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:A bit of a question for the 1911 experts roaming around here. Per-say someone, who knew their way around a 1911 built one on an aluminum frame. To top it all off, if the finished gun were to be chambered in .38 super... how long would this combination last? I've heard horror stories about aluminum frames, and then I've heard some wonderful things... this question was to see if anyone had ever thought about/done this sort of thing before. Something tells me that Aluminum + .38 super wouldn't last too long... Most informative answer gets the ten point prize as usual.
I have two concerns about using an aluminum frame for that caliber. First, and like everyone else who answered, I don't think it will stand up to the .38 Super +P for very long (and I wouldn't want to be around when it fails). Second, the reason I believe the frame will not last nearly as long as a steel or stainless (my personal suggestion) frame is that the grooves the slide fits and rides in will wear and enlarge MUCH faster than a steel or stainless frame will. This will, in my opinion, also quickly have an adverse affect on accuracy. Aluminum has it's place, but I don't think it's anywhere near this kind of firearm. On a side note, one of the other people who answered said that the aluminum will offer some corrosion resistance. This may generally be true, but salt water (like sweat) attacks aluminum significantly faster than it does steel, and stainless steel is almost non-reactive to it. If he wants a lighter gun for carry, Try an XD45. If I remember right they are rated for .45 +P, but call Springfield Armory to make sure. With the polymer frame they are much lighter than a 1911, and I have been very satisfied with the accuracy and the reliability of mine. Personally, I don't think the weight savings of the alloy frame is worth the extra care to keep from sweating on it or the much shorter lifespan the gun will likely have. If he isn't planning on carrying it, what is the point of lightening the gun? He'll feel a lot more recoil, especially if he does shoot the +P ammo.
Q:For the reaction at the anode:Al ----gt; Al3+ + 3eHowever, at the anode, oxygen are also produced and forms aluminium oxide(Al2O3) with aluminium.Are Oxygen produced by oxidation of water by electrolysis? or some reaction else?If Oxygen are produced by oxidation of water, then why it can be oxidise sinceAl ----gt; Al3+ + 3e E^0= + 1.66V2H2O ---gt; O2 + 4H+ + 4e E^0= - 1.23V(if refers to E null value) Oxygen should only be produced after all the Al have been finish oxidised.Both reaction happen at the same time? Is it possible?
Anodising is a process in which the surface of a metal is modified. In the case of anodising aluminum the layer of aluminum oxide is made thicker. This is done by placing the aluminum in a sulfuric acid solution and passing a current through it so that it serves as an anode-the current releases oxygen at the surface of the aluminum increasing the aluminum oxide. I'm pretty sure this is from the reaction of the electric charge and the sulfuric acid producing oxygen as you showed in your last reaction with water. I hope this was helpful, I'm at work and don't have my old chem books and I dont' remember all this stuff off the top of my head.
