Aluminium is a relatively soft, durable, lightweight, ductileand malleable metalwith appearance ranging from silvery to dull gray, depending on the surfaceroughness. It is nonmagnetic and does not easily ignite. A fresh film ofaluminium serves as a good reflector (approximately 92%) of visible lightand an excellent reflector (as much as 98%) of medium and far infraredradiation. The yield strength of pure aluminium is 7–11 MPa,while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the densityand stiffness of steel. It is easily machined,cast, drawn and extruded.

Aluminium alloys (or aluminum alloys; see spellingdifferences) are alloysin which aluminium(Al) is the predominant metal. The typical alloying elements are copper, magnesium,manganese,silicon,tin and zinc. There are twoprincipal classifications, namely casting alloys and wrought alloys, both of which are furthersubdivided into the categories heat-treatableand non-heat-treatable. About 85% of aluminium is used for wrought products,for example rolled plate, foils and extrusions.Cast aluminium alloys yield cost-effective products due to the low meltingpoint, although they generally have lower tensile strengthsthan wrought alloys. The most important cast aluminium alloy system is Al–Si,where the high levels of silicon (4.0–13%) contribute to give good castingcharacteristics. Aluminium alloys are widely used in engineering structures andcomponents where light weight or corrosion resistance is required

Q: i have received an aluminium cooker,it's in good condition but the outside is discoloured by oil splatters.The body is round ,i have used baking soda+vineger( mix with water and boil for an hour) to clean the insides,it came off clean but outside i have no clue. used a lot of elbow grease,my hands are paining now..i have this thing for gleaming utensils ,any suggestions with homemade things,don't want to buy anything: To clean discolored aluminum you can also heat 2 teaspoons cream of tarter per quart of water. It would be best to let the cooker soak in the mixture, but that might be difficult depending on the size of your cooker. Lemon juice or lime juice should also help because they have citric acid. You could cut a lemon in half and rub the halves on the cooker, then try scrubbing with something that has some texture to it (rough sponge or steel wool). The try the vinegar or cream of tarter mixture again. Whatever you use, don't try bleach as it is highly alkaline and dissolves aluminum. This leaves copper deposits can make it turn black.

Q: What is the structure of Aluminium Chloride at 180, 192.4 (melting point) and 200 degrees celsius? When does it exist as an ionic lattice and when as a Al2Cl6 dimer?: Aluminium chloride sublimes (turns straight from a solid to a gas) at about 180°C. If it simply contained ions it would have a very high melting and boiling point because of the strong attractions between the positive and negative ions. The implication is that it when it sublimes at this relatively low temperature, it must be covalent. The dots-and-crosses diagram shows only the outer electrons.
