Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).



Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Q: Are aluminum sheets suitable for HVAC ductwork?
Indeed, HVAC ductwork can be made using aluminum sheets. The lightweight and durable characteristics of aluminum make it a favored option for ductwork. Its resistance to corrosion is crucial in HVAC systems where moisture and condensation are prevalent. Moreover, aluminum ductwork exhibits excellent thermal conductivity, enabling efficient heat transfer. Furthermore, the simplicity of working with aluminum sheets renders installation and maintenance relatively easy. Ultimately, aluminum sheets guarantee dependable performance and energy efficiency, making them a trustworthy selection for HVAC ductwork.
Q: How do aluminum sheets perform in extreme temperatures?
Aluminum sheets are known for their excellent performance in extreme temperatures. Aluminum has a high melting point, around 660 degrees Celsius, which makes it capable of withstanding high temperatures without deforming or melting. In extreme heat, aluminum sheets have a low thermal expansion rate, meaning they will not expand or contract significantly, ensuring dimensional stability. This makes them ideal for applications in industries such as aerospace, automotive, and construction, where extreme temperatures are common. Similarly, in extremely cold temperatures, aluminum sheets retain their strength and durability, unlike some other metals that become brittle and prone to cracking. Additionally, aluminum has excellent thermal conductivity, allowing it to distribute heat evenly, which is beneficial in applications where heat dissipation is crucial. Overall, aluminum sheets perform exceptionally well in extreme temperatures, making them a reliable choice for various industries.
Q: For a high school Chemistry course I made soap for a project. Before doing this, thank god, i learned that one should never use an aluminum container to mix the lye (NaOH) and water. Now, I need to know why. I know it eats away at the container but i can't figure out why. It goes against everything I've learned so far. At first i thought it was because Aluminum was, for some strange reason :o, more reactive than Sodium therefore replacing it in the reaction but that turned out not to be true. Does anyone have an idea of why? Thanks
Under normal circumstances, aluminum does not react with water, as an impermeable protective layer composed of aluminum hydroxide either forms within seconds or is already in place. With the addition of sodium hydroxide, the formation of a protective layer is prevented. With the production of aluminates [ Al(OH)4 ]-, the amphoteric (capable of acting as either an acid or a base) aluminum hydroxide Al(OH)3 goes in solution: 2 Al + 6 H2O -- 2 Al(OH)3 + 3 H2 Al(OH)3 + NaOH -- Na+ + [ Al(OH)4 ]- A layer of aluminum oxide previously formed by passive corrosion is dissolved by the addition of sodium hydroxide. For this reason, the reaction takes place at the beginning relatively slowly: Al2O3 + 2 NaOH + 3 H2O -- 2 Na+ + 2 [ Al(OH)4 ]- The aluminum completely dissolves and the water acts here too as an acid (for an analog, see Experiment 4.4.1). This reaction is used in drain cleaners. They are mostly made out of strong alkalis, to which alumunim or zinc has been added. The alkalis break down organic residues chemically. In addition, the formation of hydrogen leads to a bubbling effect which adds an additional mechanical cleaning mechanism. The big problem here is the formation of hydrogen gas (as well as some heat). The hydrogen gas is flammable, and if it's in a closed container, will explode
Q: I'm trying a new brownie recipe for the holidays this year. My experiences with baking brownies is never good. After I've taken them out of the oven and let them cool, I can never get them out of the pan without them falling apart on me! Can I bake brownies in the pan if it's lined with aluminum foil? I think that may make them easier to get out. Also, the new recipe I'm trying is actually a cheater recipe that starts with devils food cake mix. These are going to be gifts for friends and coworkers, and I just want perfectly squared, clean brownies! Any tips or ideas?
You can do that with the foil and when the brownies are removed from the pan you will have saved yourself a clean up. Just throw out the foil. You can also spray the pan with PAM and then you will have to clean the pan afterwards.
Q: How do aluminum sheets compare to other metals?
Aluminum sheets have several advantages when compared to other metals. Firstly, aluminum is very light in weight, making it an ideal choice for applications where weight is a concern, such as in the aerospace industry. Additionally, aluminum is highly resistant to corrosion, which means it can withstand exposure to moisture and chemicals without deteriorating. This makes aluminum sheets suitable for outdoor use and in environments with high humidity or corrosive substances. Moreover, aluminum has excellent conductivity, both thermal and electrical. This makes it a popular choice for heat sinks, electrical enclosures, and other applications that require efficient heat dissipation or electrical conduction. Furthermore, aluminum sheets can be easily shaped and formed, giving them versatility in various manufacturing processes. They can be bent, cut, welded, and machined with relative ease, making them highly adaptable to different design specifications. In terms of cost, aluminum is generally more affordable compared to other metals like steel or copper. This makes it a cost-effective option for many industries, especially for large-scale production or projects with budget constraints. However, it is important to note that aluminum sheets may not be suitable for applications that require high strength or extreme temperatures, as aluminum has lower strength and melting point compared to certain other metals. In such cases, metals like steel or titanium may be more appropriate. In summary, aluminum sheets offer a combination of lightweight, corrosion resistance, good conductivity, versatility, and affordability that makes them a preferred choice in many industries. However, the specific requirements of a project or application should be considered to determine if aluminum sheets are the best fit or if another metal would be more suitable.
