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:I have been trying to make some thermite for a while now, and I haven't had much success. I have tried using iron oxide and that didn't work. then I tried using manganese dioxide, also without success. I'm pretty sure I have the right proportions for each of the corresponding oxides, but it just isn't working. I am using magnesium ribbon to light it.The aluminum I am using is the byproduct of me trying to cut a block of aluminum with a hacksaw (best way I have available to cut it) and there is a lot of aluminum powder that is being made. But i'm not sure if it is fine enough to be effective. I don't have an etch-a -sketch so that's not an option. I know that it has to be fairly fine grained, but how small do the particles need to be?FOR EVERYONE WHO IS GOING TO TRY AND TELL ME THAT MAKING THERMITE IS DANGEROUS OR SOMETHING ALONG THOSE LINES......DONT!!!!!!!!.......... IM NOT GOING TO LISTEN SO SAVE YOURSELF THE TYPING AND ME THE READING
- In 35+ years of demonstrating the thermite reaction, I have used fine aluminium powder to quite visible small bits. The proportions don't seem too critical, but try and keep near the amounts represented by the balanced eqtn. The difficult bit is getting the wretched stuff to ignite. With some mixes several strands of magnesium ribbon as fuse still wouldn't get it to ignite. I found a pile of 'ignition powder' at the base of the Mg often helped. There was a good commercial one available in the UK but I often made one up, main ingredients barium peroxide and magnesium powder, about 50/50. Needless to say, ignite with this mix where you won't breathe any nasty fumes. To get a good result, if I didn't use a proper crucible, I shaped one of Al foil about the capacity of 2-3 eggcups. This was put on sand in a big coffee tin, then more sand added to fill round the sides. This would give a good amount of iron. I once made the mistake of rushing in too quickly to get out the red hot iron.... and completely melted the ends of a large pair of Nickel tongs!
- Q:What is the mass of 3.45 moles of Aluminum sulfate?Can u explain how?
- Aluminum sulfate is Al2S3, so you got two atoms of aluminum and three of oxygen. Hence the molar mass of aluminum sulfate is: 2X16 (two times molar mass of oxygen) + 3X32 (three times molar mass of sulfur). Keep in mind that the molar mass of an elements equals its mass number. We have 128 grams per mole or 128 pounds per lb-mol. Since you have 3.45 moles of Al2S3 you just have to do 3.45 times 128 = 441.6 grams
- Q:Can aluminum coils be welded or joined?
- Aluminum coils have the capability to be welded or joined. Aluminum, being a highly weldable metal, can be easily joined through the utilization of different welding techniques. TIG welding, MIG welding, and resistance welding are the most commonly employed methods for welding aluminum coils. TIG welding is a precise and adaptable technique that employs a non-consumable tungsten electrode to generate the arc. This method is extensively utilized in welding aluminum coils due to its ability to offer exceptional control over the welding process, resulting in welds of high quality and strength. On the other hand, MIG welding employs a consumable wire electrode and a shielding gas to safeguard the weld zone from atmospheric contamination. This technique is faster compared to TIG welding and is often favored for larger production runs. Resistance welding is yet another prevalent method employed for joining aluminum coils. It involves the passage of an electric current through the overlapping metal surfaces to generate heat and pressure, thereby creating a robust weld joint. This technique is commonly used in industries that require high-speed production. It is important to note that welding aluminum coils necessitates specific techniques and considerations due to the distinctive properties of the metal. Aluminum possesses a lower melting point and higher thermal conductivity than other metals, which can make the welding process more challenging. Proper cleaning, preheating, and the selection of suitable filler materials are crucial in achieving successful welds. To summarize, aluminum coils can be welded or joined using various techniques such as TIG welding, MIG welding, and resistance welding. However, it is imperative to adhere to proper procedures and take into account the specific properties of aluminum to ensure the creation of strong and dependable welds.

