Aluminium is a relatively soft, durable, lightweight, ductileand 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 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:I'm asking about the aluminum tabs on soda cans. I've heard mixed things.
Depends what you mean by site. A full service junkyard will pay by the pound for most kinds of metal, including washers dryers and stoves but you would need a lot of them to make it worthwhile at 60 cents a pound or so
Q:How do aluminum coils compare to stainless steel coils in terms of durability?
Aluminum coils are generally less durable than stainless steel coils. While aluminum coils are lightweight and corrosion-resistant, they are prone to denting and are not as strong as stainless steel. On the other hand, stainless steel coils are highly durable, resistant to dents, and have a longer lifespan.
Q:i have a project that requires me to know how safeway aluminum foil is made. i researched it on the internet, and also called safeway for it. they never gave me an answer. same for the diamond aluminum foil.please help!!!!i just need to know where they make it, how thick it is, and/or information about the ingots (such as size)and also temp. of heating room
they start with a huge block of aluminum, then run that forth and back between giant steel cylinders until it is a relatively thin and very long sheet of metal. Then this sheet is run trough a series of these drums until it is foil of the required thickness. Then they cut the wide foil in strips of the right width and package it for sale. Hope this helps.
Q:How are aluminum coils measured and specified?
Aluminum coils are measured and specified based on several key factors. The first aspect is the thickness of the coil, which is typically measured in gauge or millimeters. The thickness determines the strength and durability of the coil, with thicker coils being more robust. Another important specification is the width of the coil, which is usually measured in inches or millimeters. The width determines the size and coverage area of the coil, with wider coils offering greater coverage. The length of the coil is also a crucial specification. It is typically measured in feet or meters and determines the amount of material available for a specific project. Longer coils are often preferred as they minimize the number of joints required during installation. Additionally, the alloy and temper of the aluminum used in the coil are specified. Different alloys have varying mechanical and chemical properties, making them suitable for different applications. The temper refers to the heat treatment process applied to the aluminum, affecting its hardness and flexibility. Coil weight is another important consideration. It is typically measured in pounds or kilograms and determines the handling and transportation requirements for the coil. Lastly, the surface finish of the coil is specified. Common finishes include mill finish, which is untreated, and coated finishes such as painted or anodized. The surface finish affects the appearance and corrosion resistance of the coil. Overall, the measurement and specification of aluminum coils involve factors like thickness, width, length, alloy, temper, weight, and surface finish. These specifications help ensure that the coils meet the desired requirements for various applications.
Q:Are there any special considerations for handling and storing aluminum coil scraps?
Yes, there are special considerations for handling and storing aluminum coil scraps. It is important to segregate aluminum scraps from other metals to prevent contamination. They should be stored in a dry and well-ventilated area to avoid moisture absorption and potential corrosion. Additionally, proper labeling and organization are crucial to ensure easy identification and retrieval of the scraps when needed.
Q:How are aluminum coils tested for surface cleanliness?
Aluminum coils are typically tested for surface cleanliness using various methods such as visual inspection, solvent wipe tests, and surface roughness measurements. Visual inspection involves examining the surface of the coil for any visible contaminants or defects. Solvent wipe tests involve wiping the surface with a solvent-soaked cloth to check for any residue or contaminants that may be present. Surface roughness measurements are taken using specialized instruments to assess the smoothness of the coil's surface, which can indirectly indicate its cleanliness. These testing methods help ensure that aluminum coils meet the required standards and are free from any surface contaminants.
Q:What is the minimum order quantity for aluminum coils?
The minimum order quantity for aluminum coils can vary depending on the supplier and specific product requirements. Some suppliers may have a minimum order quantity of one coil, while others may require a minimum order quantity of several coils or even a full container load. It is best to contact the specific supplier or manufacturer to inquire about their minimum order quantity for aluminum coils as it can vary.
Q:Are there any limitations to the minimum coil length of aluminum coils?
Yes, there are limitations to the minimum coil length of aluminum coils. The minimum coil length is determined by various factors such as the manufacturing process, equipment capabilities, and the intended use of the coils. One limitation is the size and capacity of the manufacturing equipment. Most coil production lines have a minimum length requirement to ensure efficient operation and to prevent damage to the coils during the manufacturing process. If the coil is too short, it may not be properly processed or handled by the equipment, leading to production issues or product defects. Another limitation is the intended use of the coils. Certain applications may require a minimum coil length to meet specific requirements or to ensure optimal performance. For example, in industries such as construction or automotive, coils are often used to make components or structures that have specific length requirements. In such cases, the minimum coil length is determined by the specifications of the end product. Additionally, handling and transportation considerations also play a role in determining the minimum coil length. Coils that are too short may be more difficult to handle, transport, or store, making them less practical or cost-effective. In summary, the minimum coil length of aluminum coils is subject to limitations imposed by manufacturing equipment capabilities, intended use, and practicality in terms of handling and transportation. These limitations ensure efficient production processes, adherence to product specifications, and practicality in the overall supply chain.
