FAQ

The thickness of an aluminum coil can differ depending on its intended purpose and use. Generally, aluminum coils can have a thickness ranging from 0.006 inches (0.15 mm) to 0.25 inches (6.35 mm). Thinner coils are frequently utilized for lightweight applications like packaging materials, whereas thicker coils are commonly found in industries such as construction, automotive, and aerospace, where strength and durability are crucial. It is worth mentioning that the precise thickness requirements may vary depending on the unique needs and specifications of the project or product being manufactured.

what properties etc makes us use aluminium as the material behind cans...And why does it have the properties?

Aluminium only became popular in the sixties. Prior to that it was steel cans. You had to have a church key to open them. Aluminium is cheaper to recycle and make than steel. It always comes down to money and costs.

Yes, there are limitations to the maximum coil diameter of aluminum coils. The maximum coil diameter is determined by several factors including the type and thickness of the aluminum, the equipment used for coiling, and the intended application of the coil. Generally, larger coil diameters can be achieved with thinner and more ductile aluminum alloys. However, as the coil diameter increases, it becomes more challenging to maintain the structural integrity of the coil and prevent deformation, wrinkling, or damage during handling and transportation. Additionally, the equipment used for coiling may have limitations in terms of the maximum diameter it can handle. Therefore, it is important to consider these factors when determining the maximum coil diameter for aluminum coils.

im doing an a level physics presentation on aluminium and im trying to compare aluminium and copper in electricity pylons.i know that copper will have a better conductance than aluminium becasue it has a lower resitivity but i need to come up with a calculation to prove why aluminium is better for use in electricity pylons? i know its down to aluminium being more lightweight than copper and also much cheaper. But im not sure how to create an calculation to show this?:) any help is greatly appreciated

Copper has lower resistance per unit volume, ie, a 1 cm diameter copper wire has less resistance than a 1 cm aluminum wire. BUT, aluminum is much lighter than Cu for the same diameter. If you used an aluminum wire that weighs the same as the 1 cm diameter copper wire, it would have LOWER resistance. And that is why aluminum is used in power transmission, and also in aircraft, where weight is important. to do this you calculate density resistivity which is (resistivity x density). Here is a partial table: Al 28.2e-9 Ω-m * 2700 kg/m? = 76e-6 Ω-kg/m? Cu 17.2e-9 Ω-m * 8960 kg/m? = 154e-6 Ω-kg/m? Ag 15.9e-9 Ω-m * 10500 kg/m? = 167e-6 Ω-kg/m? Au 22.14e-9 Ω-m * 19300 kg/m? = 427e-6 Ω-kg/m? Zn 68e-9 Ω-m * 7130 kg/m? = 485-6 Ω-kg/m? Fe 100e-9 Ω-m * 7870 kg/m? = 787e-6 Ω-kg/m? Note that Al is half that of Cu.

Certifications and standards exist for aluminum coils, ensuring their quality and performance. The Aluminum Association's Certification Program is widely recognized as the most prominent certification for aluminum coils. This program guarantees that the coils meet the specific standards and requirements established by the association. Moreover, multiple organizations such as ASTM International, ASME, and ISO have set various standards and specifications governing the manufacturing and performance of aluminum coils. These standards encompass crucial aspects like the coils' chemical composition, mechanical properties, and dimensional tolerances, guaranteeing compliance with industry requirements.

On Square-D service panels, are the main lugs rated for aluminum wire? Or do I need to use an anti-oxidant compound? What about on Milbank outdoor meter bases?

No you do not have to use any type compound on it.

To ensure the production of high-quality and defect-free aluminum coils, a variety of methods are employed to inspect for surface defects. Visual inspection is one commonly used technique, wherein trained inspectors carefully examine the entire surface of the coils for imperfections such as scratches, dents, or unevenness. This inspection takes place in optimal lighting conditions to ensure visibility and accuracy. In addition to visual inspection, more advanced techniques are utilized to detect subtle surface defects. An example of such a method is fluorescent penetrant inspection, where a fluorescent dye is applied to the coil surface. This dye seeps into any surface defects or cracks, and after a certain period of time, the excess dye is removed. The coil is then examined under ultraviolet light, which causes the dye to fluoresce, thereby making any defects easily visible. Another frequently used technique is eddy current testing, a non-destructive method that employs electromagnetic induction to identify defects like cracks or delaminations on the surface of aluminum coils. A probe is passed over the coil surface, and any variations in electrical conductivity caused by defects are detected and analyzed. Furthermore, automated systems equipped with high-resolution cameras and image-processing software can also be utilized for surface inspection. These systems capture detailed images of the coil surface, which are then analyzed by the software based on predefined criteria to identify any defects. This method ensures consistent and objective inspection results. Overall, thorough inspection procedures are implemented to detect and address any surface defects in aluminum coils before further processing or usage. These inspections are vital in maintaining product quality, adhering to industry standards, and ensuring customer satisfaction.

Aluminum coils play a crucial role in the production of automotive parts. Due to their lightweight and corrosion-resistant properties, aluminum coils are extensively used in the manufacturing of various automotive components. One of the main applications of aluminum coils in the automotive industry is in the production of body panels. These coils are processed into sheets, which are then formed and shaped into body panels such as hoods, doors, fenders, and roofs. The lightweight nature of aluminum helps to reduce the overall weight of the vehicle, resulting in improved fuel efficiency and better handling. Aluminum coils are also used in the production of heat exchangers for automotive air conditioning systems and radiators. The excellent thermal conductivity of aluminum allows for efficient heat transfer, ensuring optimal cooling performance. This helps to maintain the desired temperature in the vehicle's interior and prevent engine overheating. Additionally, aluminum coils are utilized in the production of various engine components. They are widely used in the manufacturing of cylinder heads, engine blocks, and intake manifolds. The high strength-to-weight ratio of aluminum makes it an ideal material for these applications, as it provides strength and durability while reducing the overall weight of the engine. Moreover, aluminum coils are used in the production of suspension components such as control arms and subframes. The lightweight nature of aluminum allows for better suspension performance, resulting in improved handling and a smoother ride. In summary, aluminum coils are extensively used in the production of automotive parts due to their lightweight, corrosion-resistant, and high-strength properties. They are employed in the manufacturing of body panels, heat exchangers, engine components, and suspension parts, contributing to the overall performance, efficiency, and durability of vehicles.
