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:Opinions wanted. Carbon or Aluminum?
If you're going to get carbon, get a high-end frame....either as a complete bike or one that you build up with possibly non-top-level parts if you're concerned about money. I prefer aluminum for mountain bikes, steel for jump/urban bikes, and carbon for the road. A good aluminum road frame is still nice to ride but carbon is really sweet on pavement. Well-made carbon will minimize flex in the wrong areas, but leave enough compliance to give it a nice road feel. Well-made aluminum will always be a bit harsh on a road bike but can be made darn close to the same light finish weights of carbon, especially if you choose a scandium frame. The disadvantage of carbon is its relative fragility. If they get damaged beyond superficial scratches, they're destined for the lightweight and expensive dumpster most of the time. It's possible to repair damage to carbon, but the repairs are so expensive it's usually not even worth it. Aluminum can be repaired more often, but they're often trash, too.....depends on the frame. Don't rule out titanium from the mix unless you have something against it. Not as many offerings in the marketplace, but that's mainly due to it's expense and the training involved in working with it. Titanium rides are pretty sweet. Hope this helps....enjoy the new bike whatever you get. :o)
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:What happened to the aluminum coil coming out of the annealing furnace?
There is oil on the aluminum coil and the annealing time is too long.
Q:Elements that bond well with aluminium?
Yes it will be a covalent bond. The simplest compound will be CH4 where each of the electron from the four H will be shared with one each from C to provide 4 covalent bonds.
Q:Is aluminum veneer the same as color coated aluminum coil?
In general, the molded product will be painted by special spraying factory according to customer’s needs. Color coated aluminum coil is more popular in ceiling.
Q:Why there is arc panel after aluminum coil straightening?
The aluminum coil can only become flat and straight after being planished on stretch bender.
Q:What is the purpose of aluminum in injections?
Dietary okorder.com
Q:what is the california recycling refund on aluminum blocks, and scrap aluminum??
WOW.......they must be worth sum money. Lucky you!!!!!!
Q:Will anodized aluminum rust? Should I oil the exterior of my AR-15 to prevent rust?
Aluminium does not rust. The anodized finish protects the aluminium from oxidization. So no, oiling the finish is not necessary.
Q:How heavy and long is the aluminum rolling on average?
The blank aluminum coil of aluminum manufacturer is about 5-6 tons, while the aluminum coil of dealer or supplier depends on the feeding frame, about 1.5-2 tons or 3 tons.
