5xxx Aluminum Coil/Sheet

5xxx aluminum coil/sheet refers to the aluminum alloy series containing 3-5% magnesium. The most common alloy in this series is 5052, followed by 5083, 5086, 5182, and 5454.

The 5xxx series of aluminum alloys have excellent corrosion resistance, high strength, and good formability, making them suitable for a wide range of applications, including marine, automotive, and aerospace industries, as well as in construction and architecture.

5052 aluminum is the most commonly used alloy in the 5xxx series, and it has good corrosion resistance, high fatigue strength, and moderate strength. It is commonly used for sheet metal fabrication, fuel tanks, and other marine and automotive applications.

5083 aluminum has higher strength and better corrosion resistance than 5052, making it suitable for marine and offshore applications. It is often used in shipbuilding, boat hulls, and other marine structures.

5086 aluminum is similar to 5083 in its properties, but it has higher strength and better weldability. It is commonly used for pressure vessels and storage tanks.

5182 aluminum is a strong alloy with good formability, making it suitable for can lid and tab stock, as well as for automotive body panels.

5454 aluminum is a strong and corrosion-resistant alloy that is often used in the construction of pressure vessels and storage tanks, as well as in marine and offshore applications.

Application
The main ingredient of this series aluminum sheet is magnesium element and the content is between 3% and 5%. It is also called aluminum magnesium alloy.With its low density, it features high tensile strength and elongation.

With the same area of other series, the weight of this aluminum sheet is lighter. As a result, it is used in aviation, such as in the fuel tanks in airplanes.It is widely used in conventional industries.This aluminum sheet can be used in continuously casting and rolling. It can be hot rolled. As a result, it can be used in oxidation and deep processing.