This will ensure proper airflow and prevent the coils from overworking, which can lead to inefficiency and potential damage. In conclusion, the maintenance requirements for aluminum coils involve regular cleaning, inspection for damage, corrosion, or leakage, and maintaining a clear and clean surrounding area for optimal performance and longevity. Following these maintenance practices will help ensure the efficient functioning of the aluminum coils and extend their lifespan.
- Q:I had a physics exams today and it was asking whether or not a shiny surface aluminium blanket was suitable to keep the sleeper warm. I put that because it's a conductor of electricitiy, heat loss will be greater so it wont be suitable for keeping him warm. On the other hand, some other people said that because it had a shiny surface, thus a good reflector of heat, it would be suitable for keeping him warm. Are both arguments correct?
- it will only keep you warm if you're in the sun. if you're in the dark then you're whistling Dixie Allan, you taught me something new, thank you :)

- Yes, aluminum coils can be used for roofing. Aluminum is a popular and commonly used material for roofing due to its durability, lightweight nature, and resistance to corrosion. It is often chosen for its ability to withstand harsh weather conditions and its long lifespan, making it a suitable option for various roofing applications.
- Q:Can aluminum coils be used in electrical cables?
- Electrical cables can indeed incorporate aluminum coils. Aluminum is widely utilized as a material for electrical conductors due to its exceptional electrical conductivity and comparatively lower cost when compared to copper. Its usage is particularly prominent in power transmission and distribution cables that necessitate long-distance transmission. Overhead power lines and underground cables often employ aluminum coils. However, it is crucial to acknowledge that aluminum possesses a lower tensile strength than copper, requiring careful design and manufacturing of the cables to ensure sufficient mechanical strength. Furthermore, achieving the same electrical performance with aluminum conductors necessitates larger cross-sectional areas compared to copper, potentially resulting in slightly larger cable sizes.
- Q:How are aluminum coils tested for dimensional accuracy?
- Aluminum coils are tested for dimensional accuracy through various methods to ensure that they meet the required specifications. One common method is the use of specialized equipment such as calipers, micrometers, and digital measuring devices. These tools are used to measure the dimensions of the coils, including their width, thickness, and length, with high precision. During the testing process, a sample coil is selected and measured at different points along its length to check for any variations or deviations from the specified dimensions. This helps to identify any potential issues with the coil's dimensional accuracy. In addition to manual measurements, advanced technologies such as laser scanning systems and optical sensors are also utilized. These technologies provide non-contact measurements, allowing for faster and more accurate assessments of the coil's dimensions. Laser scanners create a digital representation of the coil's surface, which can be compared to the desired specifications to determine if any deviations exist. Furthermore, computerized systems are employed to analyze the collected data and generate detailed reports. These reports provide comprehensive information regarding the coil's dimensional accuracy, highlighting any discrepancies from the required standards. This data analysis enables manufacturers to identify and address any potential problems promptly. Overall, aluminum coils undergo stringent testing procedures to ensure their dimensional accuracy. The combination of manual measurements, advanced technologies, and computerized analysis provides a thorough assessment of the coils' dimensions, allowing manufacturers to maintain high-quality standards and deliver products that meet the precise specifications demanded by various industries.
- Q:What is the typical fatigue strength of aluminum coils?
- The fatigue strength of aluminum coils can vary depending on several factors, such as the alloy composition, heat treatment, manufacturing process, and the specific application. However, compared to other metals like steel, aluminum is generally known to have relatively low fatigue strength. Typically, the fatigue strength of aluminum coils falls within the range of 30% to 50% of their ultimate tensile strength (UTS). This means that the fatigue limit or endurance limit of aluminum coils is usually less than half of their maximum strength. It is worth noting that factors such as surface defects, stress concentrations, and environmental conditions like temperature and humidity can also affect the fatigue strength of aluminum coils. These factors can further decrease the fatigue strength of aluminum coils. Hence, when designing and using aluminum coils in applications where fatigue is a concern, it is crucial to consider the specific alloy and processing conditions. Additionally, implementing suitable design practices and maintenance procedures is vital to mitigate the risk of fatigue failure.
