Q: I have my brother's old wooden crutches but i see everyone using aluminum and i have the option to get aluminum ones. Is there any reason why they'd be better then my wooden ones?: Aluminum are lighter..........And I guess after a day of using Wooden Crutches...you can get really tired because of the exra weight your lugging around.

Q: What is the typical coefficient of thermal expansion for aluminum coils?: Aluminum coils usually have a coefficient of thermal expansion around 23 x 10^-6 per degree Celsius. This implies that with each degree Celsius rise in temperature, the length of the aluminum coil will expand by 23 parts per million. The coefficient of thermal expansion holds significance in the design and handling of aluminum coils, as it impacts their dimensional stability and can induce thermal strains in the material due to temperature fluctuations.

Q: What is the elongation of aluminum coils?: The elongation capacity of aluminum coils pertains to the extent to which the coils can be stretched or lengthened before they surpass their breaking threshold. It serves as an indicator of the material's ductility or its capacity to undergo plastic deformation without experiencing fracture. Generally, aluminum coils demonstrate a notably high elongation percentage, usually ranging between 10% and 30%, signifying their considerable stretchability prior to breakage. This particular attribute renders aluminum coils fitting for diverse applications necessitating flexibility and resilience, including the production of electrical cables, automotive components, and construction materials.

Q: This question asks whether aluminum coils can be utilized in various forms and dimensions.: <p>Yes, aluminum coils can be used in different shapes and sizes. They are versatile and can be cut, shaped, or rolled into various forms to suit specific applications. Aluminum's malleability allows it to be easily manipulated, making it suitable for a wide range of industries, including construction, automotive, and packaging. The size of aluminum coils can also vary, from small coils used for crafts to large ones used in industrial applications. The versatility of aluminum coils makes them a popular choice for many different projects and industries.</p>

Q: How many companies have used aluminum coil?: Too many. All the companies who make the aluminum products you have seen in daily life have used it. So it is hard to explain.

Q: How do aluminum coils contribute to the corrosion resistance of marine applications?: Aluminum coils play a crucial role in enhancing the corrosion resistance of marine applications. This is primarily due to the unique properties and characteristics of aluminum as a material. Firstly, aluminum has a natural oxide layer that forms on its surface when exposed to air, which is highly resistant to corrosion. This oxide layer acts as a protective barrier that prevents further oxidation and corrosion of the metal. This inherent property of aluminum makes it an ideal choice for marine applications, where constant exposure to saltwater and moisture can be highly corrosive. Furthermore, aluminum coils can be alloyed with other elements such as magnesium and manganese to further enhance their corrosion resistance. These alloying elements not only strengthen the aluminum but also improve its resistance to pitting and crevice corrosion. Pitting corrosion occurs when localized damage to the oxide layer exposes the underlying metal, while crevice corrosion occurs in areas where oxygen is restricted, such as gaps or joints. By alloying aluminum, the coils become more resistant to these types of corrosion, making them highly suitable for marine environments. Moreover, aluminum coils can be coated with protective finishes such as anodizing or painting, which provide an additional layer of protection against corrosion. Anodizing involves creating a thicker and more durable oxide layer on the aluminum surface, thereby increasing its resistance to corrosion. Painting, on the other hand, acts as a physical barrier that shields the coils from direct contact with corrosive elements present in the marine environment. In conclusion, aluminum coils contribute to the corrosion resistance of marine applications through their natural oxide layer, alloying with other elements, and the option of protective finishes. These characteristics make aluminum coils highly durable and capable of withstanding the harsh conditions encountered in marine environments, ensuring their longevity and reliability.

Q: I know that Aluminum is a metal, and it's corrosive, but I've been wondering about how Aluminum Foil is created. Is it the same as the metal? Just pounded down? or is it a mixture of different elements?: It is made by rolling an aluminum block thinner and thinner. Metal foil, such as tin foil had been around for years. The first plant designed for rolling aluminum foil was opened in 1910. NASA was not in existence then. It appears the inventor was: Hans Christian Oersted Year Invented: 1825 P.S. Aluminum is not corrosive. corrosive means it corrodes other things (as acid would). It does corrode. It is also the most reactive metal. It is oxidized immediately upon exposure to air - why it is difficult to solder. The aluminum oxide is not whetted by solder. Aluminum oxide is a ceramic, called Alumina. Anodized aluminum has has a thick layer of aluminum oxide formed on its surface

Q: Can aluminum coils be used in food processing or packaging?: Yes, aluminum coils can be used in food processing or packaging. Aluminum is a preferred material for food-related applications due to its non-toxicity, corrosion resistance, and ability to maintain product freshness and quality. It is commonly used in food packaging, such as cans, foil, and trays, and is also utilized in food processing equipment like cookware and machinery.

Q: For the reaction at the anode:Al ----gt; Al3+ + 3eHowever, at the anode, oxygen are also produced and forms aluminium oxide(Al2O3) with aluminium.Are Oxygen produced by oxidation of water by electrolysis? or some reaction else?If Oxygen are produced by oxidation of water, then why it can be oxidise sinceAl ----gt; Al3+ + 3e E^0= + 1.66V2H2O ---gt; O2 + 4H+ + 4e E^0= - 1.23V(if refers to E null value) Oxygen should only be produced after all the Al have been finish oxidised.Both reaction happen at the same time? Is it possible?: When Al is formed on the anode, it is immediately oxidized to Al2O3 because Al is very active. The oxygen come from the water. Actually, when you expose Al to the air, a layer of Al2O3 is formed and passivates the surface, this means, the surface do not continue oxidizing.

Q: Can aluminum coils be customized?: Yes, aluminum coils can be customized. They can be manufactured in various sizes, thicknesses, and shapes to meet specific requirements and applications. Additionally, they can undergo surface treatments, such as coatings or finishes, to enhance corrosion resistance or aesthetic appearance.
