If the bicycles are otherwise comparable, you'll burn the same amount of calories.
If the steel bike is heavier, you'll burn a few more calories on that one.
Steel typically has higher density compared to aluminum. Steel has a density of around 7.85 g/cm3, while aluminum has a density of about 2.70 g/cm3. This means that steel is heavier for the same volume compared to aluminum.
Stainless steel would last you much longer than aluminum. Aluminum is not as dense as steel, and may not last as long.
Aluminum would be better at keeping the temperatures lower compared to steel.
it wouldn't be magnet to a aluminum nail because the aluminum is not a way of magnet and a steel nail would because steel is a way of magnet.
You can use a large magnet. Aluminum isn't magnetic, but steel is... Try that out. You should write A for Aluminum and S for steel on the cans so you don't get mixed up.
steel, as it is an alloy of iron
aluminum because it has a lower density which makes it lighter
Aluminum would be lighter weight than stainless steel.
If the wheels are steel, a magnet will stick. If aluminum, it will not.If the wheels are steel, a magnet will stick. If aluminum, it will not.
Steel - strength Aluminum - light weight
They are NOT steel. Trust me when I tell you they are made of aluminum. Even the biggest, strongest WWE wrestler would have a hell of a time throwing those around if they were steel. I know for a fact they are aluminum because I make them and weld aluminum all day.
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
