Product Description
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.
The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."

- Q: Are there any limitations on the coil flatness of aluminum coils?
- Yes, there are limitations on the coil flatness of aluminum coils. Aluminum coils, like any other metal coils, are subject to certain tolerances and limitations in terms of flatness. Flatness refers to the deviation of the coil surface from being perfectly flat. The American Society for Testing and Materials (ASTM) has established standards for measuring and evaluating the flatness of metal coils, including aluminum coils. These standards provide guidelines for manufacturers, suppliers, and customers to determine the acceptable level of flatness for a given application. The acceptable flatness of aluminum coils can vary depending on factors such as the thickness of the coil, the grade of aluminum used, and the intended use of the coil. Thinner coils generally have stricter flatness requirements compared to thicker ones, as they are more prone to distortion and waviness. Coil manufacturers employ various techniques to control and improve flatness, such as tension leveling, roller leveling, or corrective leveling. These processes help to reduce or eliminate any deviations in flatness that may occur during the coil manufacturing or processing stages. It is important to note that achieving perfect flatness in aluminum coils is not always possible due to the inherent properties of the metal. Aluminum has a tendency to exhibit some degree of natural springback, which can result in slight variations in flatness. However, these variations are typically within acceptable tolerances for most applications. Ultimately, the limitations on the coil flatness of aluminum coils depend on the specific requirements of the customer or industry. It is essential for manufacturers and suppliers to communicate and establish clear flatness specifications to ensure that the coils meet the desired quality standards.
- Q: Can aluminum coils be used for architectural applications?

Aluminum coils can be used for exterior cladding, roofing, facades, and even interior applications like ceilings and wall panels. The coils can be easily formed, cut, and shaped, allowing for flexibility in design and creative architectural solutions. Additionally, aluminum coils can be coated with various finishes, such as paint or anodized coatings, to provide enhanced aesthetics and durability. Overall, aluminum coils are a popular choice in the architectural industry due to their versatility, durability, and aesthetic appeal.
- Q: How are aluminum coils protected against scratches and damage?
- Aluminum coils are protected against scratches and damage through several methods. One common method is the application of a protective coating or film on the surface of the coil. This coating serves as a barrier between the coil and any potential sources of damage, such as abrasion or impact. Another way to protect aluminum coils is by using a process called coil coating. In this process, the coil is cleaned, pre-treated, and coated with a layer of protective paint or resin. This coating not only enhances the appearance of the coil but also provides a protective layer against scratches and other forms of damage. Additionally, during the manufacturing and handling process, aluminum coils are often wrapped or packaged in materials that provide cushioning and protection. This helps to prevent any scratches or dents that may occur during transportation or storage. Lastly, proper handling and storage practices play a crucial role in protecting aluminum coils against scratches and damage. It is important to handle the coils with care, using appropriate equipment and techniques to minimize the risk of scratching or other forms of damage. Storing the coils in a clean and dry environment can also help prevent any potential damage. Overall, a combination of protective coatings, coil coating processes, proper handling, and storage practices ensures that aluminum coils are well-protected against scratches and damage, maintaining their quality and appearance.
- Q: I have been reading up on thermite and the required ingredients. I have extremely fine aluminum powder from a small etch-a-sketch sitting on plastic wrap in my room. On the comments page of the site i got the thermite ingredients from, multiple people said that thermite could explose if you use too fine of a powder. I have also read that powdered aluminum can become very explosive when it is exposed to air or if it becomes damp. Ive gotten particulary worried because the humidity right now is 93%. So, is powdered aluminum too dangerous to have in house and is too fine powdered aluminum explosive when in thermite?
- Powdered aluminium isn't explosive, and any humidity or dampness in the air won't affect it. Really finely powedered aluminium is nothing but an extremely powerful reducing agent. In other words, it won't explode, but it will burn very fast and very hot. When combined with magnesium powder, it contributes to the nature of thermite in a reduction-oxidation reaction. On it's own however, as long as you keep it away from any open flames, it's perfectly safe. I should say; be very, very careful with making thermite. It's not explosive on it's own, but if you make it wrong, it can fizzle and pop and send molten metal flying your way.
- Q: Briefly describe the process of aluminum production from bauxite. Describe the electrolyte and write the anode and cathode half-reactions.
