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:What are the properties of anodized aluminum sheets?
Anodized aluminum sheets are highly desirable for a variety of applications due to their distinct properties. Firstly, they possess a protective oxide layer on their surface, which enhances their resistance to corrosion. This layer is formed through an electrochemical process called anodization, wherein the aluminum sheet is treated with an electric current in an acid electrolyte solution. Consequently, anodized aluminum sheets become more durable and capable of withstanding harsh environments, making them suitable for outdoor use. Another notable property of anodized aluminum sheets is their improved scratch resistance. Through the anodization process, not only is a protective layer created, but the surface of the aluminum also becomes hardened, rendering it more resistant to scratches and wear. This property proves particularly advantageous in applications where frequent handling or abrasive conditions are involved. Moreover, anodized aluminum sheets can be manufactured in a wide range of colors. The anodization process enables the integration of dyes or pigments into the oxide layer, resulting in an array of vibrant color options. This aspect makes anodized aluminum sheets highly popular in architectural and decorative applications, as they can be customized to meet specific design requirements. Additionally, anodized aluminum sheets possess excellent thermal and electrical conductivity. The process of anodization does not significantly impact these inherent properties of aluminum. Consequently, anodized aluminum sheets can efficiently dissipate heat and conduct electricity, making them well-suited for applications such as heat sinks, electronic enclosures, and electrical components. To sum up, anodized aluminum sheets possess enhanced corrosion resistance, improved scratch resistance, a wide range of color options, and excellent thermal and electrical conductivity. These properties render anodized aluminum sheets a versatile and durable material for various industries and applications.
Q:What are the different methods of polishing aluminum sheets?
There are several different methods available for polishing aluminum sheets, each with its own advantages and disadvantages. Some of the common methods include: 1. Mechanical polishing: This method involves using abrasive materials, such as sandpaper or abrasive pads, to manually rub the surface of the aluminum sheet. This process requires a lot of physical effort and can be time-consuming, especially for larger sheets. Mechanical polishing can achieve a high level of shine and smoothness, but it may leave behind scratches or marks if not done carefully. 2. Chemical polishing: Chemical polishing involves using chemical compounds to dissolve a thin layer of the aluminum surface, resulting in a smoother and shinier finish. This method is often used for larger sheets or complex shapes where mechanical polishing is not feasible. However, it requires careful handling of chemicals and may not be suitable for all types of aluminum alloys. 3. Electropolishing: This is an electrochemical process that uses an electric current to remove a thin layer of material from the aluminum surface. Electropolishing provides a smooth and shiny finish and can be used for both small and large sheets. It is particularly effective for removing surface imperfections and achieving a uniform appearance. However, it requires specialized equipment and expertise to ensure proper control of the process. 4. Vibratory finishing: In this method, the aluminum sheets are placed in a vibratory machine along with abrasive media, such as ceramic or plastic chips. The constant movement and friction between the sheets and the media help to remove surface imperfections and achieve a polished finish. Vibratory finishing is suitable for large batches of sheets and can be a cost-effective option. However, it may not provide the same level of shine as other methods. 5. Buffing and polishing compounds: These compounds are applied to the surface of the aluminum sheets and then buffed using a rotary tool or polishing machine. The compounds contain abrasive particles that help to remove scratches and bring out the shine in the metal. This method is relatively quick and easy to use, but it may not be as effective for heavy oxidation or deep scratches. Overall, the choice of polishing method depends on factors such as the size and type of the aluminum sheets, desired level of shine, and available equipment and expertise. It is recommended to test different methods on a small area before proceeding with the full polishing process to ensure satisfactory results.
