Copper

The copper is characterized by its yellow color to reddish, and a metallic element, its chemical symbol Cu, atomic number 29, and is melting at 1083 ° C, and is found by nature alone or in the form of oxides, and is very easy to control copper is capable of formation, and is one of the oldest minerals discovered and used in the manufacture of batteries, electrical equipment, and wires as a heat conductant.

Copper is also used in the manufacture of cooking utensils and is used in the manufacture of gold bullion, which is added in small quantities to give gold the necessary hardness, as well as in the manufacture of coins, military equipment, and some musical instruments, and features the following characteristics.

Characteristics of Copper

• Thermal conductivity: When the electrical conductivity is similar, the copper enters the electrical current, because it is resistant to corrosion and loss of conductivity.
• Color and Appearance: Copper is characterized by its color that changes with the body’s conditions. The color of the alloy may be pink, yellow, bronze gold, or green depending on the conditions in it. Copper alloys are involved in the manufacture of decorative applications.
• Corrosion Resistance All copper alloys are resistant to corrosion in fresh water, steam, and rural, marine and industrial environments. Copper is well resistant to saline and kaolin solutions, soil, non-oxidizing minerals such as nitric acid, organic acids, ammonia, halogens and sulfides, poor for inorganic acids.
• Softness: The copper softness can be restored, with specific hardening, or occasional wear during the welding process.

Importance of copper food

• It protects the body from anemia.
• The body contains about 100 mg of copper.
• Its deficiency in the body works on growth disorders and can be obtained from meat, yolks, fruits, and vegetables.

Risks of copper

• The risk of infection with the mineral fever, which causes the pollution of fresh water copper to the disease, which is similar to the flu, and cured these symptoms within two days, where the person is due to excessive sensitivity to copper, and may lead to irritation of the nose and eyes, headaches, diarrhea and vomiting , and long-term stomach pain.
• Kidney and liver atrophy, due to the entry of large amounts of copper to the body, may lead to death in some cases, and some recent studies say that there is a relationship between the increased concentration of copper body, and low mental abilities of adolescents.
• The occurrence of smoking is caused by exposure to copper smoke, and with severe exposure to Wilson’s disease, its symptoms are liver fibrosis, damage to brain cells, kidney disease, and corneal deposition.
