Suggest why aluminium is more expensive than iron?

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.

- Far more expensive than steel - Can damage easily - Weak


Why are tine cans not made out of tin?

Because tin is more expensive than aluminium.


Why is aluminum prefered to copper?

Aluminium is cost effective for products such as electric conduction,vessels that require hard and light metal.It is less reactive to corrosion while copper is expensive and now more expensive than aluminium.


Why is pure aluminium rarely used for the construction of large objects?

Pure aluminium is expensive.


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.


Why is pure aluminium oxide mixed with cryolite before electrolysis?

Pure aluminium oxide is mixed with cryolite in electrolysis of aluminium because cryolite lowers the melting point of the mixture, making the process more energy-efficient. This allows the aluminium oxide to dissolve in the molten cryolite and conduct electricity more easily, leading to the extraction of aluminium metal from the ore.


What is more cheaper aluminum or copper?

What are the different types of conductors used in transmission?

Overhead transmission lines use steel-cored stranded aluminium conductors. The steel supplies the necessary tensile strength, as aluminium is relatively weak. Copper is not generally used as it is significantly more expensive than aluminium.


Why do you need steel in concrete?

Since you're already using concrete, not much point in using the lighter, weaker, and more expensive aluminium. And lead is really weak, environmentally hazardous and more expensive than iron.
