Does Zinc Rust?

You may have heard of rusting iron and steel, but does zinc metal rust? It’s a common question that many people have when it comes to metal corrosion. This blog post will cover the answer and explore how zinc can corrode.

Zinc is a metal naturally resistant to corrosion due to its chemical composition. This means that zinc metal won’t rust in most cases, even if it’s left outdoors or exposed to moisture. However, there are some circumstances in which zinc can corrode.

One of the main reasons why zinc corrosion occurs is because it’s exposed to certain elements such as sulfuric acid or chloride salts. These elements break down the protective layer that prevents corrosion and causes chemical reactions on the surface of the zinc metal. Additionally, if there’s an electrical current running through the zinc, this can also cause corrosion due to electrolysis or electrochemical reactions between metals in contact with each other.

Another factor that increases the likelihood of zinc corrosion is direct contact with other metals like copper or steel. When different types of metals come into contact with one another, they create a galvanic cell which produces an electrical charge that can cause one metal to corrode faster than another. Therefore, if you have two different types of metal in direct contact, one will be more likely to corrode than the other, depending on their relative positions in the galvanic series chart.


To sum up, while zinc is naturally resistant to corrosion and rusting in most cases, there are certain circumstances where it can corrode faster than other metals, such as when it’s exposed to certain elements or comes into direct contact with other metals. If you want your metallic items made out of zinc metal to remain free from rust for as long as possible, then make sure you take precautions against these potential causes of corrosion and rusting.
