FAQ

When using aluminum coils, weight considerations primarily involve the overall weight of the coils themselves and the impact it may have on transportation, installation, and structural support systems. Aluminum coils are preferred in various industries due to their lightweight nature, which enables easier handling and reduces the load on infrastructure. However, it is important to ensure that the weight of the coils aligns with the intended application and the capacity of the supporting structures. Additionally, factors such as coil thickness, width, and length should also be taken into account to determine the appropriate weight considerations when using aluminum coils.

ok-so lately I've noticed that everytime i wrap food in aluminum foil it starts to eat tiny holes in it! so far it has happened when I put it on chicken breasts and froze them--over a warm eggplant parm that i put in the fridge and now, today on coleslaw--which was never hot! what the heck is going on? I've never seen this before! any ideas? it is a name brand foil too...tx!

I have noticed that myself and thought it was just the new method of making the foil? or something I was putting on the foods I wrapped? well, I started using the cling wrap then the foil to seal it in and haven't had so much problem with the foil having those tiny holes in it that make the wrap not so air tight and the food doesn't get freezer burned any more either.

I would like to know why the ionic substance aluminium oxide doesn't dissolve in water.

Aluminium gives away 3 electrons, and two aluminium atoms are combined with 3 oxygen atoms, the charge is just to great for it to gracefully dissolve.

Aluminum coils come with limitations and restrictions that need to be taken into account. Some of the key limitations are as follows: 1. Corrosion: Aluminum is prone to corrosion, especially when exposed to certain chemicals or environments. This means it may not be suitable for applications where it will encounter corrosive substances or highly corrosive environments. 2. Strength: Although aluminum is lightweight, it lacks the strength of metals like steel. This limits its use in applications requiring high strength or load-bearing capabilities. 3. Temperature sensitivity: Aluminum has a lower melting point compared to other metals, which can be a drawback in applications involving high temperatures. It may not be suitable for certain industrial or high-temperature environments. 4. Electrical conductivity: While aluminum has good electrical conductivity, it falls short of copper's conductivity. This can limit its use in applications requiring high electrical conductivity, such as electrical wiring or power transmission. 5. Cost: Aluminum can be more expensive than other metals, making it less favorable in cost-sensitive applications. In such cases, alternative materials may be preferred. 6. Formability: Compared to some other metals, shaping or forming aluminum coils can be challenging. This restricts their use in applications that demand complex shapes or tight tolerances. When selecting aluminum coils for a specific purpose, it is crucial to consider these limitations and restrictions. A careful evaluation of the particular requirements and constraints will help determine whether aluminum coils are suitable or if alternative materials should be considered.

Aluminum coils are coated for corrosion resistance through a process known as coil coating. This involves applying a protective coating onto the surface of the aluminum coils to prevent oxidation and corrosion. The coating is typically a combination of primer and topcoat that is applied using various methods such as coil coating lines or spray applications. The coating acts as a barrier, protecting the aluminum from environmental factors such as moisture, chemicals, and UV radiation, thereby enhancing its durability and extending its lifespan.

ok me and my father are trying to make thermite. we have the iron oxide but the aluminum we only have paste and i was wondering would it work the same as if we had the powder.and if it is differnt will it work for the thermite and what will it take to light it.

How To Make Thermite

The gauge of aluminum coils directly influences their performance. Thicker gauge coils are more durable and resistant to physical damage, making them suitable for heavy-duty applications that require high strength and durability. On the other hand, thinner gauge coils are lighter and more flexible, making them more suitable for applications that require flexibility and ease of bending. Additionally, the gauge also affects the thermal conductivity and electrical resistance of the coils, with thinner gauges offering higher conductivity. Therefore, the gauge of aluminum coils plays a crucial role in determining their performance characteristics and suitability for specific applications.

Aluminum is directly below Mg. If aluminum is oxidized so readily, then how can we make planes or ships out of it and they don't fall apart after a few months or years?

Yes aluminum does oxidize just like any other metal. The difference is that aluminum oxidizes the same color as the metal therefore you cannot tell that is oxidizing. Once is oxidizes a little bit, the oxidize protects the metal and it does not oxidize any more.