- Bauxite is dissolved in NaOH to remove impurities and form aluminum hydroxide; the aluminum hydroxide is then precipitated out, and water is removed to produce pure aluminum oxide (alumina). In aluminum production, alumina (Al2O3) is dissolved in molten cryolite (Na3AlF6). This molten mixture is then placed in a container with graphite electrodes (cathode and anode are both graphite). The molten mixture serves as the electrolyte. At the cathode: Al3+ (l) + 3e- ---- Al (l) Aluminum ions gather electrons to form aluminum metal, which is liquid due to the high temperatures. The molten metal sinks to the bottom of the container, and is piped off. At the anode: 2O2- (l) --- O2 (g) + 4e- The oxide ions from alumina lose their electrons to form oxygen gas.
- Q: I heared the aluminum weakens or melts.
- Mercury readily combines with aluminium to form a mercury-aluminum amalgam when the two pure metals come into contact. However, when the amalgam is exposed to air, the aluminium oxidizes, leaving behind mercury. The oxide flakes away, exposing more mercury amalgam, which repeats the process. This process continues until the supply of amalgam is exhausted, and since it releases mercury, a small amount of mercury can “eat through” a large amount of aluminium over time, by progressively forming amalgam and relinquishing the aluminium as oxide. Aluminium in air is normally protected by a thin layer of its own oxide, which is not porous to mercury. Mercury coming into contact with this oxide does no harm. However, if any elemental aluminium is exposed (even by a recent scratch), the mercury may combine with it, starting the process described above, and potentially damaging a large part of the aluminium before it finally ends.
- Q: Is it possible to utilize an electric iron that features an aluminum coil heater?
- <p>Yes, you can use an electric iron with an aluminum coil heater. Aluminum coil heaters are commonly used in electric irons due to their excellent heat conductivity and quick heat-up time. They distribute heat evenly and maintain a consistent temperature, making them ideal for ironing. However, it's important to follow the manufacturer's guidelines for use and maintenance to ensure safety and longevity of the iron.</p>
- Q: What is the maximum operating temperature for aluminum coils?
- The specific grade of aluminum used typically determines the maximum operating temperature for aluminum coils. Generally, aluminum has a high melting point of approximately 660 degrees Celsius (1220 degrees Fahrenheit), allowing it to endure high temperatures without melting or distorting. For common grades of aluminum, the maximum operating temperature usually ranges from 200 to 300 degrees Celsius (392 to 572 degrees Fahrenheit). However, it is important to consider factors like coil thickness and the intended application, as these can affect the temperature range. In instances where higher temperatures are anticipated, it is advisable to employ aluminum alloys specifically engineered to withstand such conditions. Aluminum alloy 6061, for example, can tolerate maximum operating temperatures of up to 400 degrees Celsius (752 degrees Fahrenheit) or even higher. To guarantee safe operation within temperature limits, it is always recommended to consult the manufacturer's specifications and guidelines for the specific aluminum coils being utilized.
- Q: Can recycled aluminum coils be reused to create new ones, or are they only suitable for disposal?
- <p>Old aluminum coils can indeed be recycled and used to make new ones. Recycling aluminum is an efficient process that conserves resources and reduces energy consumption compared to mining and refining new aluminum. The recycling process involves melting the old coils, which can then be reshaped into new coils without losing any of their properties. This makes recycling aluminum coils a sustainable and environmentally friendly alternative to disposal.</p>
- Q: How do aluminum coils contribute to thermal insulation in buildings?
- There are several ways in which aluminum coils contribute to thermal insulation in buildings. Firstly, due to its excellent heat conductivity, aluminum can effectively transfer heat away from the building's interior. This allows for efficient cooling during hot summer months, as the aluminum coils can absorb and release the heat, preventing it from entering the building. Secondly, aluminum coils can be integrated into HVAC systems to control the temperature inside the building. By circulating cool air through the coils, the aluminum helps maintain a comfortable temperature, reducing the need for excessive energy consumption. Additionally, aluminum coils can be used as part of a radiant barrier insulation system. This involves placing reflective aluminum foil on the inside of walls, roofs, or attics, which reflects radiant heat back towards its source. This prevents heat transfer into the building, keeping it cooler in the summer and reducing the need for air conditioning. Moreover, aluminum coils are lightweight and easy to install, making them a cost-effective choice for thermal insulation in buildings. They can be easily shaped and fitted into various spaces, ensuring optimal coverage and maximum thermal efficiency. In conclusion, aluminum coils are essential for thermal insulation as they effectively dissipate heat, regulate temperature, and reflect radiant heat. Their versatility and efficiency make them a valuable component in creating energy-efficient and comfortable environments within buildings.
