Aluminium alloys (or aluminumalloys; see spellingdifferences) are alloys in 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 tensilestrengths than wrought alloys. The most important cast aluminiumalloy system is Al–Si, where the high levels of silicon (4.0–13%)contribute to give good casting characteristics. Aluminium alloys are widelyused in engineering structures and components where light weight or corrosionresistance is required

Q:Aluminum extrusions are bars made with hollow cavities that allow each to be joined easily, using special connectors. The primary difficulty when painting aluminum extrusions centers on the fact that they are nonporous and durable. Each of these traits creates a complication of its own.: Your question supposes that you need to Paint the Aluminum Extrusion. The more common thing to do is to Anodize the extrusion. This process coats all surfaces with a hard durable coating. There are several colors available. Actually It's common to use Urethane's to paint Aluminum and the primer isn't simply made for metal, but is specifically for Aluminum. A lot of Airplanes are coated every day in this manner. Methods for coating the insides of tubing have been used for a very long time. You basically fill the tube with primer or coating then drain the excess out (dip method) and difficult shapes can be powder coated or electro static coated. Extrusions can be roller coated after cleaning, vinyls work very well with out priming. Think Toothpaste tubes.

Q:I have been reading up on thermite and the required ingredients. I have extremely fine aluminum powder from a small etch-a-sketch sitting on plastic wrap in my room. On the comments page of the site i got the thermite ingredients from, multiple people said that thermite could explose if you use too fine of a powder. I have also read that powdered aluminum can become very explosive when it is exposed to air or if it becomes damp. Ive gotten particulary worried because the humidity right now is 93%. So, is powdered aluminum too dangerous to have in house and is too fine powdered aluminum explosive when in thermite?: Powdered aluminium isn't explosive, and any humidity or dampness in the air won't affect it. Really finely powedered aluminium is nothing but an extremely powerful reducing agent. In other words, it won't explode, but it will burn very fast and very hot. When combined with magnesium powder, it contributes to the nature of thermite in a reduction-oxidation reaction. On it's own however, as long as you keep it away from any open flames, it's perfectly safe. I should say; be very, very careful with making thermite. It's not explosive on it's own, but if you make it wrong, it can fizzle and pop and send molten metal flying your way.

Q:Aluminum metal is oxidized in aqueous base with water serving as the oxidizing agent. Al(s) + H2O(1) → Al(OH)4- + H2(g) (basic solution) Write a balanced equation for this reaction in basic solution.: You need to add OH- ions on the left. 2Al + 2OH- + 6H2O ---- 2Al(OH4)- + 3H2

Q:I would like to order 25 micron diameter 99.99% Aluminum wire required to use for making electrical connections. Only several cm are needed, so I would like to purchase a small spool. Delivery ASAP preferable (overnight or two day shipping would be best). This wire will be attached by hand using epoxy and not using a wire bonder.: If they can't help, try asking the tech support guys at the wirebond manufacturers and the tool manufacturers. KS in the US and Shinkawa in Japan used to be the big guys. You can search for ultrasonic bond tools. You can also check with superconducting research centers; several private and public ones. Researchers might loan you materials and/or bonding support. BTW, Al critical temp is reportedly about 1.2°K, pretty tough to get that cold! U/S bond wire has 1% silicon, partly for hardness, you can probably bond pure wire though. Key is breaking up the oxide. Maybe bonding at cold temps and/or in vacuum would work. Also, I doubt epoxy would be good or superconducting at the temps. Al filled epoxy is unreliable electrical conductor due to oxide formation. Will be a bear to handle such fine wires without a bonder! Good luck!

