Product Description:

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:Aluminum roll width 750mm, single layer thickness 6.5mm, diameter 400mm., how to calculate the weight of the aluminum roll?
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:What is a good replacement for aluminum food containers?
Maybe you could look into recyclable paper containers such as those that pizza places use? I'm always a big fan of materials like pyrex glass containers as they're reusable, strong, and can be returned to the company and sterilized.
Q:aluminum bar resistance in physics?
Resistance equals resistivity times length divided by cross-sectional area. R = ρ∙l/A The resistivities at 20°C are aluminum ρ = 2.82×10⁻⁸Ωm copper ρ = 1.72×10⁻⁸Ωm So the aluminum bar with rectangular cross section has a resistance of R = ρ∙l/(a∙b) = 2.82×10⁻⁸Ωm ∙ 3.8m / (0.01m ∙ 0.05m) = 2.1432×10⁻⁴Ω The resistance of copper wire with circular cross section is given by R = ρ∙l/(π∙d²/4) = 4∙ρ∙l/(π∙d²) Hence a wire of same resistance as the aluminum bar has a length of l = R∙π∙d² / (4∙ρ) = 2.1432×10⁻⁴Ω ∙ π ∙ (0.0015m)² / (4∙1.72×10⁻⁸Ωm) = 0.0220m = 2.2cm
Q:Opinions wanted. Carbon or Aluminum?
carbon is normally lighter but i would prefer the high end aluminum
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).
Q:Pillar vs. aluminum bed stocks?
The flex around the barrel is OK. The pillar bedding and aluminum bedding both perform the same functions, it's just the aluminum frames spread the support out more broadly. These changes came about with the Bean Field rifles, Kenny Jarrett and others trying to get best accuracy. The floating barrel and the composite stock are of the same ideas. To get to the next level of accuracy you should start hand loading for your rifle. If you don't want to do it you can usually find someone who might do it for you if you buy the components and the proper die if needed. I have a Browning A-Bolt that will shoot well with factory stuff, but with my reloads I get 5 shot groups I can cover with a quarter, and that is just off a sandbag not a supported bench rig. If you need better accuracy than even that you really need to put money out for truing and facing the bolt, truing the action, etc. So, I'm thinking you have a very good stock now, changing it isn't going to gain you much, but looking at loading and truing would make more impact, especially the loading and adjusting the Cartridge Overall Length to match your specific rifle.
Q:My roll of aluminum foil was steaming?
Aluminum does not go wel in heat, in fact if left under extreme heat + pressure (A.K.A.) microwave, or toast oven, it will explode, there will be nothing left but tiny fragments of aluminum tinfoil.
Q:aluminum, iodine and water?
This Site Might Help You. RE: aluminum, iodine and water? What exactly happens in the reaction involving powdered aluminum and crushed iodine? I know that adding a few drops of water produces a lot of purple smoke and that it will flare up but what is the chemistry involved? And also, I know that the white residual left in the cup is Al2I6 but why is it...
Q:Does aluminium foil promote or stop waves?
You can use aluminum foil to build a reflector to make a Wi-Fi router directional, and increase its range. You can also use it for electromagnetic shielding. Design matters.
Q:On the 4 roller aluminium rolling mill, there will always be dents and pressing pits on the backup roll 10
For a few days and roll crushed?Whether or not the work roll tilt and the positive and negative camber of the roll are controlled, the work roll is running abnormally, and the backup roller is rubbed.
