aluminum is definitely safer
yes. It is
Stainless steel that is 304 grade is basically Stainless steel that is food-safe. Most stainless steel water bottles are made from 304 grade stainless steel, as well as cutlery, knives, and watches.
No; steel is an iron-carbon alloy. Stainless steel is an alloy of steel with chromium added. Stainless steel is usually 13-25% chromium (by weight).
Yes! All steel is an alloy since there is no base atom "steel". An example of a non alloy would be gold, silver, aluminum, etc. If the metal is not on the periodic chart of the elements, it is an alloy. Stainless steel is in fact defined as a steel alloy--steel itself being mostly iron (an element) with added carbon--alloyed with at least ten percent chromium by mass.
Stainless steel.
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
stainless steel
stainless is steel. aluminum is aluminum
Vacuum insulated stainless steel bottles like one from Hydro Flask [see related link "hydro flask" below] or Thermos [see related link "thermos" below] will keep them coldest.
No. Stainless Steel will resist contamination from the aluminum when they are used together.
stainless steel is magnetic
aluminum is the best, then copper then stainless steel
aluminum conducts heat better than stainless steel.
They are both pretty hard to chew, and have little nutritional value. But seriously, it depends on what the application is. Aluminum is lighter. Stainless has other advantages. Each material corrodes in ways the other does not.
No, stainless steel never corrodes.
Stainless steel would last you much longer than aluminum. Aluminum is not as dense as steel, and may not last as long.
Stainless steel is not the best conductor. The best conductor is actually aluminum.
