Aluminum Coil: An Earth-Friendly Industrial Material

Whether a project calls for aluminum foil (thinner than 0.006 inches in thickness) or aluminum sheet (0.006 inches to 0.070 inches in thickness), aluminum coil is behind the manufacturing process. Aluminum coil is formed by taking one continuous strip of aluminum and coiling it into a roll.

Some of the advantages of aluminum coil is that it is lightweight, heavy duty and able to resist corrosion. By a process called anodizing, whereby the aluminum surface is coated with a protective oxide, that corrosion resistance can be improved even further. As a result, manufacturers who need to increase their productivity and require parts that can withstand the elements rely on aluminum coil to get the job done.

Why might they opt for aluminum coiling over another durable material like steel or copper? At about 33% the density and weight of steel, aluminum renders parts that are much lighter, thereby reducing handling costs and shipping fees. What's more, is the cost is about 50% that of copper.

In fact, according to the Air Conditioning, Heating, Refrigeration News, aluminum versus copper has become "The Great Condensing Coil Debate." In that article published by the industrial news source, while controversy stirs about one versus the other, one thing is clear. Condensing coils made from aluminum have made air conditioning more affordable. "That (aluminum coil) brought the cost of an a/c system down, making it more palatable to consumers and builders."

But the heating, ventilation and air conditioning sector isn't the only industry in which aluminum coil is used. The transportation industry, in fact, is the largest user of the product in the United States, accounting for close to 30% of all that is produced in the nation. Indeed, the average car driven in this country contains over 275 pounds of aluminum, and some luxury car makers use aluminum sheeting to make the entire bodies of their vehicles. Perhaps that's why aluminum has become the most abundantly produced non-iron metal.

In the construction industry, aluminum coil is also being used more and more frequently as trim to cover base materials on homes. Because the aluminum can be anodized with a decorative oxide and comes in a wide variety of colors, it provides a pleasing finishing feature. Best of all, it is easy to install, making it a nice home project for the do it yourselfer. The most typical way in which aluminum coil is put to use in homes is as a trim finish for windows, soffit boarding, siding and roof edging.

Beyond these industrial advantages, aluminum is extremely kind to the environment thanks to its ability to be recycled. That ecological friendliness is further enhanced by aluminum's ability to be recycled an infinite number of times. In the transportation industry alone, that adds up to substantial benefits to the earth. In concrete terms, the average car is made up for about 7% aluminum, yet aluminum amounts to around 40% of the total material scrap value of the average vehicle at the end of its useful life.

101 aluminum sheets are widely acknowledged to have excellent corrosion resistance in saltwater environments. Aluminum possesses inherent resistance to corrosion and when it encounters saltwater, it develops a protective oxide layer on its surface, which enhances its resistance to corrosion. This oxide layer functions as a shield, obstructing direct contact between the saltwater and the underlying metal, thereby decelerating the corrosion process. Nevertheless, it is crucial to acknowledge that prolonged exposure to saltwater can still result in some level of corrosion over time. Employing regular maintenance and applying protective coatings can significantly augment the corrosion resistance of 101 aluminum sheets in saltwater environments.
Indeed, aluminum sheets find utility in electrical applications. Renowned for its exceptional conductivity, aluminum boasts nearly 60% of copper's electrical conductivity. This renders it suitable for diverse electrical applications, ranging from wiring and bus bars to transformers and electrical panels. Owing to their lightweight and resistance to corrosion, aluminum sheets are frequently employed in the fabrication of electrical enclosures and housings. Furthermore, aluminum emerges as a cost-effective alternative to other metals, such as copper, thereby solidifying its reputation as a favored selection in numerous electrical applications.
To prevent distortion during the welding of aluminum sheets, there are several important steps that can be taken: 1. It is crucial to properly prepare the joint by cleaning and beveling the edges of the aluminum sheets. This will ensure a better fit-up and reduce the likelihood of distortion. 2. The use of appropriate fixtures and clamps to hold the aluminum sheets in place during welding can help distribute the heat evenly and prevent movement or buckling. This will minimize the risk of distortion caused by thermal expansion. 3. Tack welding can be done at regular intervals along the joint before performing a full weld. This temporarily secures the sheets and allows for controlled cooling, reducing distortion. 4. Following a proper welding sequence is also beneficial. Starting from the center and gradually moving towards the edges, alternating between sides, helps balance the heat input and allows for cooling between welds, minimizing distortion. 5. Preheating the material before welding can help reduce the temperature gradient and minimize distortion for thicker aluminum sheets. Post-weld heat treatment can also be applied to relieve residual stresses and promote dimensional stability. 6. Employing appropriate welding techniques, such as lowering the heat input and using a slower travel speed, can help minimize distortion. Using a smaller weld bead size and avoiding excessive weaving also control the heat input and reduce distortion. 7. It is crucial to ensure that the welding parameters, such as voltage, current, and wire feed speed, are correctly set and maintained. Using the appropriate parameters for the specific aluminum alloy being welded will result in a more controlled heat input, reducing distortion. By implementing these preventive measures, the risk of distortion during aluminum sheet welding can be significantly reduced, leading to improved weld quality and dimensional stability.

Q:How do i prepare the aluminium sheet to paint with oils on it?Do I have to buy special aluminium or any kind will work?
Any aluminium will do. Sandpaper it 3 times with decreasingly coarse grain papers, clean it thoroughly with turpentine and then apply 3 coats of white oil based paint. Gesso would do too, but you'd have to use more layers
There are several packaging options available for aluminum sheets during transportation. Some common methods include wrapping the sheets in protective film or paper, using wooden crates or pallets to stack and secure the sheets, and using cardboard or plastic edge protectors to prevent damage. Additionally, aluminum sheets can also be packaged in custom-cut foam or bubble wrap for added cushioning and protection during transit.
