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:How are aluminum coils protected against corrosion?
Aluminum coils are protected against corrosion through various methods. One common method is the application of a protective coating or finish on the surface of the coil. This coating acts as a barrier, preventing the contact of the aluminum surface with moisture, oxygen, and other corrosive elements present in the environment. The coating can be a layer of paint, anodizing, or a specialized protective film. Another method used for protecting aluminum coils against corrosion is the process of alloying. By adding small amounts of other metals such as copper or zinc to the aluminum, it enhances the corrosion resistance of the alloy. These alloyed metals create a protective oxide layer on the surface of the aluminum, which acts as a shield against corrosion. In addition to coatings and alloying, proper cleaning and maintenance of aluminum coils are crucial for preventing corrosion. Regular cleaning helps remove any contaminants or corrosive substances that may have accumulated on the surface of the coils. This ensures that the protective coatings or oxide layers remain intact and effective in preventing corrosion. Furthermore, proper installation and sealing of aluminum coils are essential to protect them against corrosion. Effective sealing prevents moisture or other corrosive agents from entering the coil's interior, which can lead to corrosion over time. Overall, a combination of protective coatings, alloying, regular cleaning, and proper installation techniques play a vital role in safeguarding aluminum coils against corrosion, ensuring their longevity and optimal performance.
Q:So i like eating frozen foods like wings or bagel bites and i cook them in my toaster oven with aluminum foil under them on top of the tray. I heard using aluminum is bad for you and can get you diseases or illnesses. Is this true and should i stop using aluminum foil? i eat these frozen foods maybe 3-4 times a week
Aluminum foil melts at 660dF, hardly a temp reached by a toaster oven. For years, before microwaves, TV dinners were sold in aluminum trays.
Q:I live in blue ridge ga and have about 2,000 aluminum cans and would like to know how much I can get for them.
The price for scrap aluminum cans varies litteraly every day. Within the last year, it has been between about 28 cents and 50 cents a pound. The last price I saw for clean, flattened cans delivered to the dealer was about 42 cents. As I said, it could be a bit higher or lower than that now. There are about 30-32 cans per pound of aluminum, so your 2,000 cans probably weigh around 64 pounds and could be worth about $27, assuming there has been no big change in the price recently. But that's a delivered price. If you have to drive 10 miles each way and your truck gets 20 mpg, you will be paying for a gallon of gas. If it is 30 miles each way (60 miles total), you are looking at 3 gallons of gas, which is probably about $8, leaving you a profit of around $19, or maybe a little less. That's with some optimistic assumptions, and it doesn't include the cost of big plastic bags to carry the cans. Not very encouraging, is it? Recycling makes sense for a big city or a recycling center, where they can get thousands of cans a day. But it is hard for an individual to make any money at it. i know this is not what you wanted to hear, but I hope it is helpful anyway.
Q:Are there any health concerns associated with aluminum coils?
Yes, there are some health concerns associated with aluminum coils. Aluminum coils used in heating and cooling systems can release small amounts of aluminum particles into the air, which can be inhaled. Prolonged exposure to high levels of aluminum particles may potentially have negative effects on respiratory health and could contribute to the development of lung diseases. However, the health risks are generally low and depend on various factors such as the duration and intensity of exposure. Regular maintenance and cleaning of the coils can help minimize any potential health concerns. It is advisable to consult with HVAC professionals or medical experts for specific concerns or recommendations.
Q:What is the typical heat transfer coefficient for aluminum coils?
The typical heat transfer coefficient for aluminum coils depends on various factors such as the specific application, geometry of the coil, and the surrounding conditions. However, in general, aluminum has a relatively high thermal conductivity, making it an efficient conductor of heat. For forced convection applications, where a fluid such as air or water is used to transfer heat, the heat transfer coefficient for aluminum coils can range from 10 to 100 W/m^2K. This range is influenced by factors such as the flow rate, velocity, and temperature difference between the coil and the fluid. In natural convection scenarios, where heat transfer occurs due to the buoyancy-driven flow of air, the heat transfer coefficient for aluminum coils is typically lower, ranging from 5 to 25 W/m^2K. This lower coefficient is due to the slower movement of air and the reduced heat transfer effectiveness compared to forced convection. It is important to note that these values are general guidelines and can vary significantly depending on specific design considerations, material properties, and operating conditions. Therefore, it is recommended to consult specific heat transfer data or conduct detailed experiments or simulations to determine the precise heat transfer coefficient for a given aluminum coil application.
Q:Hi,I am fairly new to design and have been doing technical drawing for only a few months. We have an item, that supports up to about 800KG of weight, as a C shaped channel. We are currently making this out of 3mm Mild Steel. Due to a new design, we are changing this design to avoid welding and painting the above part. This means we will be making the part from Galv sheet.I would like to make the part from Aluminium because 1) There will be no rust, 2) I think it will look better than Galv sheet but I need to keep the cost down.We use 3mm mild at the moment, because it is easier to weld than 2mm, not for strength really.Therefore, my question is, in everybody's opinion, would it be OK to make it from 2mm Aluminium, or is this likly to end in disaster?FYI, the part is 1600mm long, then on each long side there are presses of up 250mm, down 80mm and down 20mm. The weight is supported at 4 points on the 80mm flanges.What a question for my first go Answers! TIA
Aluminium is expensive as far as I know. I would do the costing on the aluminium first. Also aluminium is a little weaker so you'll need a thicker sheet. I would go with galvanised.
Q:Some makes like KIA make a point of having aluminum engines. I thought this was for weight, but was more prone to failure, especially in a high mileage car.
Aluminum is touchy with heat, in comparison to steel. Generally the cylinder sleeves and berring surfaces are steel lined for durability. If you have a good radiator and thermostat, there is no reason the aluminum engine will not last 200,000 miles or more.
