The types of copper scrap are generally divided into two categories: household scrap and copper scrap. The price of this product is calculated per kg or ton. For example, it is better to manufacture industrial equipment and parts than to recycle the copper containers that are ubiquitous in the kitchen; it should not be used, and all copper shavings, whether domestic or industrial, must be separated before entering the factory. It is true that copper metal is very flexible, but to transfer the process of recycling copper scrap to copper ingots, it is best to separate household and industrial copper scrap. Interestingly, Iran's share of industrial copper recycling is much higher than household waste recycling. Knowledge of copper scrap of different agesDaily and industrial waste are divided into two categories of old and new copper recycling waste by age. New copper shavings, as the name suggests; it is not used and is a result of wasted production. The color of copper scrap is bright red and the purity is high, so the price is higher. Most of these copper scraps are turned into powder by the destruction device and then enter the reproduction cycle. Old copper shavings are also known for their names. These residues are worn from hard use and turn from red to brown. The rusty parts of this waste are green due to the presence of copper oxide.
These scraps are of lower purity and are therefore cheaper than new scrap copper. To distinguish between old and new copper waste, just make a small scratch on the surface; if you wear it, you will see bright colors. Understand the cycle of copper scrap from consumption to recycling Now you have understood the two main phases of the recycling cycle and realized that once collected, they are transferred to specialized factories of battalions, companies, etc. Join us now to learn more about one of the important advantages of copper scrap . Of course, the benefits of this precious metal are many. There is no non-recyclable waste in the recycling process for recycled copper Interestingly, copper scrap recycling has a higher priority than recycling other metals, even silver and gold, due to its wide range of uses in industry. In addition, copper has the least waste and the highest productivity compared to other metals, which helps protect the environment. Economical and cheap recycling of copper scrapAnother advantage of recycling copper scrap is that the cost of recycling copper scrap is lower than other metals, which is why capitalists and factory owners prefer this industry. Easy separation and sorting during copper scrap recycling Another advantage of the scrap copper recycling process is the ease of separation and cleaning. The process of recycling plastic waste and other metals faces many problems. But in copper recycling there are no difficult and complicated separations. So the cost of recovery is also reduced.
Rapid recovery of copper scrapHigh speed is another major advantage of copper scrap recycling. Because in the process of recycling copper scrap, advanced separation and cleaning devices are used. The waste recycling process is faster by using advanced and modern cleaning lines. So you become profitable faster. Collect and deliver copper scrap to copper plantsAt this stage, all household and industrial scrap is transferred to warehouses and copper production facilities.Manual separation and recovery of copper scrap Once shipped to the factory, the copper pieces are separated by hand with simple tools.Clean recycled copper materialAfter the copper scrap is separated, everything is cleaned with special equipment.Use a grinder (if necessary) Sometimes, in order to quickly melt the recovered copper pieces, all the scraps are poured into the grinder and turned into powder. Interestingly, some shredders have the ability to separate impurities and impurities. Bulk Recycling Scrap Copper Press If the copper scrap is large, in this case a press will be needed to compress and make smaller parts. For example, copper parts for cars are put into punching machines to melt them better and reduce their volume.
Smelting of copper parts and scrap The cleaned copper shavings are fed into a special hot furnace, where they become liquid through high temperatures and reach their melting point. Thus gradually into the use cycle. Molten copper is formed Finally, after the copper piece has reached the melting point, the copper liquid is poured into a special mold and taken out in the form of an ingot for repeated use. In this way, the recovered copper scrap can be put back into the consumption cycle. Learn about the types of copper scrap Copper shavings are copper items that the owner can no longer use or does not want to use. Some of these copper products can be recycled without recycling the copper. For example, if old copper cutlery is treated with polishing oil, it will become as black or burnt brown as it was the first day, and you can use the cutlery again. In addition, there is some electrical or electronic equipment that can be repaired and can be used again through repairs. In any case, many appliances that use copper end up as scrap, and by selling it to scrap buyers, you can put them back into the production cycle, helping the environment, and creating jobs and the nation's economy. Scrap copper container: As previously mentioned, one of the most important uses of copper over the past few years has been the manufacture of copper containers. Most of these containers are old and heavy and therefore contain a lot of copper. Besides the heavy weight of copper containers, their excellent alloys have also made them interesting to scrap copper buyers.
