if i had to take a guess i would say steel.
Chemically, aluminium is an element, while steel is an alloy consisting mostly of iron. Although most aluminium items you see and use are also Alloys, strictly speaking. Steel is stronger but heavier. They have quite different material qualities.
Aluminium and steel cans can be separated using a magnet, as steel is magnetic while aluminium is not. By running a magnet over a pile of cans, the steel cans will be attracted to the magnet while the aluminium cans will not, allowing for easy separation.
Window frames used to be made from steel but aluminium is lighter and does not rust.
copper aluminium iron and steel is an excellent conductor of electricity and heat is one of the properties of copper aluminium iron and steel and it is used in conducting electricity.
Steel is stronger.
Aluminium has some advantages over steel. Since it has a lower density than iron or steel, a car body made from aluminium will be lighter than the same car body made from steel. This results in improved fuel economy. Also, aluminium does not corrode easily, so a car body made from aluminium will corrode less, and may last longer, than one made from steel. However, aluminium is more expensive than steel. So a car made from aluminium is likely to be more expensive than one made from steel.
neither of them corrodes. Both of them are passivated, in stainless steel it is a film of chromium oxide, in aluminium a film of aluminium oxide.
There's too much personal preference for that question to be answered. An aluminium bike has the possibility to be lighter, but a steel bike can be stronger. Pick what's more important for you.
aluminum steel
steel rusts
Steel is hard and cannot be wrapped easily. Weight of steel is more than aluminium foil. Aluminium foil is rust-free.
Yes. Actually... a diamond is NOT 'stronger' than steel. A diamond is 'harder' than steel, but it is not stronger.