Q: doesn't particularly need to be welding but i need to make an air tight permanent seal around 2 very thin sheets of aluminium (like .02 inches thick) i was thinking .02 inch 5052 aluminum because its the thinnest i can find but am obviously up for suggestions.
GOOP silicone adhesives are much harder when set than 100% silicone adhesives more commonly seen, but if you are just butting the tubes, epoxy to build a gusset would be a better choice. Always clean all surfaces with soap and water and then with denatured or high percent rubbing (isopropal) alcohol to improve bonding.
Q: Are aluminum sheets suitable for thermal insulation?
No, aluminum sheets are not suitable for thermal insulation on their own. While aluminum is a good conductor of heat and electricity, it does not have good insulating properties. In fact, aluminum sheets can actually transfer heat instead of blocking it, making them ineffective for thermal insulation purposes. For proper thermal insulation, materials with low thermal conductivity, such as fiberglass, mineral wool, or foam boards, are commonly used. These materials are designed to trap air or create a barrier that reduces the transfer of heat, ensuring effective insulation.
Q: This question asks for a list of various types of aluminum profiles that are typically used in conjunction with aluminum sheets.
<p>Aluminum profiles are extruded shapes commonly used with aluminum sheets for various applications. The different types include: 1. Angle profiles, which are used for corners and edges. 2. Channel profiles, suitable for creating channels or frames. 3. T-slot profiles, ideal for modular systems requiring adjustable components. 4. U-channel profiles, used for covering edges and creating frames. 5. H-profiles, often used in structural applications. 6. Flat bar profiles, used for simple straight edges. 7. Round and square tube profiles, used for structural support and design elements. 8. Special profiles, which are custom-made for specific applications. These profiles are chosen based on the structural needs and design requirements of the project.</p>
Q: What are the different types of aluminum sheets?
There exists a variety of aluminum sheets, each possessing distinct characteristics and applications. Here are some commonly encountered types: 1. The plain aluminum sheet, with its smooth surface and uniform thickness, serves as the fundamental option. It holds widespread usage across various industries for general purposes. 2. The embossed aluminum sheet, achieved by rolling the metal through a patterned roller, presents a textured or patterned surface. It finds common application in fields like interior design or automotive trim, where decorative purposes are desired. 3. The perforated aluminum sheet, as its name implies, contains small holes or perforations throughout its surface. It frequently finds application in architectural scenarios, such as building facades or sunscreens, as well as in filtration systems. 4. The treadplate aluminum sheet, also known as checker plate or diamond plate, exhibits a raised pattern of lines or diamonds on its surface. This pattern enhances traction, making it suitable for industrial flooring or stair treads, where slip resistance is vital. 5. The anodized aluminum sheet undergoes an electrochemical process, forming a protective oxide layer on the surface. This process enhances durability, corrosion resistance, and allows for color customization through dye acceptance. Architectural applications, signage, and consumer products commonly employ anodized aluminum sheets. 6. The painted aluminum sheet, coated with a layer of paint, not only enhances appearance but also provides added corrosion protection. It is often utilized in applications where aesthetics are paramount, such as building facades, signage, or automotive parts. These examples represent a small selection of the aluminum sheet types available in the market. The selection of an appropriate type depends on specific project requirements, encompassing factors like durability, appearance, corrosion resistance, or slip resistance.
Q: Yesterday I picked up an 1988 performance bike. I bought it for the parts. It rode really good and now I'm deciding to keep it as is but I'm wondering if the bike is safe to ride. I've hear of aluminum horror stories and I'm assuming old aluminum isn't asnymore safe.Should I toss the frame and put the parts on a steel frame I have or ride it and not worry about it failing.
1988? Why do you believe it is aluminum? So far as I can recall, Performance didn't begin offering bicycles AT ALL until about 1992. Even then they had steel frames... their bikes were supplied by a Taiwanese company by the name of UEC who also made (and makes) KHS brand bikes. Regarding early aluminum failures, yes, there were many simply because factories were unfamiliar with the material and thought they could get away without the post treatment that a welded aluminum structure often requires. Another reason for aluminum frame failure was when a few factories attempted to bond aluminum tubes to lugs. This is also a problem with carbon fiber bikes. This is because the epoxy used degasses, or hardens and becomes crystallized. The now brittle epoxy cracks and results in catastrophic failure. This, in the factory's opinion, was not a warranty event. I'll tell you what. Grab a magnet off of your refrigerator and see if it sticks to the frame. if it does- even a tiny bit- then it is steel. If the frame is WELDED aluminum it should be retired since there is no way of telling whether the frame was properly post-treated. If the frame is BONDED then it should be retired because of the possibility of the epoxy fracturing.
