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: How does the grain structure of aluminum sheet affect its properties?
The grain structure of aluminum sheet plays a significant role in determining its properties. The grain structure refers to the arrangement of individual aluminum crystals, also known as grains, within the sheet. The size, shape, and orientation of these grains can influence various mechanical and physical properties of the aluminum sheet. For instance, the grain structure affects the sheet's strength, ductility, hardness, and even its corrosion resistance. In terms of strength, a fine-grained aluminum sheet tends to have higher strength than a coarse-grained one. This is because the presence of smaller grains allows for more grain boundaries, which act as obstacles to dislocation movement and enhance the material's resistance to deformation. On the other hand, a coarse-grained structure has fewer grain boundaries, leading to reduced strength. Furthermore, the grain structure affects the sheet's ductility, which refers to its ability to deform without fracturing. Aluminum sheets with finer grains typically exhibit better ductility as the numerous grain boundaries hinder dislocation motion and prevent crack propagation. In contrast, coarser grains tend to promote crack propagation, resulting in reduced ductility. The hardness of aluminum sheet is also influenced by its grain structure. Generally, a fine-grained structure contributes to higher hardness due to increased dislocation density and grain boundary strengthening. Conversely, a coarse-grained structure leads to reduced hardness as there are fewer obstacles to dislocation motion. Moreover, the grain structure affects the sheet's corrosion resistance. Fine-grained aluminum sheets tend to have improved corrosion resistance compared to coarse-grained ones. This is because the presence of more grain boundaries in fine-grained structures impedes the movement of corrosive agents, thus reducing the likelihood of corrosion. In summary, the grain structure of aluminum sheet significantly impacts its properties. Fine-grained structures generally enhance strength, ductility, hardness, and corrosion resistance, while coarse-grained structures tend to have the opposite effects. Therefore, controlling and optimizing the grain structure during the manufacturing process is crucial in achieving the desired properties of aluminum sheet for various applications.

The resulting etched or engraved design on the aluminum sheet can be further enhanced by adding color or other finishes to create a desired look.
Q: How do you determine the thickness tolerance of an aluminum sheet?
To determine the thickness tolerance of an aluminum sheet, several factors need to be considered. Firstly, it is important to refer to the industry standards and specifications for aluminum sheets. These standards typically provide guidelines and tolerances for various thicknesses of aluminum sheets, which can vary depending on the specific alloy and grade of the material. Next, it is crucial to use precise measuring equipment such as calipers or micrometers to accurately measure the thickness of the aluminum sheet. Multiple measurements should be taken at different locations on the sheet to account for any potential variations. Once the measurements are obtained, they should be compared to the specified thickness tolerance provided by the industry standards. The tolerance typically represents the acceptable range within which the actual thickness of the sheet can vary. For instance, if the specified thickness tolerance is ±0.002 inches, it means that the sheet's thickness can vary within this range. If the measured thickness falls within the specified tolerance range, the sheet is considered to be within tolerance. However, if the measured thickness exceeds the upper or lower limit of the tolerance range, it indicates that the sheet is out of tolerance and may not meet the required specifications. In some cases, it may be necessary to consult with the manufacturer or supplier of the aluminum sheet to determine the specific tolerance requirements for a particular application. They can provide additional information and guidance regarding the appropriate thickness tolerance to ensure the sheet meets the intended purpose. Overall, determining the thickness tolerance of an aluminum sheet involves following industry standards, using accurate measuring equipment, and comparing the measured thickness to the specified tolerance range. This helps ensure that the sheet meets the required specifications and can be used effectively in various applications.
Q: How do you clean aluminum sheets?
To clean aluminum sheets, you can start by rinsing them with water to remove any loose dirt or debris. Then, create a mixture of mild dish soap and warm water. Use a soft cloth or sponge to gently scrub the aluminum sheets with the soapy solution. Avoid using abrasive cleaners or scrub brushes, as they can scratch the surface of the sheets. Once you've thoroughly cleaned the sheets, rinse them again with water and dry them with a clean towel or cloth.
