Aluminium is a relatively soft, durable, lightweight, ductileand 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 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:so i have a dirtbike and i wanted to polish the swing arm.i have 100 grit,400,800 and 1200.i use to 100 to take off the coating the swing arm has and once its off its like a natural aluminum left.well i polished it before and it came out real good to a mirror finish.well i did the other half of the swing arm exactly the same even with new sand paper and it just didnt shine like the other half!i wet sanded it and i used car wax as my buffing compound,yes i used a soft buffing wheel.the car wax works really good!thats how i got the first half to a mirror shine but the other half just wasnt working for me.any suggestions?oh and i sanded in all one direction.
- Use 1200 to 2000 grit. Your sandpaper is way too course! The paper probably got gummed up With aluminum particals. Use water or oil to wash away particals. In other words wet sand it. Then get this polish called Mothers Aluminum Polish. And two micro fiber cloths. Use the mothers and wipe off with first towel. Then use second towel. Trust me! I spend alot of time in my machine shop making custom aluminum parts. If you can trickle water over the surface of what your polishing it helps. The 1200 to 2000 grit can be purchased at Walmart in the auto section.
- Q:I have a diamond back bike with an aluminum frame. will it rust if i ride or put it in the frame? is it bad for the bike?
- sophisticated task. search onto a search engine. this can help!
- Q:Aluminum metal is oxidized in aqueous base with water serving as the oxidizing agent. Al(s) + H2O(1) → Al(OH)4- + H2(g) (basic solution) Write a balanced equation for this reaction in basic solution.
- You need to add OH- ions on the left. 2Al + 2OH- + 6H2O ---- 2Al(OH4)- + 3H2
- Q:Hi,I am fairly new to design and have been doing technical drawing for only a few months. We have an item, that supports up to about 800KG of weight, as a C shaped channel. We are currently making this out of 3mm Mild Steel. Due to a new design, we are changing this design to avoid welding and painting the above part. This means we will be making the part from Galv sheet.I would like to make the part from Aluminium because 1) There will be no rust, 2) I think it will look better than Galv sheet but I need to keep the cost down.We use 3mm mild at the moment, because it is easier to weld than 2mm, not for strength really.Therefore, my question is, in everybody's opinion, would it be OK to make it from 2mm Aluminium, or is this likly to end in disaster?FYI, the part is 1600mm long, then on each long side there are presses of up 250mm, down 80mm and down 20mm. The weight is supported at 4 points on the 80mm flanges.What a question for my first go Answers! TIA
- That is actually a complicated question that may need serious engineering. First of all, pure aluminum is rather soft and flexible and you may need to consider an aluminum alloy, perhaps an alloy used in aircraft structures to resists loads. The nature of the load (concentrated or distributed) may affect how the channel tends to bend and the strength needed to resist bending. C channels many tend to bend, shear, twist or buckle and could also fail where loads are applied or at end connections. Likely, mechanical engineers would make a freebody diagram of the channel and study its loading and physical restraints to calculate the strengths needed. Then it is likely a safety factor (10%, 50%, etc. extra strength) would be required depending upon the consequences of failure. If public safety is at issue, calculations should be performed (or checked) by a licensed professional engineer. Because channels (usually) can not be custom made at rolling mills (unless there is a huge order) the next larger available channel in the correct alluminum alloy may be required. Often insurance and product liability demand a correct solution. If the existing mild steel flange works, it (or an assembly drawing) could be presented to show the necessary configuration and help identify possible interferences if channel dimensions must change. Depending upon environment (wet, dry etc.) mixing metal parts may raise corosion concerns. For example, drainage from copper flashings on roofs tends to corode aluminum gutters. Aluminum alloy will likely be more expensive than mild steel and titanium would be stronger and lighter than aluminum (and is now being used in aircrafts) but would be even more expensive. Channel cost may be more important in a large production run than in a one of a kind structure.
- Q:Aluminum roll 220 kg.0.3 thickness, 500 width, roll diameter is how much?
- You can use the outside diameter, the inner diameter and the width to get the volume. You know the density and volume, and then you can find the weight naturally
- Q:How do I deal with too much aluminum powder when the aluminum strips are divided?
- For example, the wind speed control did not meet the requirements, or not in accordance with the explosion-proof ventilation system requirements set, including pipeline setting, setting, filter series parallel is the selection of explosion-proof, whether Mars and extinguishing measures.
- Q:What's the color coated aluminum roll?
- The so-called color coated aluminum coil, refers to the surface of Aluminum Alloy the coloring process, because Aluminum Alloy properties is very stable, not easy to be corroded, the general surface after special treatment can ensure that at least 30 years do not fade, because of its low density, high hardness, weight of unit volume of metal materials is the lightest. The color of aluminum is a new material recently emerged in the field of the plastic doors and windows, and compared, the biggest advantage is that the degree of firmness and color changing, There is nothing comparable to this, and never faced steel have always been questioned "toxic" two words. Therefore, in high-grade market doors and windows, sunshine rooms, balcony packaging and other fields are widely used. Now, color coated aluminum rolls have become one of the most popular top decorative materials. It is a kind of green with environmental protection, durability and beauty. It has the following advantages as decorative materials unmatched by other products: uniform color, bright and smooth, durable, strong adhesion, acid and alkali corrosion resistance, weathering resistance, decay resistant friction resistance, resistance to ultraviolet radiation, strong weatherability.
- Q:A certain ionic compound is made entirely of aluminum and oxygenWhat is the formula for this compound?
- Aluminium Oxide: Al2O3 The ions: Al3+ .............. O2- When they bond: It is ionic as it takes place by the transfer of electrons from Aluminium(metal) to Oxygen(Non-metal). Hence, the bond is: Al2O3, Aluminium Oxide or alumina.
- Q:Why is the hard drive made of aluminum? Why is steel not used, despite being cheaper?
- The actual disks are made from an aluminum substrate. Aluminum is the best choice for minimizing the inertia of the disk pack, which reduces the energy required to spin it. A steel pack would use much more energy. Many other materials, magnets, copper, gold, oxides, diamond like coatings, insulators are inside disk drives
- Q:They say aluminum can be found in deodorants.And this aluminum is absorbed by the skin and block pores.Does the amount of aluminum affect the rate of how it dries up?
- Aluminium zirconium tetrachlorohydrex gly, a common antiperspirant, Aluminum compounds or aluminum salts, such as aluminum oxide (Al2O3), are key ingredients in almost every antiperspirant. They are powerful astringents that close pores, THe aluminum is basically there to stop perspiration.They do not have an effect n how long the application take to dry. Deodorants work by keeping bacteria from growing that use the sweat for food long with skin cells that slough off.
