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: what language did Aluminum and Uranium originate from ? Who or what were they named for ?
- The ancient Greeks and Romans used alumen (alum, potassium aluminium sulfate, K2Al6(OH)12(SO4)4) in medicine as an astringent, and as a mordant in dyeing. Alum was exported from ancient Greece and Italy. In 1761 the French chemist Louis-Bernard Guyton de Morveau (1737-1816) proposed the name alumine for the base in alum. Guyton de Morveau was instrumental in setting up a standardised system for chemical nomenclature and often collaborated with Antoine Lavoisier, who in 1787, suggested that alumine was the oxide of a previously undiscovered metal. In 1808, Sir Humphry Davy (1778-1829) did experiments for the decomposition of alumine, silex, zircone, and glucine. He failed to isolate the metals in these, as he reported in his paper for the Royal Society of London on 30 June 1808, but he suggested names for the metals (note) Cf. Silicium, Zirconium, and Beryllium (Glucium) Thus he proposed the name alumium for this still undiscovered metal and later agreed to change it to aluminum. Shortly thereafter the name aluminium was adopted to conform with the -ium ending of most elements. Uranium was named by its discoverer German chemist Martin Klaproth, after the last planet to have been discovered Uranus.
- Q: What are the different grades of aluminum used in coil production?
- Coil production utilizes various grades of aluminum, each possessing its own unique properties and characteristics suitable for specific purposes. Some commonly employed grades include: 1. Commercially pure aluminum, known as 1100 Aluminum, excels in corrosion resistance and boasts high thermal conductivity. It finds applications in heat exchangers, fin stock, and evaporator coils. 2. 3003 Aluminum, alloyed with manganese, offers increased strength and durability compared to 1100 aluminum. Its formability and weldability properties make it suitable for a wide range of coil production applications, such as roofing, gutters, and general sheet metal work. 3. Magnesium alloyed 5052 Aluminum exhibits exceptional corrosion resistance and high strength. It is frequently utilized in marine applications like boat hulls and components, as well as architectural and automotive applications. 4. Renowned for its high strength and excellent machinability, 6061 Aluminum is considered one of the most versatile aluminum alloys. It commonly finds use in structural applications like aircraft parts, truck frames, and industrial equipment. 5. The aerospace and defense industries commonly rely on 7075 Aluminum, which offers one of the highest strength aluminum alloys. It demonstrates excellent fatigue resistance and is often employed in the production of aircraft wing spars, fuselage frames, and missile components. These examples highlight the diverse grades of aluminum employed in coil production. The selection of a specific grade depends on the desired properties and requirements of the intended application.
- Q: What is the typical coefficient of friction for aluminum coils?

- Q: What is the typical lead time for ordering aluminum coils?
- The lead time for ordering aluminum coils can vary depending on factors such as the supplier, quantity ordered, and current market conditions. Typically, lead times for aluminum coils can range from a few weeks to several months. If the supplier has the coils readily available in their stock, the lead time can be relatively short, usually around 2-4 weeks. This is the case when the supplier consistently maintains inventory and has the desired specifications and quantities ready for immediate shipment. However, if the coils need to be customized or if the supplier lacks sufficient stock, the lead time can be longer. Customizing aluminum coils may require additional processing time, such as rolling, annealing, or coating, which can extend the lead time by a few weeks or even months. Moreover, lead times can be influenced by market conditions and demand fluctuations. When there is high demand or disruptions in the supply chain, lead times may increase due to limited availability of raw materials or production capacity. For a more accurate estimate of the lead time for ordering aluminum coils, it is advisable to directly contact the specific supplier or manufacturer. They can provide detailed information based on their current inventory, production capabilities, and any other factors that may impact lead times.
- Q: What are the weight savings achieved by using aluminum coils?
- The weight savings achieved by using aluminum coils can vary depending on the specific application, but generally speaking, aluminum coils are significantly lighter than traditional materials such as steel. On average, aluminum coils can provide weight savings of around 50% or more compared to steel coils. This weight reduction is especially beneficial in industries like automotive, aerospace, and construction, where lighter materials can contribute to improved fuel efficiency, increased load capacity, and enhanced overall performance.
- Q: Is it appropriate to use a hammer to open or unroll an aluminum coil?
