Aluminium 5083 vs 7075 are both common high-strength aluminum alloy materials, and they have their own characteristics and applications in different fields. The following is a detailed comparison of aluminum 5083 vs 7075:

5083 vs 7075

  1. Composition:

Aluminium 5083 belongs to Al-Mg system alloy, the main alloying element is magnesium. The aluminum content is standard % and the impurity content is low at 0.05%.

Aluminium 7075 is a cold treatment forging alloy, the main alloying element is zinc, and contains magnesium, copper, chromium and other elements.

  1. Strength:

7075 aluminum alloy is an ultra-high strength aluminum alloy with extremely high strength and hardness for applications requiring high strength, such as aerospace. 5083 aluminum alloy also has higher strength, but is slightly less strong compared to 7075 aluminum.

  1. Corrosion resistance:

5083 aluminium alloy has excellent corrosion resistance and is particularly suitable for applications in seawater environments, such as shipbuilding. While 7075 aluminum also has a certain degree of corrosion resistance, but not as good as aluminium 5083.

  1. Machinability:

5083 aluminum alloy performs better in terms of machinability, and is easy to form, weld, and machine, making it suitable for applications that require complex forming. The 7075 aluminum alloy has relatively poor machinability due to its high hardness and requires more advanced machining techniques.

  1. Areas of application:

Aluminum 5083 is widely used in the construction industry, aerospace, shipbuilding, automotive manufacturing and other fields. In the construction field, it is used for structures such as buildings and bridges in the marine environment. In the aerospace field, it is used to manufacture components such as airplane fuselages and fuel tanks. In the field of shipbuilding, it is used in the manufacture of hull structures, decks and other components.

Aluminium 7075 is mainly used in aerospace industry, mold processing, mechanical equipment and other fields. In the field of aerospace, it is used to manufacture aircraft structural parts, landing gear and other components. In the field of mold processing, it is used to manufacture various molds and fixtures.


5083 aluminium alloy have been widely used in a number of fields with its good corrosion resistance, weldability and cold workability, especially in construction, aerospace and shipbuilding, etc. 7075 aluminum alloy especially suitable for the field of high requirements for material properties, such as aerospace and mold processing with its high strength, good mechanical properties and corrosion resistance. The choice of which aluminum alloy to use depends on the specific application needs and requirements for material properties.
