FAQ

I have been doing this science prac at school and I have received some strange results. I measured the density of this metal, which leads me to believe it is Aluminium. Also, its silvery appearance supports this. When I have attempted to react it with Hydrochloric Acid, Sulfuric Acid and the nitrates/chlorides of a few metals, I have received some odd results.Despite having a high reactivity, the only substance it has reacted with so far out of all of the above is Tin Chloride. Am I doing something wrong? Is it possible that it isn't aluminium and rather a similar metal such as zinc? Thanks in advance :)
Aluminum is very reactive so what happens is that it has a coat aluminum oxide as soon as it comes in contact with oxygen the outer layer forms aluminum oxide Al2O3. That is why Aluminum does not rust. The Al203 coat protects it.
Certainly, electrical bus bars can indeed utilize aluminum sheet. Aluminum is widely employed in electrical applications because of its exceptional conductivity and cost-effectiveness. Its electrical conductivity is high, comparable to copper, enabling it to effectively carry significant currents. Moreover, aluminum is lightweight and exhibits commendable resistance against corrosion, rendering it a favored option for bus bars in specific applications. Nevertheless, it is crucial to carefully evaluate the electrical system's specific requirements and standards before opting for aluminum sheet as bus bars.
Aluminum is put into copper chloride and how can you tell what happens to them visually?
Aluminum will reduce copper ions (and be oxidized) when chloride ions are present. Otherwise aluminum metal will pretty much just sit there. The reason is the passivating layer of Al2O3 on the surface of any piece of aluminum. This metal oxide layer prevents the metal from actually reacting. But in the presence of chloride ion in water, Al2O3 will react, resulting in AlCl4^- and OH- ions. Al2O3(s) + 8Cl- + 3H2O(l) -- 2AlCl4^- + 6OH- This allows the aluminum metal to come into contact with copper ions resulting in the redox reaction: 2Al(s) + 3Cu2+ -- 2Al^3+ + 3Cu(s) There is a side reaction where aluminum metal reacts with water, and hydrogen gas is produced. 2Al(s) + 2H2O --2 AlOH^2+ + H2(g) When you actually observe the reaction, you will see copper metal being formed, aluminum metal dissolve and bubbles of hydrogen gas being given off. ============ Follow up ============= Because of the passivating effect of Al2O3 and the fact that Al2O3 dissolves in the presence of Cl- forming a new complex ion, AlCl4^-, Brian's answer leaves out a lot of the important chemistry.
Yes, aluminum sheets can be suitable for chemical storage tanks depending on the specific requirements of the chemical being stored. Aluminum is known for its excellent corrosion resistance, which makes it suitable for storing many chemicals. It forms a protective oxide layer that prevents further corrosion, even when exposed to harsh environments. However, it is important to consider the compatibility of the chemical with aluminum. Some chemicals, such as strong acids or bases, may react with aluminum and cause corrosion or other undesirable reactions. In such cases, alternative materials like stainless steel or fiberglass-reinforced plastic (FRP) may be more suitable. Additionally, the thickness and grade of the aluminum sheets should be chosen carefully based on the specific chemical being stored and the tank's intended use. Thicker sheets may be necessary for storing highly corrosive or hazardous chemicals, while thinner sheets may be sufficient for less aggressive substances. Overall, aluminum sheets can be a suitable choice for chemical storage tanks, but it is crucial to carefully evaluate the chemical compatibility and select the appropriate thickness and grade of aluminum to ensure safe and reliable storage.
Yes, aluminum sheets can be used for automotive applications. Aluminum is lightweight, strong, and has excellent corrosion resistance, making it an ideal material for various automotive components such as body panels, hoods, doors, and engine parts.
I've created a sculpture out of aluminum foil, but it's pretty flimsy. What can I paint or cover it with that would harden and support it? I was thinking a resin or something, but I have no experience with resins or epoxies... Any suggestions?
Rigid Wrap is plaster-infused gauze. You can buy it at the art supply store or at a medical supply store. The latter is cheaper. It comes on a roll so you can cut off small chunks. Wet each piece and apply it to your sculpture. The first layer may be the most difficult. I would wrap the plaster gauze around the structure so the gauze overlaps gauze. It may not stick to the aluminum but it will stick to itself. Start at the bottom and let it dry, then add another layer. As mentioned, adding too much may compromise the structure so work slowly and allow time to dry between layers.
Is this aluminium plate ceiling dark keel or bright keel?
Although as upstairs said, now integrated ceiling are dark fitted keel. Can see your picture, elevation difference also has, should be bright install keel. This requires manufacturers and roof distribution. It is not important to open and install, but the key is where to enter such plates.If you think about the effect, consider getting the information from the scene.
I have a project on the aluminum element. What are the advantages and disadvantages of this element?...What are the risks/dangers?...Thank you so much ---And please tell me where I could find this information too.
Disadvantages: * Far more expensive that steel. * Limited to certain geometric features using economical processes. * Abrasive to tooling (aluminum oxide is very abrasive). * Difficult to weld. * Prone to severe spring back. Advantages: Aluminum is the preferred choice for fencing due to several inherent advantages of aluminum. The main advantage is that aluminum components do not rust as easily as iron. Aluminum fences are given a powder-coat finish that protects the surfaces. This kind of a finish also enhances its appearance and provides a smooth surface for painting, if desired. All the components of the fence are drilled and powder-coated prior to assembly. Extreme care is taken during assembly by using sturdy fasteners, brackets, and rivets. Wherever these fasteners, etc., need to be visible, attractive stainless steel ones are used. This provides both looks and strength. As aluminum is an easy metal to work with, a plethora of style choices and adornment options are made available to clients. The flexibility of the metal allows for several designs that can complement the facade of the structure they are installed around.
