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:
- Aluminum coils are typically cut to size using specialized coil slitting machines. These machines have rotating circular blades that make precise cuts along the length of the coil. The coil is fed through the machine, and the blades cut the aluminum into the desired width. The cut pieces are then collected and further processed or used for various applications.
- Q:
- Outdoor or exposed applications can utilize aluminum coils. The reason behind this lies in aluminum's remarkable resistance to corrosion, rendering it appropriate for outdoor purposes. It develops a safeguarding oxide layer on the surface, preventing further oxidation. Furthermore, aluminum is renowned for its lightweight nature, durability, and impressive strength-to-weight ratio, making it a favored option for outdoor tasks where weight and durability are crucial aspects. Aluminum coils frequently find their use in outdoor applications like HVAC systems, roofing, gutters, and siding, as they possess the ability to withstand exposure to diverse weather conditions without compromising their performance or aesthetic appeal.
- Q:could you please help me find information of the element aluminum??? all the information i can get will be great... thanks very mucho.... who discovered? where can i find pictures of it?
- Aluminum is from team 3 and there for has 3 electrons in its outer shell and desires 5 to fill it. it rather is going to react with any factors from team 5 that want aluminum's 3 electrons.
- Q:
- Yes, aluminum coils can be used for automotive body panels. In fact, aluminum is a popular choice for car manufacturers due to its lightweight and corrosion-resistant properties, leading to improved fuel efficiency and longevity of the vehicle.
- Q:
- The dimensions of aluminum coils change with temperature variations, which is known as their thermal expansion properties. Aluminum has a relatively high coefficient of thermal expansion, causing it to expand and contract more than other materials when exposed to temperature changes. The coefficient of thermal expansion for aluminum is approximately 22.2 x 10^-6 per degree Celsius. This means that for every degree increase in temperature, the length, width, and thickness of the aluminum coils will increase by around 22.2 parts per million. Conversely, when the temperature decreases, the coils will contract accordingly. These thermal expansion properties have significant implications in various applications that involve the use of aluminum coils. For instance, in heating and cooling systems, it is crucial to carefully consider the expansion and contraction of aluminum coils caused by temperature changes to ensure proper functioning and prevent damage. Likewise, in construction, where aluminum coils are commonly used for roofing and cladding, understanding their thermal expansion properties is vital to avoid structural issues and maintain the building's integrity. It is worth noting that the coefficient of thermal expansion may slightly differ depending on the specific aluminum alloy used in the coils. Furthermore, factors like coil thickness and shape can also affect the thermal expansion behavior. Therefore, when working with aluminum coils, it is advisable to refer to the material specifications or seek guidance from experts to accurately determine the thermal expansion properties and incorporate them into the design and application processes.
- Q:
- Automotive body panels can indeed utilize aluminum coils. Being both lightweight and corrosion-resistant, aluminum proves to be a suitable material for automotive purposes. The employment of aluminum coils in body panels yields numerous benefits, such as enhanced fuel efficiency owing to the reduced vehicle weight, improved handling and maneuverability, and increased durability. Moreover, aluminum boasts high recyclability, rendering it an environmentally conscious alternative for automotive production. Numerous automakers have already begun integrating aluminum coils into their vehicles, and this trend is anticipated to persist as the industry aims for lighter and more environmentally sustainable automobiles.
- Q:
- The process of coil coating is commonly used to coat aluminum coils for color matching and aesthetic purposes. It is a continuous and highly automated process where a layer of paint or coating is applied onto the surface of the aluminum coil. To start the coil coating process, the aluminum coil is thoroughly cleaned to remove dirt, grease, and oxidation. This is done using chemical cleaning agents and mechanical scrubbing methods to ensure a clean and smooth surface. Once the cleaning process is complete, a primer is applied to the aluminum coil. The primer acts as a bonding agent, improving the adhesion of the subsequent layers of paint or coating. It also helps to prevent corrosion on the aluminum surface. After the primer is applied, the aluminum coil undergoes a series of rollers where the desired color coating is applied. This can be done through various methods such as coil coating, spray coating, or powder coating. Coil coating is the most common method, involving the application of a liquid paint or coating onto the metal coil surface. The coating is then cured or dried using heat to ensure proper adhesion and durability. In order to achieve color matching and aesthetic purposes, the paint or coating used is often customized to specific color palettes or customer requirements. This customization is achieved by using a wide range of pigments and additives that alter the color, texture, and gloss level of the coating. Furthermore, specialized coatings can be applied to aluminum coils to enhance their aesthetic properties. For example, there are coatings available that give the appearance of natural wood or stone, providing a more visually appealing finish. Overall, the process of coating aluminum coils for color matching and aesthetic purposes involves thorough cleaning, priming, and the application of customized paint or coatings. This ensures that the aluminum coils meet the desired aesthetics while also providing durability and protection against corrosion.
