FAQ

Marine applications can indeed utilize aluminum coils. The popularity of aluminum in this field can be attributed to its remarkable resistance to corrosion, lightweight nature, and impressive strength-to-weight ratio. Boats, ships, and other marine structures are commonly constructed using aluminum due to these advantages. Specifically, aluminum coils are especially valuable in marine applications because they can be easily shaped and sized to fit different marine industry parts and components. Moreover, these coils possess the ability to endure harsh marine environments and exhibit exceptional resistance to corrosion caused by saltwater, a major concern in marine applications. All in all, the utilization of aluminum coils in marine applications is a dependable and efficient choice.

First write out the formula reaction: 4Al + 3O2 --- 2Al2O3 Next, find the number of moles of oxygen gas needed to oxidize 3.42 g of aluminium completely. From the cchemical equation above, 3 mol of oxygen is used to oxidize completely 4 mol of aluminium. Calculate the no. of moles of aluminium used: no. of moles of aluminium used = 3.42 g / molar mass of Al = 3.42 g / 26.98 g mol^-1 = 0.127 mol Use the mole ratio concept to find the no. of moles of oxygen required: no. of moles of oxygen required : no. of moles of aluminium used = 3 : 4 no. of moles of oxygen required / 0.127 = 3 / 4 no. of moles of oxygen required = (3 / 4)(0.127) = 0.095 mol Next, use the gas equation PV = nRT [P: Pressure of gas in Pa; V: Volume of gas in m^3; n: no. of moles; R, gas constant, 8.314 J mol^-1 K^-1; T, Temperature of gas in K] -Convert 0.975 atm to Pa: 0.975 atm = (0.975 x 101325) Pa = 98791.875 Pa -Convert 25 oC to K: 25 oC = (25 + 273) K = 298 K -Substitute into the equation PV = nRT and solve it: (98791.875)(V) = (0.095)(8.31)(298) (98791.875)(V) = 235.2561 V = 235.2561 / 98791.875 = 0.002381 m^3 = (0.002381 x 10^3) L = 2.381 L

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.

If this is true then how do I take my aluminums temperature without fear of breaking the themometer and get mercury all over it?

It's easy - don't use a mercury thermometer. In fact, don't use a liquid thermometer at all. Go solid state and use a contact thermocouple thermometer - cheap as sh*t and accurate to 0.1C. Or, if the temp is high and relatively inaccessible, use an infrared or laser pyrometer.

Food packaging can indeed utilize aluminum coils. Aluminum is extensively employed in the food packaging sector because of its various advantageous characteristics. To start off, aluminum serves as a non-toxic and non-reactive substance, ensuring that harmful substances do not leach into the food. Moreover, it acts as an impermeable barrier to gases and moisture, effectively safeguarding the food from oxygen, light, and moisture that could spoil its quality or alter its taste. In addition, aluminum coils are lightweight, facilitating their transportation and handling. They are also highly malleable, enabling them to be easily shaped and formed into various packaging designs. Additionally, aluminum's heat conductivity properties are commendable, allowing for efficient heat transfer during food processing or cooking. Finally, aluminum demonstrates its commitment to the environment as a sustainable and recyclable material, making it an eco-friendly choice for food packaging. Overall, due to its safety, barrier properties, lightweight nature, flexibility, heat conduction capabilities, and sustainability, aluminum coils are a suitable and widely embraced option for food packaging.

Yes, aluminum coils can be used in the production of electronic components. Aluminum is a versatile and widely used metal in various industries, including electronics. It offers several advantages such as lightweight, high thermal conductivity, corrosion resistance, and excellent electrical conductivity. These properties make aluminum coils suitable for applications in electronic components like capacitors, transformers, inductors, and heat sinks. The use of aluminum coils in electronic components enables efficient heat dissipation, improved performance, and reduced overall weight of the electronic devices.

Aluminum coils are generally not suitable for high-strength applications due to their relatively low tensile strength compared to other materials such as steel. Aluminum has a lower strength-to-weight ratio and is more prone to deformation under high loads. However, there are specific alloys of aluminum that have been developed to enhance their strength, such as the 7000 series aluminum alloys, which can offer higher strength levels. These alloys are commonly used in aerospace and automotive industries for their lightweight properties and moderate strength. Nevertheless, for applications requiring the utmost strength, steel or other high-strength materials are usually preferred over aluminum coils.

The different packaging weights available for aluminum coils vary depending on the specific requirements and applications. Common packaging weights for aluminum coils range from 1,000 to 10,000 pounds or more. These weights can be customized to meet the needs of different industries and transportation methods.
