1.Description

Aluminium atoms are arranged in a face-centered cubic (fcc) structure. Aluminium has a stacking-fault energy of approximately 200 mJ/m2.


Aluminium is a good thermal and electrical conductor, having 59% the conductivity of copper, both thermal and electrical, while having only 30% of copper's density. Aluminium is capable of being a superconductor, with a superconducting critical temperature of 1.2 Kelvin and a critical magnetic field of about 100 gauss (10 milliteslas).


2.Chemical

Corrosion resistance can be excellent due to a thin surface layer of aluminium oxide that forms when the metal is exposed to air, effectively preventing further oxidation.The strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper.This corrosion resistance is also often greatly reduced by aqueous salts, particularly in the presence of dissimilar metals.


In highly acidic solutions aluminium reacts with water to form hydrogen, and in highly alkaline ones to form aluminates— protective passivation under these conditions is negligible. Also, chlorides such as common sodium chloride are well-known sources of corrosion of aluminium and are among the chief reasons that household plumbing is never made from this metal.


However, owing to its resistance to corrosion generally, aluminium is one of the few metals that retain silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium mirror finish has the highest reflectance of any metal in the 200–400 nm (UV) and the 3,000–10,000 nm (far IR) regions; in the 400–700 nm visible range it is slightly outperformed by tin and silver and in the 700–3000 (near IR) by silver, gold, and copper.

Q:How do you prevent galvanic corrosion when using aluminum sheets with other metals?
To prevent galvanic corrosion when using aluminum sheets with other metals, there are several measures that can be taken: 1. Use a protective coating: Applying a protective coating, such as paint or anodizing, on the aluminum surface can create a barrier between the aluminum and other metals, preventing direct contact and reducing the risk of galvanic corrosion. 2. Insulate the metals: Placing a non-conductive insulating material, such as rubber or plastic, between the aluminum and other metals can help isolate them and prevent galvanic corrosion. 3. Choose compatible metals: Selecting metals that are less prone to galvanic corrosion when in contact with aluminum can reduce the risk. For example, stainless steel, titanium, or other corrosion-resistant alloys are often preferred when working with aluminum sheets. 4. Use dielectric materials: Inserting a dielectric material, such as nylon or Teflon washers, between the aluminum and other metals can act as a barrier and inhibit the flow of electrical current, thereby preventing galvanic corrosion. 5. Control the environment: Avoiding environments with high moisture levels or extreme temperature variations can help reduce the likelihood of galvanic corrosion. Proper ventilation and moisture control can also play a significant role in preventing this type of corrosion. It is important to note that the best preventive measures may vary depending on the specific application and the types of metals involved. Consulting with a materials engineer or corrosion specialist can provide valuable guidance in selecting the most appropriate strategies to prevent galvanic corrosion in a particular scenario.
Q:It seemed in my experiment that aluminum wasn't reactive at all in the displacement reactions, except with copper sulfate. Is there a reason? or did I make a mistake? aluminum is more reactive than e.g silver nitrate, why didn't it react with it?
Aluminium has a protective coating of Aluminium Oxide, this prevents many chemicals reaching the surface. This is because aluminium has a very strong affinity for oxygen and bonds to it with extremely strong bonds. It can be removed by dipping it carefully into a solution of Mercury (II) Chloride.