Scrap copper wire and cable: Copper is considered to be the best electrical conductor after silver, and because it is much cheaper than silver, it is used to make wires and cables. Some copper wires and cables used for power transmission do not require coating and are not coated. Therefore, they can be easily reused. The alloy quality of this type of copper scrap is second. Armature scrap copper: This scrap copper is associated with motors for electrical equipment that use copper windings. Of course, it's good to know that some of these motors don't have copper wires, just a copper coating over the aluminum wires. For example, there are two types of generator coolers: One is copper wire, which has a longer life and a higher price. The other is aluminum wire, which has a copper coating on it, so it has a shorter life and a lower price, which can be considered when buying. This copper scrap ranks third in alloy and value among copper scrap. Copper Clad Wire Scrap: Most wiring used in buildings is copper clad with a plastic cover over it to keep it safe and prevent electric shock or fire. In this way, to recycle the copper shavings from the sheathed wires, their plastic coating must be removed, which can be done in two ways: Remove the cover: Some of these copper-clad wires are ready for recycling in workshops that have the proper scissors to remove the plastic coating from the wires. Of course, there are also some small workshops that melt copper scrap. For example, some chandelier factories make copper chandeliers by melting copper shavings. Incineration of scrap copper-clad wire: In many cases, these coated copper wires are burned to melt the plastic coating and separate it from the copper. While this works and the copper is separated from the plastic, this work has two distinct drawbacks: Firstly, it causes a lot of pollution, which is not good at all. Another thing is that by burning copper shavings, their alloys decrease and lose their original value. While its copper is still usable, it has the lowest alloy content of all types of copper scrap.
copper price per kg
Copper, silver, and metals have a price per kg. These three metals are very flexible and conductive. This metal is usually produced in a fine-grained polycrystalline form, which is stronger than the single-crystalline form. The softness of this metal partly explains its high electrical and thermal conductivity, so it has the highest thermal conductivity at room temperature after silver. This is due to the low resistance of its electrons to mobility after heating. Copper is one of the few metallic elements that has a natural color other than gray or silver. Pure copper has a reddish-orange color and can produce reddish spots when exposed to air. The metal's color comes from electronic transitions between filled d3 and half-empty 4S atomic shells, as the energy difference between these shells corresponds to orange light. Like other metals, if this element comes into contact with another metal, galvanic corrosion will occur. Instead of reacting with water, the metal slowly reacts with atmospheric oxygen to form a brown-black layer of copper oxide that, unlike rust, protects the underlying metal from further corrosion. A green layer (copper carbonate) often seen on the roofs of many older buildings and in older structures such as the Statue of Liberty is copper oxide. When this metal is exposed to some sulfur compounds, it reacts with them to form various sulfides.
copper alloy Several alloys have been formulated for this metal, many of which have important uses. For example, brass is an alloy of copper and zinc. Bronze usually refers to a tin-copper alloy, but can also refer to any other alloy, such as aluminum bronze. This metal is one of the most important welding compounds for gold and silver used in the jewelry industry and changes the color, hardness and melting point of the resulting alloy. Some lead-free solders consist of tin with small amounts of copper and other metals. Copper-nickel alloys are often used for outer coatings on low value coins. The 90% copper and 10% nickel alloy is notable for its corrosion resistance and is used in a variety of items exposed to seawater. Although it is susceptible to the polluting sulfides sometimes found in harbors. In addition, the alloy of copper and aluminum (about 7%) is golden yellow and is used for decoration. Various uses of metallic copper The main uses of copper are in the production of electrical wiring (60%), roofing and plumbing (20%) and industrial machinery (15%). Copper is used primarily as a pure metal, but it is alloyed with brass and bronze when greater hardness is required. For more than two centuries, the metal has been used in the hulls of boats to control the growth of plants and shellfish. A small part of copper resources is used in food supplements and fungicides in agriculture. This metal is also used in machinery, but primarily as an alloy, as described below.
Use in the electrical industry One of the most widespread uses of this metal is in power transmission equipment such as wires and cables, transformers, switches, parts and connectors. In addition, this material is used in electrical machine constructions such as stators, rotors as well as hollow wires, communication cables and residential circuits. Applications in the electronics industry This metal is used in vacuum electronics such as HF and UHF tubes, crossed wires and magnetrons. Copper printed circuits require large amounts of copper foil, and in integrated circuits this metal has replaced aluminum in silicon chips for connections. Applications in the energy and petrochemical industry The main condenser tubes and plates on coal-fired power plants in the energy industry are made of brass, bronze and copper-nickel. Solar heaters are also usually made of copper tubing. Various types of vessels, piping systems, filters, pumps and valves, evaporators and condensers and heat exchangers used in the petrochemical industry for storage of corrosive media are made of this metal alloy. Thanks to its corrosion resistance and water-soluble form of copper ions, the material has anti-corrosion properties that protect marine life from pollution. This element and its alloys are widely used in desalination systems and offshore drilling and other underground facilities.
