What grades of aluminum are used for solid plates?

May 14, 2025

When it comes to solid aluminum plates, the choice of aluminum grade is crucial as it directly impacts the performance, durability, and suitability for various applications. As a reliable Aluminum Solid Plate supplier, I understand the importance of providing high - quality products with the right aluminum grades. In this blog, I will explore the different grades of aluminum commonly used for solid plates and their unique characteristics.

1. 1xxx Series Aluminum

The 1xxx series is pure aluminum, with a minimum aluminum content of 99%. The most common grades in this series used for solid plates are 1050 and 1100.

1050 Aluminum

Aluminum 1050 has an aluminum purity of 99.5%. It offers excellent corrosion resistance, especially in environments where chemical resistance is required. Due to its high purity, it has good electrical and thermal conductivity. Solid plates made from 1050 aluminum are often used in the chemical industry for equipment such as storage tanks and piping. It is also suitable for applications in the food industry because it does not contaminate food products.

1100 Aluminum

With a purity of 99.0%, 1100 aluminum is highly formable. It can be easily drawn, spun, or welded. Solid plates of 1100 aluminum are commonly used in architectural applications, such as Aluminum Profiled Cladding Sheet. The formability of 1100 allows it to be shaped into various profiles for building facades and decorative elements.

2. 3xxx Series Aluminum

The 3xxx series is alloyed with manganese, which enhances its strength while maintaining good formability. The most well - known grade in this series is 3003 aluminum.

3003 Aluminum

3003 aluminum is one of the most widely used aluminum alloys for solid plates. It has a higher strength compared to the 1xxx series. The addition of manganese improves its corrosion resistance, especially in marine environments. Solid plates made from 3003 aluminum are used in a variety of industries, including automotive, where they can be used for body panels and heat exchangers. In the construction industry, 3003 aluminum plates are used for roofing and siding due to their good durability and formability.

3. 5xxx Series Aluminum

The 5xxx series is alloyed with magnesium, which provides excellent strength and corrosion resistance, especially in marine environments. Grades 5052 and 5083 are commonly used for solid plates.

5052 Aluminum

5052 aluminum is a medium - strength alloy with excellent corrosion resistance. It has good fatigue resistance, making it suitable for applications that require repeated stress. Solid plates of 5052 aluminum are widely used in the marine industry for boat hulls, decks, and other components. It is also used in the automotive industry for fuel tanks and panels, as well as in the aerospace industry for non - structural components.

5083 Aluminum

5083 aluminum is a high - strength alloy with outstanding corrosion resistance in seawater. It is often used in marine applications where high strength and durability are required, such as shipbuilding. Solid plates of 5083 aluminum are also used in the transportation industry for railway cars and trailers due to their high strength - to - weight ratio.

4. 6xxx Series Aluminum

The 6xxx series is alloyed with magnesium and silicon, which gives it good strength, formability, and corrosion resistance. Grade 6061 is the most commonly used grade in this series for solid plates.

6061 Aluminum

6061 aluminum is a versatile alloy that combines good strength, machinability, and weldability. It can be heat - treated to further increase its strength. Solid plates made from 6061 aluminum are used in a wide range of applications, including aerospace, automotive, and construction. In the aerospace industry, 6061 aluminum plates are used for structural components. In the automotive industry, they are used for engine parts and frames. In construction, 6061 aluminum plates can be used for Colorful Aluminium Composite Panel and other decorative and structural elements.

5. 7xxx Series Aluminum

The 7xxx series is alloyed with zinc, which provides high strength. Grade 7075 is a well - known grade in this series used for solid plates.

7075 Aluminum

7075 aluminum is one of the strongest aluminum alloys available. It has excellent fatigue resistance and high strength - to - weight ratio. Solid plates of 7075 aluminum are commonly used in the aerospace industry for critical structural components such as wings and fuselages. However, it is relatively more expensive and has lower corrosion resistance compared to some other alloys, so it often requires special surface treatments.

Factors Influencing the Choice of Aluminum Grade

When selecting the appropriate aluminum grade for solid plates, several factors need to be considered:

Strength Requirements

If the application requires high strength, such as in aerospace or heavy - duty transportation, grades like 7075 or 6061 may be more suitable. For applications where moderate strength is sufficient, 3003 or 5052 may be a better choice.

Corrosion Resistance

In environments where corrosion is a concern, such as marine or chemical industries, grades with high corrosion resistance like 5052, 5083, or 1050 are preferred.

Formability

For applications that require complex shaping, such as architectural cladding, grades with good formability like 1100 or 3003 are ideal.

Cost

The cost of different aluminum grades can vary significantly. For cost - sensitive applications, grades like 1xxx or 3xxx series may be more attractive, while high - performance grades like 7075 are more expensive.
