The symbol warns that the material is corrosive - that it will either eat through your skin (painful) or it will dissolve steel or aluminum.
Aluminum is less dense than steel, so has less mass per volume to absorb heat energy. For the same amount of heat energy put into the same volume of aluminum and steel, the aluminum will increase in temperature faster since there is less mass to heat up. This is also known as thermal inertia. Aluminum has less thermal inertia than steel.
Salt water can be considered as a catalyst in the reaction of forming aluminium oxide.
Aluminum does react with fluorine gas (which is the most corrosive substance known to science).
steel
yes. It is
No, stainless steel never corrodes.

The aluminum door is lighter and less expensive than steel door.

Steel. It's a much stronger and much less expensive material.
Steel and aluminum are rather neck and neck with quality. Both can be coated to prevent corrosion. In the end, price is where they differ with steel being the slightly less expensive option.
made of non-corrosive aluminum
steel sure.
Steel. The density of steel is almost 3 times that of aluminum.
Salt water can be considered as a catalyst in the reaction of forming aluminium oxide.
A corrosive symbol on a product label indicates that the product is a corrosive material that could, depending on how corrosive it is, corrode steel or aluminum, or damage skin or other body tissue it may come in contact with. Usually, when we say "contact" we are talking about the skin being in contact with the corrosive liquid. However, vapors from a corrosive liquid can irritate the nose, lungs and eyes. In some cases the vapors of a corrosive liquid can be severely irritating and a hazard in themselves.
