What really does make people concerned regarding the aluminum-made wire and cable is the question of which will the aluminum wire and cable corrode and will it be dangerous. A well-known form of deterioration that, in certain conditions, can be described as "life-threatening" is corrosion, which is typically defined as the process by which metals deteriorate as a result of the combined actions of oxygen, water, other metals, and salts. Corrosion can be thought of as "life-threatening" because it typically occurs when metals deteriorate as a result of the Deterioration brought induced by contact with oxygen Aluminum is quite susceptible to oxidation when it is exposed to air. An electrically insulating outer layer of oxide that is strongly bonded and formed quickly produces a hard outer layer surrounding the metal [1]. Copper, when exposed to air, oxidizes as well, albeit to a considerably smaller level than iron does. The oxide that forms is rather pliable and, in contrast to aluminum, is electrically conductive, albeit at a lower level of conductivity than the base metal. Galvanic corrosion When two different types of metals are brought into contact with one another and an electrolyte, a phenomenon known as galvanic corrosion can take place. This is by far the most prevalent source of corrosion for aluminum, which is a reactive metal that is part of the galvanic series. 
When aluminum is brought into touch with a substance that is more cathodic than it is, it takes on the role of a sacrificial anode and becomes susceptible to corrosion. Copper, which is considered to be a reasonably noble metal, typically does not demonstrate a significant amount of galvanic corrosion. The effects that rust has on things There are two primary explanations for why corrosion can become dangerous: Due to the loss of material and, as a consequence, the loss of essential functions of the aluminum conductor and the aluminum laminated covering, failure is unavoidable. The addition of a new resistance causes an increase in temperature, which ultimately leads to the component's failure. When thinking about how to install a connector, this is an extremely crucial point to keep in mind. Corrosion: aluminum vs. copper It is well accepted that corrosion of aluminum is a significant issue, but work is still being done to fully understand the process behind it, its impact on dependability [3, and the development of related protection solutions. However, oxidation is a phenomenon that must be taken into consideration while preparing junctions on aluminum conductors, and special care must be paid to the connector during this process. The oxide layer needs to be stripped away, and in many cases, an oxide-inhibiting substance can be used to cut down on the amount of oxidation that occurs. 
Copper does not suffer from the problem of corrosion. Copper is not affected by the majority of organic compounds and can continue to function indefinitely in the majority of industrial settings. After prolonged contact with the air, a green patina may develop on the surface of the object; nevertheless, this is a result of the protective surface film and does not indicate the presence of a damaging attack. Copper does not require any sort of protection, even when it is put to use in offshore sites where it is subjected to a salty environment; this is the case. Aluminum wire is commonly found inside the walls of many homes that were constructed in the 1960s or 1970s. These residences are in the majority. Aluminum is a material that has a low cost of production, and during this time period, electrical contractors used aluminum wiring instead of copper wiring because aluminum was thought to be a successful way to transmit and distribute electricity. This belief was based on the fact that aluminum was thought to be a successful way to transmit and distribute electricity. Homes that have aluminum wiring in their electrical systems are more likely to sustain damage from electrical fires and other risks. Because aluminum wiring is lighter than copper wiring, it prevents cables from sagging because of their weight difference. However, aluminum wire immediately shown that it posed a risk in both residential residences and business structures. This was the case. 
Some indications that aluminum wire is currently present in your home include the following: Aluminum wires have a distinct hue that allows them to be differentiated from wires made of other metals. The letters CO/ALR, which stand for "copper/aluminum revised," have been stamped on the binding terminals of wiring devices that are intended for use with aluminum wire. On the outside of the wire jackets made of plastic, you'll find the word "aluminum" or the initials "AL." Your house was either constructed or expanded somewhere between the years 1965 and 1976. Wiring made of aluminum can become disconnected from the screws that secure it to electrical outlets, switches, or lights. This can lead to a weak connection, which in turn can cause the wire to overheat. The heat can cause the metal to oxidize, which results in a connection that is much worse, produces even more heat, and can finally cause a fire to start. When compared to other, safer metals, such as copper, the following characteristics of aluminum make it an unsuitable material for use in electrical wiring: Greater resistance to electrical current. Because aluminum has a high resistance to the flow of electrical current, conductors made of aluminum will need to have a wider diameter to accommodate the same amperage as those made of copper. 
This is because aluminum has a higher resistance to the passage of electrical current. Less ductile. Copper, which is more ductile, can withstand more bending and other sorts of abuse before it begins to fatigue and break down than aluminum, which will do so much more quickly. The wire will eventually deteriorate due to fatigue, which will also increase its resistance to the flow of electrical current and cause an excessive amount of heat to build up. Galvanic corrosion. When aluminum comes into touch with certain types of metals that are not chemically equivalent to it, a process known as galvanic corrosion will take place. Oxidation. The condition of the wires outside will deteriorate if it is allowed to be exposed to oxygen in the air. Aluminum wire, on the other hand, oxidizes much more readily than copper wire does, and the byproduct of this process, aluminum oxide, is much less conductive than its counterpart, copper oxide. A greater capacity for molding. Because of its softness and malleability, aluminum is extremely susceptible to any kind of compression. If a screw on aluminum wiring has been over-tightened, the wire will continue to bend or "flow" even after the tightening has been stopped. 
This is because aluminum is ductile. Because of this deformation or "flow," there will be a loose connection, which will result in an increase in the electrical resistance in that area. Thermal expansion and contraction of a greater magnitude. Aluminum has much more expansion and contraction in response to variations in temperature than copper. Because of this process, the connections that are made between the wire and the gadget will deteriorate. Excessive vibration. As it travels through the wiring, an electric current causes vibrations. This kind of extreme vibration has the potential to cause connections to become unsecure. Repairing aluminum wiring in an improper manner, such as connecting aluminum wire to copper wire using copper twist-on wire connections, can make the situation considerably more severe and is potentially hazardous. The correct method for repairing aluminum wiring is to have a licensed electrical contractor connect the damaged wires to short sections of the copper wire using connectors that are crimped or screwed on, and these connections are developed expressly for this application.
