FAQ

I know aluminum has 3 valence electrons and oxygen has 7, but if anyone could explain the chemical formula to me it would be great.
You are right about aluminum having 3 valence electrons, but oxygen has 6. Oxygen wants two more to get to 8. So the ions are Al +3 and O-2. The formula is Al2O3
im taking avelox antibiotic for my thorat bacterial infection....i brought guava juice today but i think it contains magnesium or aluminum....how long after taking avelox can i drink the guava juice????
Avelox has a drug interaction with aluminum hydroxide, aluminum-magnesium hydroxide, calcium carbonate, didanosine, magnesium hydroxide, multivitamins and things that contain zinc. The specific interaction is that these may interfere with the absorption of moxifloxacin (Avelox) in your G.I. tract . Either take the Avelox either 4 hours before or take it 8 hours after ingesting these. Or do it the other way around - eat/drink things on this list 4 hours after taking the Avelox or 8 hours before taking Avelox. If you find this to be too much work, avoid all products on this list until the Avelox protocol is completed. Guavas have magnesium.
Its currently 3 AM so i can't check, but my question is:does aluminum rust slower/faster than other metals? I've basically had this bike for about 6 years, but only rid it once. Its been sitting in my backyard under a roof (safe from rain) for 6+ years. Is it safe to ride it? Also, bonus question: Does having a bike on campus make life 10x easier?
Simple all alloy including aluminium turns to talcum powder which left will go black this is when the metal is oxidising. If the black is visible then scrap anything with it on. Have rescued many old bikes so things such as cables, tyres, tubes and your chain should be replaced as these usually suffer, if you are lucky these might still work. The chain will often freeze into a memory so won't turn, if not oiled may need hacksawed off. Most old bikes will reawaken with a few new or old replacement parts, also if will start to loosen with use so check it plus the bike will be desperately dry so to avoid component failure throw as much lubricant at it till it runs out and rejects it. The bike should only be sleeping so once wakened and sorted it will be as safe as you left it, though do check your brake blocks as these can split and perish. Steel parts can be replaced with alloy or treated with Kurust which gives rust a modern black component look. Have just woken a twenty five year old bike, once rebuilt it runs like a new bike plus is now safe as it has had various items modernised, something recommended for older bikes.
just wondering if you can weld aluminum pipe to a metal pipe for a cars exuast
aluminum to steel? short answer No and you will end up with a lot of mess and splatter try J-B weld it's a product though it can be done with a certain process that I'm not familiar with I have seen the finished application but i think the aluminum is a different metal make up I have accidentally tried to weld the two together many times not realizing what the metals were use a magnet to test if its aluminum magnets wont stick to aluminum
Several industries utilize aluminum coils across various applications. Some of the main industries include the automotive sector, where aluminum coils are used in the manufacturing of vehicle bodies and parts to reduce weight and improve fuel efficiency. The construction industry also extensively uses aluminum coils for roofing, cladding, and insulation purposes due to their durability and corrosion resistance. Additionally, the aerospace industry relies on aluminum coils for aircraft construction, as they offer a lightweight yet sturdy material for structural components. Other industries such as packaging, electronics, and HVAC (heating, ventilation, and air conditioning) also make use of aluminum coils for their specific requirements.
Why does the coated aluminum coil have thickness requirement for membrane?
The purpose of coating is to protect the surface of aluminum coil and make it more aesthetic. The thickness of membrane is closely related to the keep years of products made by aluminum coil.
The typical hardness of aluminum coils can vary depending on various factors such as the alloy composition, tempering process, and intended application. Generally, aluminum coils are manufactured in a range of hardness levels to cater to different needs and requirements. Aluminum coils can be produced in different tempers, including soft, half-hard, and full-hard. Soft aluminum coils have low hardness and are more malleable, making them suitable for applications that require easy formability such as packaging and wrapping materials. Half-hard aluminum coils are moderately hardened and offer a balance between formability and strength, making them suitable for applications like roofing and siding. Full-hard aluminum coils have the highest hardness and provide excellent strength, making them ideal for applications that require structural integrity such as automotive parts and construction materials. To determine the specific hardness of aluminum coils, various testing methods such as Rockwell hardness, Vickers hardness, or Brinell hardness can be employed. These tests measure the resistance of the aluminum surface to indentation and provide a numerical value that indicates the material's hardness. However, it is essential to consult the manufacturer or supplier for specific hardness values as it can vary depending on the specific alloy and temper of the aluminum coil.
Besides replacing all the aluminum wiring.
Aluminum wire, in and of itself, is not the hazard. You can buy receptacles that are rated for AL/CU Aluminum and copper. If the wire is intact, replace the receptacle with an AL/CU rated receptacle, and be extra careful how much torque you put on the screws that hold the wire down. AN AL/CU rated receptacle costs around $3.50 compares to the cheap $0.59 copper only rated junkers at Home Depot? You do NOT have to replace all the aluminum wiring. In other cases, you can couple AL to CU wire with approved Wire Nuts that are rated for AL/CU. BE EXTRA CAREFUL ABOUT BEND RADIUS AND TORQUE SPECS!
