Corrosion vs. Rusting: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
Corrosion is the deterioration of materials due to chemical reactions; rusting is the corrosion of iron and its alloys.

Key Differences

Corrosion is a broad term referring to the degradation of any material because of the reaction with its environment. This can occur to metals, polymers, and ceramics. Rusting, on the other hand, specifically relates to iron or its alloys undergoing corrosion.

As such, all rusting is corrosion, but not all corrosion is rusting. Corrosion can be due to various factors such as chemical exposure, galvanic reactions, and even microbial activity. Rusting, being a type of corrosion, is caused by the oxidation of iron in the presence of water and air.

The products formed during the rusting process are typically reddish-brown iron oxides. However, corrosion products can vary in color and composition depending on the material and the environmental factors it's exposed to.
