Corrosion of Metals

Corrosion of Metals | Science Fair Projects | STEM Projects
Are you curious to find out which metal is the most resistant to corrosion? In this experiment, you will cut different metals into small pieces and immerse them in different solutions to observe which one is the most resistant to corrosion.


The hypothesis is that aluminum is the most resistant to corrosion.

Method & Materials

You will cut different metals into small pieces, immerse them in different solutions, and observe the surface of the metal after two days.
You will need 3 copper sheets, 3 aluminum sheets, 3 iron sheets, 3 zinc sheets, 12 beakers, 1200ml of tap water, 1200ml of salt water, 1200ml of lime juice mixed with water, 1 measuring cylinder, 1 piece of cloth, 1 bottle of alcohol, 1 pair of scissors, 1 ruler, and 1 black marker pen.


The experiment showed that aluminum was the most resistant to corrosion, out of the four types of metals used. It was observed that the aluminum sheet was the most resistant to rust.

Why do this project?

This science project is interesting because it tests the corrosion resistance of different metals in different solutions.

Also Consider

Experiment variations to consider include testing other metals like tin, lead, magnesium or nickel, and testing different acidic and alkaline solutions to induce corrosion in the metal samples.
