Product Description:

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:How much is the rust-proof and thermal insulation aluminum coil?
3003 alumal alloy is the best and common rust-proof and thermal insulation aluminum coil. The price depends on the thickness and width you need.
Q:How does Aluminium and Oxygen bond?
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:Is it safe to bake with aluminum foil?
Perfectly safe. I think you must be referring to the great aluminum pots and pans debacle Whereupon, several researchers found trace amounts of aluminum in the brains of dead alzheimer patients so, ergo, ipso, facto, aluminum causes alzheimers and everyone tossed their aluminum cookware. It was subsequently found to be the testing lab, who was finding the trace amounts of aluminum in the brain tissue, that was responsible for tainting their own equipment with trace aluminum, thus, they were finding it in EVERYTHING they tested. I still think it was the aluminum cookware industries way of getting us all to buy new pans LOL.
Q:Aluminum coil area, with aluminum sheet area, how is not the same?
Direct measurement length and width calculation area of aluminium plate;The aluminum coil can measure the volume of the aluminum coil and then calculate the area by dividing the thickness. You can also measure the mean diameter, calculate the perimeter, multiply the number of laps, the width, and calculate the area.
Q:Is aluminum silicate roll felt the same as aluminum silicate acupuncture blanket?
No, the unit weight of aluminum silicate fiber felt is greater than that of aluminum silicate acupuncture blanket. Both are thermal insulation and fire-proof material and have the same function.
Q:why does hf acid sometimes turn aluminum black?
Acid is a slow burn on some metals, aluminum tends to turn black when burned where iron turns red when it rusts or burns. I'd say the hf acid left some slight burn marks on your rails.
Q:Four roller rolling mill roller bearing on the aluminum top how always have holes
Do not know your factory function division, should have special polishing work roll, support roller grinding workshop, this problem should be addressed to them, sticks are not qualified, how can dry out qualified products?
Q:Calculate the resistance of aluminium cable of length 1o km and diameter 2mm?
Let ρ be the resistivity of the aluminum cable, A the cross sectional area of the cable and l the cable's length. The resistance R of the aluminum cable is now given by: R = ρ·l / A = 2.7·10^-8·(10·10^3) / (π·r²) = 2.7·10^-8·(10·10^3) / (π·(1·10^-3)²) = 85.9 Ω I guess the tricky part is remembering: R = ρ·l / A but when you realize how intuitive this equation is you don't have to memorize it. The resistance R is proportional to the resistivity ρ, so we must have the following in our equation: R = ρ·k , where k is some value governed by the dimensions of the cable! It is logical that the resistance is also proportional to the wires length l. This is logical when you realize that the longer the wire the more obstacles the electrons will have to pass by! Now we have that: R = ρ·l·c , where c is another value governed now by the cross sectional area (only dimensional property left). If we think of the wire as a highway with cars instead of electrons we realize that there is less resistance (higher speed) when the highway has many lanes and is very broad. From this we realize that the greater the cross sectional area the smaller the resistance. R must therefore be inversely proportional to A. We now have: R = ρ·l / A I hope there are no mistakes here :P
Q:Aluminum Frame M1911 question...?
Well you have to take your pick from two solutions: One get a steel frame which is heavier but stronger and can handle higher pressure loads, or an aluminum which is lighter but of a lower strength. What loads are you putting through it, how much are you using it, basic things like that. If you are constantly going to be shooting high powered loads through it, go with steel, if you are only going to use it as a race gun, still go with steel, aluminum is crap it deforms and decreases accuracy and jams much more often then steel.
Q:how is aluminum formed?
I don't think any significant quantity of aluminum is produced by reduction with carbon - aluminum is too reactive for this to give a good yield. Instead, the metal is produced by electrolysis in the Hall-Heroult process. First, aluminum ore is processed to aluminum oxide in the Bayer process. This ore, bauxite, consists of aluminum oxides and hydroxides with some impurities, mostly iron oxides. The aluminum oxide/hydroxides are dissolved with concentrated sodium hydroxide in water. Iron oxides and hydroxides do not dissolve, and are filtered out. AlOOH (insoluble in water) + NaOH + H2O ----- NaAl(OH)4 (soluble in water) Neutralizing or cooling this solution will cause aluminum hydroxide to precipitate out. This is then heated strongly to drive off water and produce aluminum oxide. 2Al(OH)3 ----- Al2O3 + 3H2O This aluminum oxide can be melted and then electrolyzed to make the metal and oxygen gas. However, the melting point of aluminum oxide is very high, so it is dissolved in molten cryolite (Na3AlF6), which has a lower melting point. This is then electrolyzed, and molten aluminum collects at the bottom of the cell (cathode), where it can be drawn off. Because the oxygen that would be formed will attack most metal electrodes, a sacrificial carbon electrode is used for the anode and is oxidized to CO2. Very small amounts of aluminum metal occur in nature - it is usually found in association with fossil fuel deposits (which provide the reduced carbon necessary to reduce aluminum minerals).
