments, ear cupping paper, therapeutic instruments, etc. Because of its corrosion resistance, thermal conductivity, and other properties, it can ensure the herbability and safety of medical equipment. In addition, copper can also be used in oral care, to help protect teeth, antibacterial, to prevent dental corrosion.
In addition, copper can also be used in the marine industry, which can help extend the life of the ship, enhance the durability of the ship in the sea, but also can resist corrosion in the marine environment to reduce the possibility of damage to the ship.
In addition to the above mentioned fields, copper can also be used in other fields, such as power field water treatment field, metallurgical field and construction field, its excellent performance and stability can meet the needs of different industrial production.
In conclusion, copper has an important role in electronics, aviation, medical, marine and other industrial production, it has excellent electrical conductivity, thermal conductivity and magnetic conductivity, strong corrosion resistance, thermal conductivity, excellent mechanical strength, can be widely used in different space environments and industrial fields, can be described as a multi-purpose material.
