Non-corrosive:
Even in industrial environments where other metals are frequently corroded, aluminum is extremely resistant to weathering and corrosion. Several acids won't cause it to corrode. Aluminum naturally generates a thin but effective oxide layer that inhibits further oxidation, giving it exceptional corrosion resistance. As a result, objects made from aluminum oxide are nearly impermeable to many corrosive substances.
Easily machined and cast:
Since it melts more readily than steel, aluminum coil is more pliable and simpler to pour into molds. Aluminum castings are also less stiff than steel, making them easier to work with while steel castings need a lot more effort. It is one of the most machinable metals available, making processing time cost-effective.
Lightweight yet durable:
Aluminum coil is lightweight and portable since it has a low density. This makes it the chosen metal for use in the construction of airplanes. It may be considered as being even more durable since it can be recycled.
Non-magnetic and non-sparking:
Aluminum is non-magnetic because of its crystalline structure. An oxide layer is quickly formed after any scratch making it non-sparking.
Good thermal and electrical conductor:
Free electrons in the structure of Aluminum Coils make it a good electrical conductor. Since there is a steady flow of these electrons, the aluminum coil is therefore a good conductor of heat.
Soft:
Aluminum coils are soft because of the available free electrons for bonding.
Non-toxic:
Exposure to aluminum is not harmful to the body.
Malleable:
Since aluminum is more pliable than the majority of other metals, shaping the coils is simpler. Because of the increased flexibility, engineers may bend coils into effective designs. For instance, microchannel coils improve heat transfer, decrease leaks, and have higher corrosion resistance.
Ductile:
Aluminum has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking. It is the second most malleable metal and is highly ductile for use in transforming this material into wire.
Aluminum coils frequently come in sizes with internal diameters of 508 mm, 406 mm, and 610 mm. The coil's outer diameter is defined as the diameter created by its outer, circular contour. The capacity and geometrical features of the recoiler machine being used to process the aluminum coil typically determine its dimension. The space between the aluminum coil's two adjacent surfaces measured perpendicularly refers to how thick the coil is. Engineers must consider the coating material's dimensions for the aluminum coil because a difference of just 0.06 mm can substantially impact the precision of design calculations. The coil width is the aluminum coil's transverse dimension.
For coils of aluminum, the weight of an aluminum coil is calculated as (Coil Diameter*1/2*3.142 - Inner Diameter*1/2*3.142)*Coil Width*2.7(Density of Aluminium)
This formula only provides a rough estimate of the weight of an aluminum coil roll because different alloys have varied densities and measurement mistakes always exist for diameters. In addition, the manufacturer's feeding frame capacity affects the weight of the aluminum coil.
The thickness of an aluminum coil might be anywhere from 0.2 to 8mm. Most rolls of aluminum, however, are between 0.2mm and 2mm thick. These various thicknesses determine the specific use of aluminum coil. Consider an insulation aluminum coil, where 0.75mm is the most common thickness. The coated aluminum roof coil, which is equally popular, is only 0.6 to 1.0mm thick. Only the special-purpose aluminum rolls are thicker. Of course, customers are free to request any thickness less than 8mm from the provider based on their specific requirements.
