Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).

Q:Why is the aluminum roll upset?
Mainly in the aluminum slitting process, for various reasons, does not meet the standards and specifications of products, can be used to roll the machine from the new trimming and slitting, winding up to meet customer needs of product specifications
Q:Why is Al2O3 called Aluminum oxide instead of Aluminum (III) oxide?
aluminium is not a transitional element its atomic number is 13 while transitional elements are in d -block (A) [ atomic no. 21 to 30 ( 3d elements), (B) atomic no. 39 to 48 [ 4d elements ] (C) atomic no. 57 to 80 [ 5d elements ] so aluminium forms only one oxide Al2 O3 [ so its name is simply aluminium oxide] while transitional elements show variable valencies [ different oxidation states] so their name is given according to oxidation state ] e . g. Fe O [ iron (II) oxide i.e. ferrous oxide ] Fe2 O3 [ iron (III) oxide i. e. ferric oxide ]
Q:What's up with aluminum foil?
the oven radiates heats it up by heating it from the outside in the microwave radiates microwaves to get water, sugar, and fat moving, heating the food from the inside and the outside. since the foil has none of these the bombardment of waves has a different effect. the atomic structure of the foil burns when it gets hit with microwaves
Q:Deodorant and Aluminum ?
If there was solid proof and research that showed it was bad for you or baby while pregnant your doctor would have told you not to use it. It's a matter of debate and controversy still and has been for many years, and I'm sure it will continue to be for many years. If you are worried, you can by aluminum free anti-perspirants, I believe Tom's of Maine makes one that is very effective. Or you can use one that just contains less.
Q:Replacing aluminum windows?
If you want to replace them, I would start at a local home improvement store-- they all carry the major brands and there are tax incentives now for replacing windows.
Q:Automotive aluminum coil, using GB H22, what brand, what are the main ingredients?
5754-H22 aluminum sheet has the characteristics of medium strength, good corrosion resistance, weldability and easy processing. It is a typical alloy in Al-Mg (mg Al alloy) alloy.
Q:a sample of aluminum chloride has a mass of 37.2 g. how many aluminum ions are present?
Aluminum Chloride is simply AlCl3 So In each mole of AlCl3 there are 1 mol of Al 3 mol of Cl We know (from periodic table), 1 mol of Al weighs 26.98 g 1 mol of Cl weighs 35.47g so 1 mol of AlCl3 weighs 26.98g + 3x35.47g = 133.39 g sooo moles of AlCl3 = 37.2 g /133.39 g/mol = 0.279 mol in one mol of anything, there are 6.02 x 10 ^ 23 of that thing... so we have 0.279 mol x 6.02 x 10 ^ 23 molecules /mole = 1.68 x 10 ^ 23 And, we know one molecule of AlCl3 dissociates into one Al ion and 3 Cl ions sooo 1.68 x 10 ^ 23 AlCl3 ions dissociate into 1.68 x 10 ^ 23 Al ions so answer is 1.68 x 10 ^ 23 Al ions
Q:copper and aluminum combined in coins?
Well, there are aluminum alloys that have copper in them (although they usually have other metals also), so I don't think it would be a problem. If you're thinking of copper plated aluminum, there is the potential for a galvanic reaction (meaning like a battery cell) that could cause the coin to corrode and fall apart. It's the same problem with the current production of US cents (which are copper coated zinc).
Q:Stripping old aircraft aluminum?
Go to an automotive paint store like Sherwin Williams Auto Paints, buy a stripper for the type of paint on the aluminum. Many are epoxy or special acrylics like acry glo or jet glo paints and home paint strippers usually won't phase those paints. A methylene chloride mixed with a soap or wax carrier will work but is a hazmat item and has to be disposed of properly but it won't be corrosive to the aluminum. Dupont, Sherwin Williams, and others make the proper strippers. You might even find some at an RV or Boat supply.
Q:is a stainless steel cookware set with an aluminum core fine for cooking?
The aluminum is encased in the stainless steel, usually as a thick disk in the bottom. It is an excellent conductor of heat and holds the heat well once it gets hot. All you see is the stainless, none of the aluminum because it's between two layers of stainless in the bottom of the pots. You are right, you don't want food cooked in straight aluminum, some metal taste can transfer to certain foods. That won't happen with stainless.
