In the field of metal materials, 5052 and 3003 aluminum plates are two common alloy aluminum plates, each with unique characteristics and a wide range of applications. Although both are widely used aluminum plates in the market, they differ significantly in chemical composition, mechanical properties, common standards, scope of application and price.

1) Chemical composition

● 3003 aluminum sheet
3003 aluminum plate is an aluminum-manganese alloy, with manganese as the main alloying element. This alloy has a relatively high aluminum content and contains small amounts of impurity elements such as silicon, iron, copper, zinc and titanium. Specifically, the manganese content is between 1.0% and 1.5%, while the copper content is between 0.05% and 0.20%. This alloy is popular for its good corrosion resistance and formability.

● 5052 aluminum plate
5052 aluminum plate is an aluminum-magnesium alloy, with magnesium as the main alloying element. Compared with 3003 aluminum sheet, 5052 aluminum sheet has a slightly lower aluminum content, but its magnesium content is higher, which makes it have superior mechanical properties and corrosion resistance. 5052 aluminum sheet also contains a small amount of chromium, zinc, manganese and other elements, the presence of these elements further enhances its comprehensive performance.

2) Mechanical properties

● 3003 aluminum sheet
The mechanical properties of 3003 aluminum sheet are relatively moderate, suitable for some application scenarios with low strength requirements. For example, the tensile strength of 3003H24 aluminum sheet is between 145-195MPa and the elongation strength is 115MPa. Although its strength is not as good as some high-strength alloys, its good plasticity and machinability make it an ideal choice for many decoration and light industrial fields.

● 5052 aluminum sheet
In contrast, 5052 aluminum sheet performs well in mechanical properties. The tensile strength of 5052H24 aluminum sheet is as high as 230-280MPa, and the elongation strength also reaches 150MPa. These superior properties make 5052 aluminum sheet have significant advantages in applications that require higher strength and corrosion resistance, such as automobiles, aircraft fuel tanks, oil pipes, etc.

3) Common standards and scope of application

● 3003 aluminum sheet
3003 aluminum sheet is usually mainly thin, and the application of thick plate is relatively small. It is mainly used in product packaging, refrigerators, air conditioners, cold storage, ventilation ducts and other fields in humid environments. Its good corrosion resistance and formability make it an ideal choice for these fields.

● 5052 aluminum sheet
5052 aluminum sheet is not only suitable for thin plates, but also for thick plates. It is often used in high-strength and high-corrosion-resistant occasions such as electrical housings, transportation vehicles, and pressure vessels. Due to its excellent mechanical properties and corrosion resistance, 5052 aluminum sheet is a common material for making automobiles, aircraft fuel tanks, oil pipes and other parts.

4) Price

In terms of price, the price of 3003 aluminum sheet is slightly higher than that of pure aluminum sheet, but it is more economical than 5052 aluminum sheet. According to different standards and thicknesses, the price of one ton of 5052 aluminum plate is usually about 2,000-3,000 yuan higher than that of one ton of 3003 aluminum plate. This price difference reflects the difference in performance and application areas between the two.

4) Summary

There are significant differences between 5052 aluminum plate and 3003 aluminum plate in terms of chemical composition, mechanical properties, common standards, scope of application and price. 5052 aluminum plate is known for its high strength, high corrosion resistance and wide range of applications, while 3003 aluminum plate occupies a place in specific fields with its moderate mechanical properties and good economy. When choosing aluminum plate, comprehensive consideration should be made based on specific application requirements and budget.
