What is a copper wire
Copper wire or wire is a wire that has a string and is made of copper. Manufacturers today use copper only for works that require its properties because the price of copper has risen sharply and the number of buyers has fallen. Aluminum and steel are not good alternatives to copper, but their malleability and conductivity make them a substitute for copper in these situations. Copper wire has interesting properties and despite being soft and flexible, it is very strong and durable.
Each of us has certainly had encounters with copper wire or copper wire in our lives and have touched them closely. Like me, you have probably tried several times to break these copper wires, but you did not succeed. It is interesting to know that this feature has caused copper to find a special place in various industries.
Copper and copper wire are used in handicrafts, wood and woodworking, agriculture, electricity and industry.
As mentioned, copper wires and wires can generally be made of aluminum and steel, except for copper, the material of which is determined according to the opinion of the manufacturer and the needs of the consumer. If the material of the wire is steel, it has high conductivity properties and the absence of magnetic properties, such as copper retention, but it does not have the softness and flexibility of copper. For this reason, the priority of manufacturers who want their product to be quality is to use copper.
Aluminum wires are also a type of wire that is also used in the medical industry. There are some things to keep in mind when producing this type of wire. This wire, which is used in sections above ten, has less conductive properties than copper and steel and are not so-called conductors. For this reason, they are not a good alternative to copper, but they are similar in terms of flexibility and strength
They are not, but they are very similar to copper in terms of flexibility and strength. Also, the strength of copper is much higher than aluminum and steel.
Types of copper wires
There are many varieties of copper wire in the market, which are made for different industries in terms of properties and size. Round copper wire, flat copper wire, sprayed copper wire, semi-sprayed copper wire and copper wire are the types of copper wire that are produced in factories.
Specialized study of copper wire production process
According to international standards, two types of copper are produced, which are classified based on the amount of oxygen in them. The first category, called oxygen-free copper, has a standard index and symbol (Cu-Of) that contain 95.99% copper. In the production of the same type of copper, copper is made with an electronic index that contains 5 ppm of oxygen and 99.99% of pure copper, this type of copper is displayed with the symbol (Cu-OfE).
In the second batch production process, represented by the symbol Cu-ETP, the copper melt is controlled by an oxidizing atmosphere to give the final product 300 ppm of oxygen. This type of copper is called electrolytic copper. To produce copper wire, it tries to get all the oxygen in it
Copper wire is tried to remove all the oxygen in it, which to achieve this important, special method is used.
As mentioned, an oxidizing atmosphere is used to control the amount of oxygen in the electrolytic copper production process, along with elements such as phosphorus, aluminum, or calcium. It should be noted that the mentioned elements are the main factors in reducing oxygen. But there is a second way to reduce the amount of oxygen in copper, and that is to use carbon. The use of these elements is not suitable for reducing oxygen because if a small percentage of these elements are injected more than the required level of copper, some of its properties will be affected, including its conductivity, but the use of carbon to remove oxygen or low Measuring it is a good and appropriate solution that has no side effects and can be done easily. As mentioned, in the production stages of copper wire, the oxygen in it is removed to increase its purity and increase. Also, after going through these steps in making copper wire, lacquered wire is laid around each copper wire.
These wires are electrically insulated and secure the copper wires. The material of these insulators in the manufacture of copper wire is usually PVC polymer blend. It should be noted that copper wires are classified into two different types according to the voltage in the market. In the first type, these copper wires have the ability to pass electricity over 300 volts
In the first type, these copper wires have the ability to transmit electricity from 300 volts to 500 volts, and in the second type, these wires have the ability to transmit electricity from 450 volts to 750 volts per second. In general, the process of producing copper wire is as follows: the produced copper cathode is sent to a continuous casting unit, in which the copper wire, after packaging, weighs 5 mt and becomes a coil. Copper wire is produced and designed in four different sizes, each of which is used for different tasks. These wires are produced and packaged in sizes of eight, twelve, twenty-twenty-three millimeters.
