Aluminium is a relatively soft,durable, lightweight, ductile and malleablemetalwith 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 light and an excellent reflector (asmuch as 98%) of medium and far infrared radiation. The yield strengthof pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the density and 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.

- Q: Why are the aluminum coils sticky after annealing?
- There is oil or the annealing time is too long!
- Q: How are aluminum coils tested for strength and durability?
- Aluminum coils are tested for strength and durability through a rigorous process that involves several methods. One common method is tensile testing, which measures the maximum amount of stress a coil can withstand before it breaks or deforms. This test helps determine the overall strength and elasticity of the aluminum. Another important test is the hardness test, which measures the resistance of the aluminum coil to indentation or scratching. This test helps determine the durability and wear resistance of the material. Furthermore, aluminum coils are often subjected to fatigue testing, where the material is repeatedly subjected to cyclic loading and unloading. This test helps simulate real-life conditions and assesses the coil's ability to withstand repeated stress without failure. Additionally, corrosion resistance is a critical factor in determining the durability of aluminum coils. Therefore, various corrosion tests are conducted, such as salt spray testing, to assess the coil's resistance to environmental factors that may lead to corrosion or degradation over time. In some cases, non-destructive testing methods like ultrasonic testing or eddy current testing are employed to detect any internal defects or inconsistencies within the coil that may affect its strength and durability.

Always check the manufacturer's guidelines for safe use.</p>
- Q: How do aluminum coils compare to galvanized steel coils in terms of longevity?
- Compared to galvanized steel coils, aluminum coils typically have a longer lifespan when it comes to longevity. Aluminum is naturally resistant to corrosion, meaning it is less prone to rust or deterioration over time. As a result, aluminum coils are widely chosen for outdoor purposes, including roofing, siding, and HVAC systems, as they can endure harsh weather conditions while maintaining their structural integrity. In contrast, galvanized steel coils are coils made of steel that are coated with a layer of zinc as a protective measure against corrosion. Although this zinc coating offers some degree of protection, it can eventually wear away, especially in areas with high humidity or exposure to saltwater. Once the zinc coating is compromised, the underlying steel becomes vulnerable to rust and corrosion, significantly diminishing the lifespan of galvanized steel coils. Consequently, if longevity is a primary concern, aluminum coils are typically a more resilient and enduring option compared to galvanized steel coils. Nevertheless, it is crucial to take into account other factors such as cost, specific application requirements, and maintenance needs before reaching a final decision.
