What are the differences between 5083 and 5052 aluminum plates?

From an oxidation perspective, there isn't much difference between the two; the main distinctions lie in their mechanical properties.

In terms of tensile strength and yield strength, 5083 aluminum plates are significantly stronger than 5052 aluminum plates.

Their chemical compositions are as follows:

5052: Si 0+ Fe 0.45 Cu 0.1 Mn 0.1 Mg 2.2-2.8 Cr 0.15-0.35 Zn 0.1

5083: Si 0.4 Fe 0.4 Cu 0.1 Mn 0.3-1.0 Mg 4.0-4.9 Cr 0.05-0.25 Zn 0.25

Here are their characteristics and applications:

5052 alloy aluminum plates exhibit excellent formability, corrosion resistance, weldability, and moderate static strength. They are used in the manufacture of aircraft fuel tanks, tubing, sheet metal parts for transportation vehicles, ships, instruments, streetlight brackets, rivets, and hardware products, among other applications.

5083 alloy aluminum plates are employed in situations that demand high corrosion resistance, good weldability, and moderate strength. These include welded components for ships, automotive and aircraft panels, pressure vessels with strict fire resistance requirements, refrigeration equipment, TV towers, drilling machinery, transportation equipment, missile components, armor, and more.

The 5XXX series of alloys belong to the commonly used aluminum alloy series, with magnesium as the primary element, typically comprising 3-5% magnesium. They are also known as aluminum-magnesium alloys.

Key characteristics include low density, high tensile strength, high elongation, and good fatigue strength, but they cannot be heat-treated for strengthening. Aluminum-magnesium alloys have lower weight for the same surface area compared to other series, making them widely used in conventional industries.

In China, the 5XXX series of aluminum plates are considered one of the more mature aluminum plate series.
