Rust forms on the exposed steel surface. Corrosion is a degradation of metal and it happens when the iron molecules of the elements react with oxygen to produce iron oxides in the presence of water. Metal can also react to harsh industrial elements. There are different types of corrosion such as crevice corrosion, intergranular corrosion, uniform corrosion, pitting corrosion, and galvanic corrosion. Corrosion can occur on various types of metal. But there are a few types of metal that do not rust. In this article, we have shared the different types of metal, how corrosion does not occur on these elements and which type of metal fence has resistance power against rust.
Types of Metal That Don’t Rust
●
Copper, brass and
bronze
●
Galvanized steel
●
Stainless steel
● Aluminum metal
Aluminum Metal
There are various tools and machines which are made from aluminum. Aluminum is not only popular for its lightweight but also for its corrosion-resistant power. Aluminum alloys have almost no iron, therefore, they can oxidize but don’t rust. If the aluminum alloy comes in contact with water, then a layer of aluminum oxide can form on the surface rapidly. The oxide layer actually protects the metal from getting rust.
Stainless Steel
Stainless steel is a combination of various types of components so it can also oxidize which protects it from rust. Keep in mind different types of metal that have 18% of chromium. The chromium oxidation creates a layer of chromium oxide on the surface of the metal. The layer prevents oxygen from reaching the underlying steel and also resists corrosion. The other elements of the steel such as molybdenum and nickel also put strength to protect it against corrosion.
Galvanized Steel
This type of carbon steel is coated with a layer of zinc and acts as a barrier to water and oxygen after completing the galvanization process. The zinc layer restrains the water and oxygen from reaching the steel. As a result, galvanized steel is also rust-free. If the layer is scratched off because of any reason, then it can even protect the surrounding areas of the underlying steel. Keep in mind that aluminum-zinc reacts to moisture and oxygen and protects the iron from oxidation.
