5086 vs 5083 aluminum: What is the difference?

5086 and 5083 are both aluminum alloys that are commonly used in structural applications, such as shipbuilding, marine equipment, and transportation vehicles. While these two alloys are similar in many ways, there are some differences between them.

The main difference between 5086 and 5083 aluminum is their composition. 5083 aluminum contains 4.0-4.9% magnesium, which makes it more corrosion-resistant and strong than 5086 aluminum. In contrast, 5086 aluminum contains 3.5-4.5% magnesium and a small amount of manganese, which makes it more weldable and easier to form than 5083 aluminum.

Another difference between 5086 and 5083 aluminum is their applications. 5086 aluminum is often used in applications that require high strength and corrosion resistance, such as in the construction of boats and ships, while 5083 aluminum is often used in applications that require high weldability and formability, such as in the construction of pressure vessels and tanks.

Overall, both 5086 and 5083 aluminum alloys have excellent properties that make them suitable for a wide range of applications, and the choice between them will depend on the specific needs of the project.