Q:Can aluminum coils be fabricated or machined?: Aluminum coils have the ability to undergo fabrication or machining. They are commonly utilized in heating, ventilation, and air conditioning (HVAC) systems, automotive radiators, and electrical transformers. These coils can be tailored and machined according to specific requirements and dimensions. The fabrication of aluminum coils involves procedures such as cutting, bending, and welding in order to achieve the desired shape and size. This allows for customization and adaptation to various applications. Conversely, machining involves the removal of material from the aluminum coil through the use of cutting tools such as lathes, mills, or CNC machines. This process is employed to attain precise dimensions, smooth finishes, and intricate designs. In summary, aluminum coils possess versatility and can be fabricated or machined to accommodate diverse needs. The flexibility of aluminum as a material renders it a favored choice in numerous industries, offering durability, lightweight properties, and exceptional thermal conductivity.

Q:I want to paint my cars rims and grill metallic pink. But supposedly paint doesn't stick well to aluminum. What can I do to make it stick better and not chip?: Rustoleum. Read the directions.

Q:Can aluminum coils be used in electrical transmission systems?: Yes, aluminum coils can be used in electrical transmission systems. Aluminum is a commonly used material in electrical transmission systems due to its favorable electrical conductivity, high strength-to-weight ratio, and cost-effectiveness compared to other materials such as copper. Aluminum coils are used in transformers, motors, generators, and other electrical devices. Additionally, aluminum coils are lightweight, which makes them easier to handle and install in transmission systems.

Aluminum is a preferred material for beverage cans due to its various advantageous properties. Firstly, aluminum is lightweight, which makes it easy to transport and handle. This is particularly important for the beverage industry, where large quantities of cans are produced and distributed. Additionally, aluminum is highly malleable, allowing it to be formed into the desired shape without losing its structural integrity. This makes it ideal for can manufacturing, as it can be easily shaped into a can's cylindrical form and withstand the pressure from carbonated beverages. Moreover, aluminum is a non-toxic material, ensuring that it does not contaminate the beverages stored in the cans. It also provides a barrier against light, oxygen, and moisture, which helps to preserve the taste and quality of the beverages. Furthermore, aluminum is recyclable, making it an environmentally friendly choice for can manufacturing. The recycling process for aluminum requires significantly less energy compared to producing new aluminum, making it a sustainable material option. Overall, the suitability of aluminum coils for beverage can manufacturing is evident due to its lightweight nature, malleability, non-toxicity, preservation properties, and recyclability.

Q:What are the common surface protection methods for aluminum coils?: Various industries widely use several common methods for protecting the surface of aluminum coils. These methods aim to ensure the long-term durability and performance of the coils by preventing corrosion and other types of damage. Anodizing is one of the most common surface protection methods for aluminum coils. It involves immersing the coil in an electrolyte bath and applying an electric current to create a protective oxide layer on the surface. This oxide layer not only improves the appearance of the coil but also enhances its resistance to corrosion, scratching, and wear. Coating is another popular method for protecting the surface of aluminum coils. It involves applying a layer of paint or coating material onto the coil's surface. Coatings can be applied using various techniques, such as electrostatic spraying, roll coating, or coil coating. These coatings act as a barrier between the aluminum surface and external elements, safeguarding it from moisture, UV radiation, and other environmental factors that can cause corrosion and damage. Protective films also offer a way to protect aluminum coils. These films, typically made from polyethylene or similar materials, are applied as a temporary protective layer. They help prevent scratches, abrasions, and other types of damage during transportation, storage, and installation. When it's time to use the aluminum coil, the protective film can be easily peeled off, leaving behind a clean and undamaged surface. Proper storage and handling practices are also crucial for protecting aluminum coils. Storing the coils in a dry, clean, and well-ventilated area, away from corrosive substances, can significantly extend their lifespan. Additionally, handling the coils with care and using appropriate lifting and transportation equipment can prevent physical damage that could compromise their integrity. In conclusion, the common methods for protecting the surface of aluminum coils include anodizing, coating, the use of protective films, as well as proper storage and handling practices. By employing these methods, aluminum coils can be effectively safeguarded against corrosion, scratching, and other forms of damage, ensuring optimal performance and longevity.
