Q:my text says aluminium does not corrode much as a passive aluminium oxide layer is formed on it.Well other metals such as sodium adn potassium also form oxides. Why dont their oxides prevent further oxidation ?

Not sure. Maybe because Na K are more active than Aluminum.

Q:Can aluminum coils be used in the construction industry?

The construction industry can indeed utilize aluminum coils. Aluminum, being a versatile and lightweight material, presents several benefits for construction purposes. In construction, aluminum coils find common use in roofing, siding, gutters, and fascia. One of the primary advantages of employing aluminum coils in construction lies in their ability to resist corrosion. Aluminum naturally develops a protective oxide layer on its surface, effectively preventing rust and corrosion. This quality makes it highly suitable for exterior applications, where exposure to moisture and weather elements is prevalent. Furthermore, aluminum coils prove easy to shape and work with, making them excellent for creating custom components and structures. They can be easily cut, bent, and formed into various shapes, allowing for flexibility and creativity in construction projects. Another benefit of aluminum coils is their lightweight nature. Compared to metals like steel, aluminum is significantly lighter, making it easier to handle and transport. This attribute can reduce construction costs and enhance the efficiency of installation processes. Moreover, aluminum is an environmentally-friendly and sustainable material. It is 100% recyclable and can undergo repeated reprocessing without losing its properties. Consequently, aluminum coils make for an eco-friendly choice in construction projects. In conclusion, aluminum coils enjoy extensive use in the construction industry due to their corrosion resistance, flexibility, lightweight nature, and sustainability. They offer numerous advantages for diverse applications, contributing to the overall efficiency and durability of construction projects.

Q:Would an SS scribe scratch an aluminum plate? What is the hardness value of both metals?

SS and aluminium are available in very many shape and sizes SS is very much harder than aluminium aluminium has a hardness of 28 SS 90 to 100 Guru

Q:* How is hitting with a aluminum Wiffle Ball feel and work out?* Did you like the results you had hitting with a aluminum Wiffle Ball bat?

I've used an aluminum Wiffle bat and it really feels a lot better to hit with than the yellow plastic number. The Aluminum bats are still super light, but there is a bit of weight to it, and that weight is kind of end-loaded, which you can really feel as you turn your wrists over. The net result is a swing that feels more like a real bat with the barrel whipping through the hitting zone instead of that flyswatter feel you get with the regular bats. Oh, and you definitely get more distance when you connect. Definitely. I actually played in a Wiffle Ball tournament a few years ago and used those bats. Someone said that they no longer make them or they've been outlawed or something along those lines.

Q:Are aluminum coils suitable for outdoor applications?

Yes, aluminum coils are suitable for outdoor applications. Aluminum is known for its excellent corrosion resistance, making it a popular choice for outdoor use. It is not prone to rust or deterioration when exposed to moisture, sunlight, or harsh weather conditions. Additionally, aluminum coils are lightweight, durable, and have a high strength-to-weight ratio, making them ideal for various outdoor applications such as roofing, gutters, air conditioning systems, and outdoor furniture. Moreover, aluminum is a highly recyclable material, making it an environmentally-friendly choice for outdoor projects. Overall, aluminum coils are a reliable and practical option for outdoor applications.

Q:Can aluminum coils be used for signage and display applications?

Yes, aluminum coils can be used for signage and display applications. Aluminum is a versatile material that is lightweight, durable, and resistant to corrosion, making it an ideal choice for various signage and display purposes. Its flexibility allows for easy shaping and customization, while its smooth surface provides a perfect canvas for printing graphics and designs. Additionally, aluminum coils can be easily mounted, making them suitable for both indoor and outdoor signage and displays.

Q:What happened to the aluminum coil coming out of the annealing furnace?

There is oil on the aluminum coil and the annealing time is too long.

Q:What is the weight of aluminum coils per square foot?

The weight of aluminum coils per square foot can vary depending on the thickness of the coil. On average, aluminum coils weigh around 0.5 pounds per square foot. However, it is important to note that this is an approximate figure and may vary slightly depending on the specific alloy and manufacturing process used. It is always recommended to consult the manufacturer or supplier for the exact weight specifications of the aluminum coils you are working with.

Q:Can aluminum coils be used for electrical transformers?

Yes, aluminum coils can be used for electrical transformers. Aluminum is a suitable material for transformer coils due to its high electrical conductivity and lower cost compared to copper. While copper has traditionally been the preferred choice for transformer windings, the use of aluminum has gained popularity in recent years due to its lighter weight and lower price. Aluminum coils are also advantageous in terms of thermal conductivity, as they dissipate heat more efficiently than copper. However, it is important to consider the specific requirements and design considerations of the transformer, as the choice between aluminum and copper coils may depend on factors such as voltage, current, size, and insulation requirements.

Q:what is aircraft grade aluminum?

Aluminum is never used in it's pure form. It is always used as an alloy - in combination with other metals and substances. The phrase aircraft grade aluminum is a bit misleading because there are a large number of different grades of aluminum used on aircraft - some of them aren't very special at all, but some of the grades are highly specialized, down to the micro-structure of the metal. Different grades of aluminum contain different quantities of other substances may have been forged or wrought in different types of processes. Typically high performance military aircraft will utilize very grade materials. The common characteristics of high grade aluminum alloys are it's ability to withstand heat and fracturing they are also extremely light. When people advertise products like keys made from aircraft grade aluminum it makes me laugh - because it's most likely to be the same grade aluminum they use to make tray stands, certainly not the same grade they use for structural components! Hope this helps!
