1)what is aluminum?
Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface.
Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.

- Q: What is the typical price gap between purchasing new aluminum coils versus used ones?
- <p>The price difference between new and used aluminum coils can vary significantly based on factors such as the quality of the used coils, market demand, and the specific grade of aluminum. On average, used aluminum coils can be 20-50% cheaper than new ones. However, this is a broad estimate and actual prices can fluctuate. It's essential to check current market prices and consider the condition of the used coils before making a purchase decision.</p>
- Q: Are there any restrictions on the coil flatness of aluminum coils?
- Yes, there are restrictions on the coil flatness of aluminum coils. The industry standards specify acceptable tolerances for coil flatness to ensure the quality and usability of the aluminum coils. These restrictions help prevent any deformation or irregularities in the coils, ensuring they meet the required specifications for various applications.
- Q: I take an extracurricular aircraft class, and I got the okay to take some old painted sheet aluminum for another project I'm working on. The problem is, what I'm using it for I need bare aluminum. I heard around that air crafts are painted with something that regular (store-bought) paint stripper can't remove. Is this true? I am aware of the fact that stripping something like that will result in a toxic paint sludge, so I've taken precautions for that. I just need to know if heavy-duty paint stripper from Home Depot will do the job. Thanks :)
- Go to an automotive paint store like Sherwin Williams Auto Paints, buy a stripper for the type of paint on the aluminum. Many are epoxy or special acrylics like acry glo or jet glo paints and home paint strippers usually won't phase those paints. A methylene chloride mixed with a soap or wax carrier will work but is a hazmat item and has to be disposed of properly but it won't be corrosive to the aluminum. Dupont, Sherwin Williams, and others make the proper strippers. You might even find some at an RV or Boat supply.
- Q: Can aluminum coils be used for marine applications?
- Yes, aluminum coils can be used for marine applications. Aluminum is a popular material choice for marine applications due to its excellent corrosion resistance in saltwater environments. It has a natural oxide layer that forms on its surface, providing protection against corrosion. Aluminum coils are commonly used for marine applications such as boat hulls, decks, and structures. Additionally, aluminum is lightweight, which contributes to fuel efficiency and improved performance in marine vessels. Its high strength-to-weight ratio makes it an ideal choice for constructing boats and other marine equipment. However, it is important to select the appropriate grade of aluminum alloy that is specifically designed for marine applications to ensure optimal performance and longevity.
