- Q:My boyfriend sweats a lot and uses Mitchlum deodorant, a lot of it, under his armpits and waits til it dries to stop the sweating. I heard aluminium was bad for you, but he says natural deodorants don't work as well. What do you think?
- This is doctrine according to me, so Don't take it for absolute truth. I had a science teacher who said the aluminum in deodorant was bad for you because you have major arteries in your armpits that go to the rest of your body and it carries it there and is linked to things like alzheimers (please excuse my spelling). Then I had another teacher who said that that was complete rubbish. Aluminum is everywhere. If it was going to do that from deodorant, it would do it from a million other things. Oh, and certain deodorants work for certain people, others not so well. I actually have to switch types every once in a while because the one I use stops working. In my experience, the natural stuff doesn't work as well. So, you don't have to believe me, but you asked what I thought.
- Q:Can aluminum coils be used in the production of heat sinks?
- Yes, aluminum coils can be used in the production of heat sinks. Aluminum has excellent thermal conductivity, making it an ideal material for heat dissipation. Coiling the aluminum into a specific shape allows for increased surface area, enhancing the heat transfer capabilities of the heat sink.

- Q:I have heard that aluminum may be a contributing agent in causing Alzheimer's disease, and that if we drink from aluminum cans, that we get aluminum into our system from them. It seems like this would be pretty easy to test in a laboratory, whether or not there are aluminum particles in the contained beverage. But I have heard or read that the inside of the cans are coated with something. So is this just typical uninformed rumors from the Internets, or is there anything to it? Hate to sound rude, but I am not really interested in opinions, like Well I don't think they would sell them if... or Oh yes, I think you get lots of aluminum from it. I am only interested in facts, not gut feelings or opinions.
- I recently covered this in a materials science class I am taking. My professor is Dr. Han Choo. Most aluminum cans have a coating of epichorohydrin. This is not to keep out the aluminum from the drink, but rather it is meant to keep the drink from reacting with the can(many sodas can actually eat through metal). The reaction of the soda with the can ruins the taste which is obviously something soda companies do not want. Aluminum also does not cause Alzheimer's. The metal is considered poisonous in large quantities and the FDA restricts the amount that can be added to drugs, food, drink, etc., but scientific consensus states that there is no link between Alzheimer's disease and aluminum. As far as BPA(Bisphenol A) health concerns go, there is little evidence proving any real harm to adults. The problems are only seen in offspring of the rodents being tested with BPA. For the most part there is little concern about the negative results of BPA exposure. There has not been any clear links in humans yet either. Extensive testing is still being done and BPA might be marginally dangerous to infants, but I wouldn't worry about it too much. If you still wish to guard yourself against BPA you should be aware that BPA is used in almost all commercial plastics and can liners(bottles, canned food, food storage containers, etc.) not just in aluminum cans.
- Q:aluminium plate - 1800mm x 950mm x 1.5mmprocesses - i) sandblasting ii) polyethylene coating iii) matt blastingWhy does aluminium plate warp after the first process?How to prevent warping? Other than increasing material thickness (weight issue)
- If you can, try and get ceramic plates, they are sooooooo much better than titanium or aluminum because they don't cause as much damage to your hair. But, if you have to choose between titanium or aluminum, go with titanium. The only thing aluminum will do for your hair is fry it and give it split ends. Please don't waste your money on a straightener with alumium plates, :)
- Q:Can aluminum coils be used in the production of architectural façades?
- Aluminum coils are indeed suitable for the production of architectural façades. Façades made of aluminum are highly favored due to their durability, lightweight characteristics, and aesthetic attractiveness. By incorporating aluminum coils into façade manufacturing, customization becomes effortless, as they can be readily molded and fashioned into different designs and profiles. Moreover, aluminum exhibits resistance against corrosion, rendering it suitable for outdoor use. Furthermore, it possesses exceptional thermal and acoustic insulation properties, thereby enhancing energy efficiency and soundproofing. In conclusion, aluminum coils offer a versatile and efficient choice for the creation of architectural façades.
- Q:What are the different pre-treatment methods for aluminum coils?
- Aluminum coils can undergo various pre-treatment methods to prepare their surface for further processing or coating. These methods serve different purposes and can be chosen based on specific requirements. One pre-treatment method is degreasing, which eliminates oils or greases on the coil surface. Solvents or alkaline cleaners are used for degreasing, depending on the application's needs. Etching is another pre-treatment method that removes surface oxides or contaminants from the aluminum coils. This can be achieved through acidic solutions or mechanical techniques like sandblasting or brushing. Phosphating, a commonly used pre-treatment method, involves applying a phosphate coating to the coil surface. This coating enhances adhesion for subsequent coatings or paints and provides corrosion resistance. Conversion coating is a popular pre-treatment method that forms thin layers of inorganic compounds on the coil surface. These coatings improve adhesion for subsequent coatings or paints and offer corrosion resistance. Common conversion coatings for aluminum include chromate, chromate-free, or anodizing. To summarize, the pre-treatment methods for aluminum coils include degreasing, etching, phosphating, and conversion coating. Each method has a specific purpose in preparing the coil surface for further processing or coating, chosen based on the application's requirements.
- Q:Can aluminum coils be used for signage and display applications?
- Yes, aluminum coils can be used for signage and display applications. Aluminum is a versatile and lightweight material that is widely used in the signage industry. Aluminum coils can be easily formed into various shapes and sizes, making them suitable for a variety of signage and display applications. Aluminum coils are commonly used for outdoor signs, such as billboards, building signs, and traffic signs, due to their excellent weather resistance and durability. They can withstand harsh weather conditions, including rain, snow, and UV exposure, without rusting or fading. This makes them a reliable choice for long-lasting signage. Additionally, aluminum coils can be coated with a variety of finishes, such as paint or powder coating, to enhance their appearance and provide additional protection against corrosion. This allows for customization and branding options, making aluminum coils suitable for both functional and decorative signage. In terms of display applications, aluminum coils can be used to create exhibition stands, trade show displays, retail displays, and various other promotional materials.
