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:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
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:What is the nuclear charge for Aluminium?
ALUMINIUM ALUMINUM ARE ONE SAME ELEMENT . the nuclear charge means number of protons . the number of protons electrons are ALWAYS equal = 13 e- = p
Q:What’s the standard of tensile strength and ductility of aluminum coil 3003?
Detailed description can help resolve problems quickly. Performance and status is a related. As aluminum coil is usually semi-hard, the tensile strength is greater than or equals 150, ductility is greater than or equals 12.
Q:What is the black stuff on my Aluminum baking sheet?
Aluminum reacts to anything acid and a lot of dishwashing detergents are on the acidic end of the ph scale and that causes oxidation which is the black stuff you're getting on the towel. I use commercial aluminum baking sheets when I bake. I like their heavy weight, even browning and NO burnt cookie bottoms. Hot water and a tiny, tiny bit of dishwashing detergent works to clean them. The less you expose the sheets to acidic things, the less black stuff you have. To remove it, I just take one of those sponges with a nylon scrub pad that's safe for non-stick cookware and give it a scrub. I don't soak my baking sheets or put them in the water; I put a drop of the dishwashing soap on the sponge, work it into a foam, wash and rinse quickly. Barkeeper's Friend works well on anything the dishwashing liquid won't take off also. It's normal for the type of material it is but what you use to clean them does make the problem worse. If you don't create the black stuff, you don't have the problem.
Q:wood aluminium windows?
I would choose vinyl over aluminum, aluminum windows sweat in temp changes. We have installed vinyl windows in two different homes that we have lived in.
Q:Copper and Aluminum Initial Temperature?
Example Problem Statement: An aluminum wing on a passenger jet is 29 m long when its temperature is 29°C. At what temperature would the wing be 7 cm (0.07 m) shorter? Step 1: Write down what you know in symbolic form: The wing is made of aluminum, therefore: α = 25 x 10-6 /oC Length: l = 29 m Temperature: T1 = 29 oC Change in length: Δl = -7 cm (-0.07 m) Step 2: Write down what you don't know in symbolic form: Temperature: T2 = ? oC Step 3: Find an equation that contains what you know and what you don't know: Δl = αlΔT = αl(T2 - T1) Step 4: Solve the equation for what you don't know: Δl = αl(T2 - T1); divide both sides by αl Δl/ αl = (αl/ αl )(T2 - T1) = T2 - T1; add T1 to both sides Δl/αl + T1 = T2 - T1 + T1 = T2 Δl/ αl + T1 = T2 Step 5: Plug in (substitute) what you know and you will find out what you don't know: Δl/ αl + T1 = T2 = (-0.07 m)/( 25 x 10-6 /oC x 29 m) + 29 oC = -96.551 oC + 29 oC = -67.551 oC = -67.6 oC rounded off.
Q:Aluminum heads over Cast iron?
Good aftermarket heads will often out-flow ported factory heads right out of the box. They often have better valvesprings, retainers, valves, etc. The valvetrain is often set up to use whatever cam you specify. You can also get different combustion chamber sizes to change the compression ratio. The rule of thumb is to bump your compression ratio up 1/2 point to 1 point (9.5 to 10.5)when changing to alumium heads for a given engine setup. Aluminum sucks more heat out of the chamber, which requires a compression increase to compensate. But it isnt as easy as plopping a set of heads on. You need to carefully determine what valvetrain parts to use on the heads, what chamber size to run, will all accessories and manifolds bolt up, intake runner size, port flow data... etc. Typically its best to call the tech line of the head mfg and have a long talk with the tech engineering dude. Choosing the proper setup is the differance between a really fast car and one that can be outrun by a fat kid on a tricycle..
Q:Why do we use aluminium to produce cans? And why does it have the properties?
For soda cans, it's relatively inert, flexible enough to handle a carbonated liquid, and can be opened without tools. For food, zinc-coated iron or steel is more common. The field that helps you understand why materials have the properties they have is called physical chemistry.
Q:How heavy and long is the aluminum rolling on average?
On average it is 5 or 6 tons, and you can weigh specific ones. The length = weight/(width*thickness*density).
