Q:Can aluminum foil coil be stores for a long time?

It is ok within one or two years, but for five or six years, it will be oxidized.

Q:Are aluminum coils resistant to vibration?

Yes, aluminum coils are generally resistant to vibration. Due to their inherent strength and elasticity, aluminum coils can withstand vibrations and oscillations without significant deformation or damage. This property makes them suitable for various applications that involve mechanical movement or exposure to vibrations.

Q:How are aluminum coils used in the production of gutters and downspouts?

Aluminum coils are used in the production of gutters and downspouts by being formed and shaped into the desired gutter or downspout profile. The coils are typically fed through a roll-forming machine that bends and molds the aluminum into the specific shape and size required. This process allows for the production of seamless gutters and downspouts, providing a more efficient and aesthetically pleasing solution for drainage systems.

Q:Will the aluminum braking surface dissipate heat evenly allowing for fast stops from fast descents or will I have to still pulsate braking to reduce heat build up in the tires and tubes?

Aluminum is tried and true, basalt seems like a gimmick. Aluminum's light, it's sought after over steel, which is cheaper and heavier and stronger. No basalt, no need.

Q:Are aluminum coils more expensive than other coil materials?

It depends on the specific material being compared. Generally, aluminum coils tend to be more expensive than some other coil materials, such as copper or steel. However, the cost can vary depending on factors like the coil size, thickness, and supplier.

Q:How are aluminum coils tested for quality and performance?

Aluminum coils are tested for quality and performance through a series of rigorous inspection processes. These tests aim to assess the mechanical, chemical, and physical properties of the coils to ensure they meet the required standards. One common test conducted is the visual inspection, where trained technicians examine the surface of the aluminum coils for any visible defects such as scratches, dents, or irregularities in shape. This step is crucial as it helps identify any cosmetic flaws that may affect the overall performance and quality of the coils. Another important test is the dimensional inspection, which involves measuring the thickness, width, and length of the coils to ensure they meet the specified tolerances. This test is critical as it helps guarantee the coils will fit properly in their intended applications and perform optimally. To assess the mechanical properties, various mechanical tests are conducted. One such test is the tensile strength test, which measures the maximum amount of stress a coil can withstand before breaking. This test helps determine the strength and durability of the coils under different operating conditions. Additionally, the hardness test is performed to evaluate the resistance of the coils to indentation or scratching. This test provides insights into the coil's ability to withstand wear and tear, ensuring its longevity. Chemical analysis is another vital aspect of quality testing. The chemical composition of the aluminum coils is examined to ensure it meets the required standards and does not contain any impurities or elements that may compromise the performance or safety of the coils. Furthermore, to assess the thermal properties of the coils, thermal conductivity tests are conducted. These tests measure the coil's ability to conduct heat efficiently, ensuring that it can effectively dissipate heat in applications where it is used. In addition to these tests, other performance evaluations may be conducted depending on the specific application of the aluminum coils. This could include corrosion resistance tests, fatigue tests, or even electrical conductivity tests. These evaluations help determine the coil's ability to perform under different conditions and ensure its reliability and longevity. By subjecting aluminum coils to these comprehensive quality and performance tests, manufacturers can ensure that only the highest quality coils are delivered to customers, meeting their expectations and standards.

Q:if the resistivity of aluminium is 2.7×10-8 Ωm

Let ρ be the resistivity of the aluminum cable, A the cross sectional area of the cable and l the cable's length. The resistance R of the aluminum cable is now given by: R = ρ·l / A = 2.7·10^-8·(10·10^3) / (π·r?) = 2.7·10^-8·(10·10^3) / (π·(1·10^-3)?) = 85.9 Ω I guess the tricky part is remembering: R = ρ·l / A but when you realize how intuitive this equation is you don't have to memorize it. The resistance R is proportional to the resistivity ρ, so we must have the following in our equation: R = ρ·k , where k is some value governed by the dimensions of the cable! It is logical that the resistance is also proportional to the wires length l. This is logical when you realize that the longer the wire the more obstacles the electrons will have to pass by! Now we have that: R = ρ·l·c , where c is another value governed now by the cross sectional area (only dimensional property left). If we think of the wire as a highway with cars instead of electrons we realize that there is less resistance (higher speed) when the highway has many lanes and is very broad. From this we realize that the greater the cross sectional area the smaller the resistance. R must therefore be inversely proportional to A. We now have: R = ρ·l / A I hope there are no mistakes here :P

Q:What is an aluminum coil and what is it used for?

An aluminum coil is a long, thin, and flat strip of aluminum that is typically rolled up. It is used in various industries, including construction, automotive, and electrical, due to its excellent properties such as lightweight, corrosion resistance, and conductivity. Aluminum coils are commonly used for manufacturing various products like roofing, gutters, cans, heat exchangers, and electrical wiring, among others.
