2.Description
In Europe aluminium experiences high rates of recycling, ranging from 42% of beverage cans, 85% of
construction materials and 95% of transport vehicles.Recycled aluminium is known as secondary aluminium, but maintains the same physical properties as primary aluminium. Secondary aluminium is produced in a wide range of formats and is employed in 80% of alloy injections. Another important use is for extrusion.
White dross from primary aluminium production and from secondary recycling operations still contains useful quantities of aluminium that can be extracted industrially.The process produces aluminium billets, together with a highly complex waste material. This waste is difficult to manage. It reacts with water, releasing a mixture of gases (including, among others, hydrogen, acetylene, and ammonia), which spontaneously ignites on contact with air;contact with damp air results in the release of copious quantities of ammonia
gas. Despite these difficulties, the waste has found use as a filler in asphalt and concrete.

5.FAQ：
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.
2)What's kind of payment term we can supply?
CIF,CFR, FOB and other.
3)Can we supply samples?
Yes, we can!
- Q: Where can I purchase used aluminum coil over the internet?
- <p>Yes, you can buy used aluminum coil online. There are various online platforms and marketplaces where you can find used aluminum coils for sale. Websites like eBay, Alibaba, and specialized metal trading platforms often list used aluminum coils. Additionally, you can check with local recycling centers or metal suppliers who may have used aluminum coils available. Always ensure to verify the condition, specifications, and authenticity of the product before making a purchase.</p>
- 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: Can aluminum coils be used for decorative purposes?
- Yes, aluminum coils can be used for decorative purposes. They are commonly used in various decorative applications such as trim work, wall panels, ceilings, and decorative accents. Aluminum coils offer versatility in terms of color, texture, and finish, allowing for creative and aesthetically pleasing designs.
- Q: What are the recognized standards that dictate the quality of aluminum coil?
- <p>Yes, there are several standards that define the quality of aluminum coil. These include ASTM B209, which specifies requirements for aluminum and aluminum alloy flat sheet, coil, and plate for general usage. ASTM B210 covers aluminum and aluminum alloy sheet and plate for heat-treating. Additionally, EN 485 is a European standard that specifies the requirements for aluminum and aluminum alloy cold-rolled sheets, strips, and plates. These standards outline dimensions, chemical composition, mechanical properties, and other quality aspects to ensure the material meets industry requirements.</p>
- Q: Why do we need aluminum when cooking in the oven at all.
- Keeps the top from getting over cooked and the foil keeps the steam in so your food with be moist.
- Q: so i have a dirtbike and i wanted to polish the swing arm.i have 100 grit,400,800 and 1200.i use to 100 to take off the coating the swing arm has and once its off its like a natural aluminum left.well i polished it before and it came out real good to a mirror finish.well i did the other half of the swing arm exactly the same even with new sand paper and it just didnt shine like the other half!i wet sanded it and i used car wax as my buffing compound,yes i used a soft buffing wheel.the car wax works really good!thats how i got the first half to a mirror shine but the other half just wasnt working for me.any suggestions?oh and i sanded in all one direction.
- Use 1200 to 2000 grit. Your sandpaper is way too course! The paper probably got gummed up With aluminum particals. Use water or oil to wash away particals. In other words wet sand it. Then get this polish called Mothers Aluminum Polish. And two micro fiber cloths. Use the mothers and wipe off with first towel. Then use second towel. Trust me! I spend alot of time in my machine shop making custom aluminum parts. If you can trickle water over the surface of what your polishing it helps. The 1200 to 2000 grit can be purchased at Walmart in the auto section.
- Q: This question asks for a comparison between single-coil and multi-coil aluminum tubes, highlighting their differences.
- <p>Single-coil aluminum tubes are made with a single layer of aluminum wound into a cylindrical shape, offering simplicity and ease of manufacturing. They are typically used in applications requiring basic heat exchange or formwork. In contrast, multi-coil aluminum tubes consist of multiple layers of aluminum wound together, which can provide greater strength and durability. They are often utilized in more demanding applications where higher pressure resistance and thermal efficiency are required, such as in high-performance heat exchangers or industrial processes. The multi-coil design also allows for better heat distribution and can handle more stress without deformation.</p>
- Q: How are aluminum coils packaged for transportation?
- Aluminum coils are typically packaged for transportation by first being tightly wound and then securely strapped with steel bands. They are often placed on pallets and covered with protective materials such as plastic or cardboard to prevent damage during transit. Additionally, the coils may be loaded into containers or onto flatbed trucks, ensuring proper handling and stability throughout the transportation process.
- Q: Which is more unhealthy the bleached parchment paper or the aluminum from the pan?
- Parchment paper is siliconized and the aluminum is stabalized. Based on that choice you're not any more or less safer with either or both.
- Q: Can aluminum coils be custom-made to specific requirements?
- Yes, aluminum coils can be custom-made to specific requirements. Aluminum coils are versatile and can be tailored to meet a wide range of specifications and applications. Manufacturers can customize the dimensions, thickness, width, and length of the coil to accommodate specific requirements. Additionally, various surface finishes, such as embossed patterns or coatings, can be applied to enhance the appearance or improve functionality. Customization of aluminum coils allows for precise matching of specific needs in industries such as construction, transportation, aerospace, and many others.
