It depends on multiple factors, There are multiple grades/alloys of both that have different characteristics ( flexibility, temperature ranges, chemical resistance that affect it's strength).
If you are going by volume, comparing pieces of the same width/length/thickness, than steel is always stronger. If your comparing by weight, comparing 2 pieces that weight the same, than aluminum is almost always stronger with the exception of chromoly steel. 41xx grade chromoly steel is the only steel that is stronger/weight than aluminum alloys(debatable), but most agree that the aluminum of similar weight will be stiffer. Aluminum alloys usually show a 1/3 weight saving with equal strength vs. non Chromoly steels, like that used in production cars. All commercial planes are made of aluminum alloy.

∙ 8y agoWhike aluminum is generally not as strong as steel recent studies and experiments have ideneit=fied a process where an alumni alloy (aluminum 7075 which contains small percentages of magnesium and zinc) is compressed with a force of about 60,000 kilograms per square centimeter while rotating it. The compressed alloy is allowed to age for month after this process.,The treated metal attained a strength of 1 gigapascal (see article Nature Communications) which is equal to some of the strongest steels and more than three times higher than conventional aluminum.

What is the name of the aluminium alloy that is almost as strong as steel?
duralumin, copper is added to the aliminium to make duralumin
Which element is strong and lightweight?
Aluminium
Does steel wire or aluminium wire stretch more after exceeding its elastic limit?
Steel
Why is steel a better choice than another metal such as aluminium or lead?
Steel is sometimes a better choice due to it's strength. However aluminium and lead are sometimes better than steel in specialised applications.
Is aluminium transmission lines reinforced with steel cable?
Yes, aluminium's tensile strength isn't high enough to suspend its own weight, so a steel-wire core is used.
What is the name of the aluminium alloy that is almost as strong as steel?
duralumin, copper is added to the aliminium to make duralumin
Why is steel so strong?
Probably because steel is made of several different metals that may make it's structure stronger than most metals.
Why do they make window frames from aluminium and not steel?
Window frames used to be made from steel but aluminium is lighter and does not rust.
What is the properties and is uses of copper aluminium iron and steel?
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.
What are the advantages or disadvantages of steel vs aluminium cars?
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.
How do stainless steel and aluminium react similarly in air?
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.
What is higher in cost galvanised or aluminium steel?
aluminum steel
How can you tell the difference between steel and aluminium?
steel rusts
What are bicycle brakes made of?
Usually an aluminum alloy, although high-end ones may be of titanium.
Why steel is used for cooking vessels?
Steel is hard and cannot be wrapped easily. Weight of steel is more than aluminium foil. Aluminium foil is rust-free.
What properties do aluminium and titanium have that make them useful material?
They're strong but don't weight much. That's why they use them in space shuttles instead of steel.
Which is stronger Aluminium or steel?
if i had to take a guess i would say steel.
