Question

steel is an alloy of iron and aluminium​

Answer 1

Explanation:

Alloys. An alloy is a mixture of two or more elements , where at least one element is a metal. ... Steel is an alloy of iron with carbon, but other elements may also be added to change its properties. Alloys are useful because the properties of the alloy are different from the properties of the elements they are made from.

Answer 2

Answer:

yes

Steel is useful because it is strong and cheap. But it is also heavy.

An alloy of iron, aluminium and carbon (steel's other essential ingredient) is too brittle to be useful.

Adding manganese helps a bit, but not enough for aluminium-steel to be used in vehicles.
