Aluminium is a relatively soft, durable, lightweight, ductileand malleable metalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

Q:An aluminum bar 3.80 m long has a rectangular cross section 1.00 cm by 5.00 cm, what is the resistance and what is the length of a copper wire 1.50 mm in diameter having the same resistance?: Resistance equals resistivity times length divided by cross-sectional area. R = ρ?l/A The resistivities at 20°C are aluminum ρ = 2.82×10??Ωm copper ρ = 1.72×10??Ωm So the aluminum bar with rectangular cross section has a resistance of R = ρ?l/(a?b) = 2.82×10??Ωm ? 3.8m / (0.01m ? 0.05m) = 2.1432×10??Ω The resistance of copper wire with circular cross section is given by R = ρ?l/(π?d?/4) = 4?ρ?l/(π?d?) Hence a wire of same resistance as the aluminum bar has a length of l = R?π?d? / (4?ρ) = 2.1432×10??Ω ? π ? (0.0015m)? / (4?1.72×10??Ωm) = 0.0220m = 2.2cm

Q:How are aluminum coils coated or treated for specific applications?: To cater to specific applications, various methods are employed to coat or treat aluminum coils. One commonly used approach involves the application of a protective coating, such as a polymer or paint, to enhance durability and resist corrosion. This coating is typically applied through a process known as coil coating, which evenly spreads a thin layer of coating material onto the surface of the aluminum coil. The coil coating process consists of several steps. Firstly, the aluminum coil undergoes a cleaning procedure to eliminate any impurities or contaminants. This step is crucial in ensuring that the coating adheres properly to the metal surface. Following the cleaning process, a chemical pre-treatment is applied to the coil to enhance bonding between the aluminum and the coating material. Once the pre-treatment is complete, the coil is fed through a coating machine where the coating material is applied. The choice of coating material, whether it be liquid paint, powder coating, or a thin film, depends on the specific requirements of the application, such as desired appearance, durability, or chemical resistance. After the coating is applied, the coil is subjected to a curing process, which may involve baking the coil at high temperatures or exposing it to ultraviolet light. This curing process ensures that the coating material adheres effectively to the aluminum surface, providing excellent protection and longevity. In addition to protective coatings, aluminum coils can also undergo other treatments for specific applications. An example of this is anodizing, a process that creates a thick, durable oxide layer on the surface of the aluminum. Anodizing enhances corrosion resistance, improves aesthetics, and can also serve as a base for further coatings or treatments. Furthermore, aluminum coils can be laminated with other materials for specific applications. For instance, they can be laminated with plastic films or adhesive coatings to provide insulation, moisture resistance, or other special properties. In conclusion, aluminum coils are coated or treated in various ways to meet the requirements of specific applications.
