So far as durability goes, aluminum beats iron in only one category. Iron oxidizes readily...so does aluminum but, the difference is that aluminum forms an oxide layer that is impermeable to oxygen. When iron rusts, the rust offers no protection and the metal continues to oxidize. Stainless steel is an iron alloy that is protected from oxidation because the chromium in the mixture provides a protective oxide layer, like aluminum's.
They are simply different elements, look at a Periodic Table. The elements are defined by the number of protons they have. Aluminum has 13 protons, Iron has 26 protons.
A better question would be what is steel? Steel is an alloywhich contains both iron and other elements, such as aluminum.
It doesn't, really.
Iron rusts; aluminum is a "self-protecting" metal which rapidly forms a (thin, essentially transparent) protective layer, which might be what you're thinking of.
Aluminium is best because it is easily bent into shapes and melted
It takes very much more energy to convert Bauxite (aluminum ore) into aluminum metal than it does to melt iron out of iron ore. The process is much more complicated too.
Er ye watever Ryan
Because it just how life goes
Iron & Aluminium are much more abundantly found as compared to platinum.Moreover in reactivity series aluminium & iron are found to much more reactive than platinum,platinum is least reactive.
Because it was lighter, harder, and more durable than iron
Steel is more useful compared to Iron because it doesn't rust as easily and it is more durable than iron. Iron is more maleable than steel which makes steel more useful than iron.
Aluminium reacts very rapidly with the oxygen in the air to form a thin film of aluminium oxide covering the entire surface of the aluminium in the foil. This surface is invisible to the eye. Aluminium oxide is very resistant to chemical processes, like corrosion. It protects the aluminium underneath very well, so aluminium does not corrode in moist environments. If the aluminium is scratched, an new aluminium oxide film forms immediately, protecting the scratched part. Iron does not form a protective skin, because iron oxide has different chemical properties to aluminium oxide and is not able to protect the iron.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
aluminum is more durable than iron.
Enthalpy of combustion of aluminium is much more intensive than that of iron.
Iron & Aluminium are much more abundantly found as compared to platinum.Moreover in reactivity series aluminium & iron are found to much more reactive than platinum,platinum is least reactive.
is galvanised iron more corrosion ressistant than aluminium
Aluminium is more reactive than iron (Fe) according to the reactivity series of metals. Thus, when Ferrous Sulphate solution is stored in Aluminium can, Aluminium being more reactive, displaces iron from its solution to form Aluminium sulphate and iron. :)
Aluminium is lighter than steel and much more durable
Because it was lighter, harder, and more durable than iron
Iron is heavier than aluminium. Aluminium is easier to form, shape and machine.
1. iron is having more number of positively charged electrons than aluminium 2. aluminium consists of negatively charged ions in protons 3.due to convection, and gaps between atoms, the atoms vibrate and heat up quickly.
Aluminium is more expensive than iron because of its lower abundance in the Earth's crust. It is also more costly to extract and refine aluminium due to the energy-intensive process of electrolysis. Additionally, aluminium has a higher demand and is used in a wide range of industries which further contributes to its higher price.
Steel was more rust resistent and more durable.
Iron has a higher density than aluminum
