Question:

Aluminum water bottles or stainless steel bottles?

Which ones are healthier/safer to use and easy to clean and one the go. What is easy to use and clean and better for you? Stainless steel or aluminum, and what are the coffee mugs and cups people usually use made out of? What do you guys use daily at home and do you know what they are made up of?

Answer:

Aluminum forms a protective oxide layer that prevents it from oxidizing. It doesn't have to be anodized to protect it, the oxides form on it's own. A scratch just means more oxides will be produced. However, Aluminum is chemically reactive and there are many chemicals that will act as a catalyst to remove the oxide layer. In first year chemistry, you use mercury to see the aluminum corrode quickly. I would only consider an aluminum bottle if weight was a consideration as in hiking and then I would take care to only have water in it. Most of the metal water bottles and cups are steel, you would only find aluminum and titanium items in a specialty hiking store. Note that aluminum conducts heat, stainless steel is a poor conductor as metals go but even steel conducts heat. I use a wide brim stainless steel water bottle so it's easy to clean and some double walled steel coffee cups which are a pain to keep clean because of the finish.
Aluminium is more easier to tarnish and doesn't taste as good for many. It is more lightweight and cheaper, but the quality is usually lower. Stainless steel bottles usually have less taste of metal, and don't foster bacteria/mold as well. They do cost more, but they stay cleaner better. Coffee mugs and cups are usually made of ceramic, which are generally purified sand with glazes and what not. The plastic versions are normally made of PP (#5) plastic, which is more rigid and can withstand higher temperatures. It is a plastic, but rarely will they have chemicals that are toxic like BPA.
Stainless is more durable than aluminum. Aluminum easily corrodes, so it is anodized which is a coating on the aluminum. The coating is easily scratched to expose the bare aluminum below which starts the corrosion. Stainless develops corrosion as well, but it is only a few molecules thick and tightly bound to the surface. My coffee cups at home are ceramic, though I do have some that are glass. I have a travel cup which is constructed of stainless steel with a dual layer vacuum chamber to act exactly like a Thermos does. It has a wide base and narrow top and a big handle, which makes it sit on the dashboard nicely. No, my 1990 Geo Metro does NOT have any cup holders...
Answer to all your questions is stainless steel. Stainless steel prevents it from rusting and getting more bacteria compared to aluminum. People usually use stainless steel mugs for coffee and I too use stainless steel products for drinks.
Definitely okorder They have a large selection of stainless steel water bottles that are an alternative to plastic or lined aluminum bottles that are sustainably produced, reusable and free of BPA and other toxins. The bottles are18/8, food-grade stainless steel instead of aluminum or plastic because the metal itself is safe and toxin-free. Stainless steel is made of many elements and minerals, some of which are actually recommended by the FDA such as iron. Other components of stainless steel including manganese and chromium are often included in multivitamins and other dietary supplements.
