copper :

Copper is a relatively red copper Which has a very high electrical and thermal conductivity Because the copper artifacts discovered date back to 8700 BC, probably copper is the oldest metal used in human .

In addition to being found in various minerals, copper is also found in metallic form. According to U.S Geological Survey copper is the third most widely consumed metal in the world after iron and aluminum. 

About three-quarters of the metal is used to make electrical wires, communication cables and electronics . About two - thirds of the copper on earth is found in igneous rocks ( volcanic ) . and about a quarter in the sedimentary basin. This metal is flexible and pliable And conducts heat and electricity well. for this reason , it is widely used in electronics and suicide .

Electrical applications of copper metal 

Electricity industry is one of the largest consumers of copper because the best cheap metal is for electricity transmission. It also has a special standard compared to other transmitters. In addition, the exceptional strength of copper metal, its flexibility, and its resistance to corrosion and corrosion make it the preferred and safest conductor for wire construction.

Copper also in electrical cables are either insulation or not , and for low voltage applications Medium or high is used. This metal is a major component of efficient motors and converters. 

Copper in Electronics and Communications

Copper , a great conductor of electricity , is used in wires . These wires can end up in home appliances such as toasters or microwaves, as well as appliances such as washing machines and refrigerators. It is also used in home electrical wiring as well as wire in electronic toys such as action figures and remote control cars.

the use of optical fibers in the main lines of communications has led to a revolution in the telecommunications industry . Despite the exclusion of copper from part of the distribution system, the need for copper has increased in wire-connected communities. this metal is still a good source of transmission line segments . Also, internal sharing lines, local area networks, personal computers, and other hardware all require copper and its alloys, especially connectors.

(Digital Sharing Line Technology) Allows Copper Infrastructure and Existing Ordinary Telephone Cables to transmit information at a high speed. For Internet users, this technology means connecting to 1.5 bits per second instead of 56,000 bits per second.

semiconductors manufacturers have recently provided a copper chip. using this metal in the circuit of silicon chips , silicon chips have the ability to perform better at higher speeds .

Building and mansion

copper is used in construction and construction . The first is used in plumbing and roofing . it can also be used in frame and window frames and doors . To transfer heat to the interior of the building, even the length of the metal can be embedded in the ground . It is a deliberate environmental method to heat a building . it 's also quite recyclable .

Therefore, destroyed buildings can reuse their metal in subsequent constructions. 

In addition to their attractiveness to harsh weather conditions, copper roofs are very popular. In most popular buildings , commercial buildings and houses use this metal to resist rain and rain water . 

The glossy green color of the copper, which imparts a classic look of warmth and beauty to the copper, is the result of natural climate. Copper water supply and heating systems are a hallmark of valuable safety in buildings. 

copper and brass are substances used in piping , water pumps , valves , and home appliances . Unlike plastic pipes, this metal does not burn, melt or release toxic or harmful gases in the event of a fire. Copper pipes also protect water systems from deadly bacteria such as Legionella. 

The use of copper handles and plates ensures the use of the biological properties of copper and prevents the transmission of disease and germs.

Medical 

The antimicrobial properties of copper make it a popular metal in medicine . Several hospitals have tested by covering covered surfaces such as bed rails and buttons with metal alloys in an effort to slow hospital-acquired infections. 

"The metal kills microbes by interfering with the electrical charge of cell membranes," said Cassandra Salgado, a professor of infectious diseases and a hospital epidemiologist at South Carolina Medical University.

Types of copper and its alloys 

1. pure copper : 

Contains 99.3% or more of copper. 

2. Alloys with high copper content : 

They have a percentage of copper between 96% and 99.3% And , in order to achieve special properties , silver may also be added .

3. Rice : 

It has zinc as the main alloying element Other elements such as iron, aluminum, nickel and silicon are also added to improve the properties of the alloy. Rice has high corrosion resistance and tensile strength. 

4. Bronzes : 

They have tin as the only alloying element or the main alloying element . Today, bronze refers to copper alloys whose main alloy element is other than nickel and zinc.

5. Other alloy groups : 

cu - Ni alloys : 

As it is known from the name of the alloy , the main alloying element is nickel . This group can include other alloying elements, or just nickel, alone. 

CU-Ni-Zn alloys : 

This group contains zinc and nickel as the main alloying elements, other alloying elements may also be added to it.

Leaded copper : 

Leaded copper is a cast copper alloy with 20% or more lead additives. they also contain small amounts of silver but there are no tin or zinc elements in them .

6. special alloys : 

When alloys contain chemical compounds that do not fall into any of these categories, they are called special alloys.

Physical and chemical properties of copper 

copper specifications are naturally a heavy metal of pink with a soft structure . The boiling temperature is over 1000 ° C . Cuprum is a good conductor of electricity and heat And melts at a temperature of 1.084 degrees Celsius. The density of the metal is 8 / 8 g / cm3.
