Aluminium is a relatively soft,durable, lightweight, ductile and malleablemetalwith 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 light and an excellent reflector (asmuch as 98%) of medium and far infrared radiation. The yield strengthof pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from200 MPa to 600 MPa. Aluminium has about one-third the density and 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: Are there any health risks associated with aluminum coils?
- There are some concerns about the potential health risks associated with aluminum coils. Aluminum is a common material used in the construction of coils for air conditioning and refrigeration systems. However, when aluminum comes into contact with certain acids, such as those found in some cooling agents and cleaning solutions, it can corrode and release aluminum ions into the air. Inhaling these aluminum ions may pose health risks, particularly for individuals with respiratory conditions or allergies. Additionally, there have been reports suggesting a potential link between aluminum exposure and certain health issues, such as Alzheimer's disease and breast cancer. However, scientific research regarding this connection is inconclusive and ongoing. It is important to note that aluminum is a naturally occurring element found in many foods, water, and even the air we breathe. It is also used in various consumer products, such as cookware and food packaging. To minimize potential health risks, it is recommended to ensure proper maintenance and cleaning of air conditioning and refrigeration systems to prevent the buildup of corrosive substances. Regularly changing air filters and using appropriate cleaning solutions can help reduce the risk of aluminum corrosion. Additionally, individuals with pre-existing respiratory conditions or allergies may consider consulting with a healthcare professional to determine any specific precautions they should take.
- Q: I need to draw dot and cross diagrams to explain how they bond, but if the aluminium outer shell has 13 electrons and the oxygen one has 6, how do they all become happy atoms, and all have a full outer shell? please help! thank you.
- Aluminum's outer shell is 3, not 13. 13 is the total number of electrons it has. Looking a the periodic table, Oxygen's usual valance state is -2 as an ion. Aluminum's valance state is always +3. This means that oxygen gains 2 electrons to get a charge of -2 and aluminum lose 3 electrons to get a charge of +3. As for electron configuration, aluminum has 13 electrons in total. 2 e- is in the 1st sublevel. 8 e- is in the 2nd sublevel. That leaves 3 e- left but 3 is not a stable number so aluminum wants to lose those 3 e- to become stable. Oxygen has 8 electrons. 2 e- is in 1st. 6 e- is in 2nd. 6 is not a stable number so oxygen wants to gain 2 more e- to become a full set of 8. Aluminum want to lose 3, Oxygen want to gain 2. We need to balance those. 3 x 2 = 6 2 x 3 = 6 Because Aluminum's usual state is +3, we can have 2 Aluminum atoms bonding. If both lose 3 e-, they both have stable outer shell of 8 (2nd sublevel) and lose 6 e- in total. Oxygen's usual state is -2, but there are 6 e- to gain to oxygen can have 3 atoms bonding. If all 3 atoms receive 2 e- in each, then that's 6 and they're all stable, also at 8 e-. So in order to turn them into happy atom, we need 2 Aluminum and 3 Oxygen to bond together. So the chemical formula is Al2O3 (Aluminum Oxide) *** I'm not very good at explaining, I did the best I can. As for the drawing, I can't do that on the computer. It would have been a whole lot easier if I can though.

- Q: im doing an a level physics presentation on aluminium and im trying to compare aluminium and copper in electricity pylons.i know that copper will have a better conductance than aluminium becasue it has a lower resitivity but i need to come up with a calculation to prove why aluminium is better for use in electricity pylons? i know its down to aluminium being more lightweight than copper and also much cheaper. But im not sure how to create an calculation to show this?:) any help is greatly appreciated
- Copper has lower resistance per unit volume, ie, a 1 cm diameter copper wire has less resistance than a 1 cm aluminum wire. BUT, aluminum is much lighter than Cu for the same diameter. If you used an aluminum wire that weighs the same as the 1 cm diameter copper wire, it would have LOWER resistance. And that is why aluminum is used in power transmission, and also in aircraft, where weight is important. to do this you calculate density resistivity which is (resistivity x density). Here is a partial table: Al 28.2e-9 Ω-m * 2700 kg/m? = 76e-6 Ω-kg/m? Cu 17.2e-9 Ω-m * 8960 kg/m? = 154e-6 Ω-kg/m? Ag 15.9e-9 Ω-m * 10500 kg/m? = 167e-6 Ω-kg/m? Au 22.14e-9 Ω-m * 19300 kg/m? = 427e-6 Ω-kg/m? Zn 68e-9 Ω-m * 7130 kg/m? = 485-6 Ω-kg/m? Fe 100e-9 Ω-m * 7870 kg/m? = 787e-6 Ω-kg/m? Note that Al is half that of Cu.
