In the wide application of aluminum products, 1100 aluminum plate and 5052 aluminum plate are two common materials, each of which has unique chemical composition, mechanical properties and applicable fields.

1) Chemical composition

● 1100 aluminum plate belongs to industrial pure aluminum, and its aluminum content (mass fraction) is as high as 99.00%. Due to its high purity, this aluminum plate does not contain significant amounts of other alloying elements such as magnesium, silicon, copper, etc. Therefore, it cannot be strengthened by heat treatment, but retains aluminum's inherent high corrosion resistance, electrical and thermal conductivity.

● In contrast, 5052 aluminum plate is a representative of aluminum-magnesium alloy, in which the aluminum content is about 96%, the magnesium content is between 2.2% and 2.8%, and it also contains small amounts of silicon, copper, iron and other elements. The addition of magnesium significantly improves the strength, fatigue resistance, plasticity and corrosion resistance of the alloy. This alloy is hailed by the industry as a "promising aluminum alloy" and has wide applications in high-tech fields.

2) Mechanical properties

●  1100 aluminum plate has excellent ductility, formability and weldability due to its high purity. Although its strength is relatively low, its good plasticity and corrosion resistance make it excellent in some specific applications. For example, it is commonly used in food and chemical handling and storage equipment, sheet metal products, welded assemblies, etc. These applications often require materials with good formability and high corrosion resistance, but do not require extremely high strength.

●  5052 aluminum plate is famous for its high strength, good fatigue resistance, high plasticity and corrosion resistance. Its mechanical properties are much higher than those of 1100 aluminum plate, mainly due to the addition of magnesium. In addition, 5052 aluminum plate also has good weldability and can be strengthened through cold treatment to further improve its performance. These characteristics make 5052 aluminum plates widely used in high-tech fields, complex environments and aerospace fields, such as auto parts, shipbuilding, aircraft fuel tanks and oil pipes, etc.

3) Application areas

● Since 1100 aluminum plate has good formability and high corrosion resistance, it is usually used in situations where strength is not required. For example, in the food and chemical industries, it is often used as a material for handling and storage equipment; in the field of metal processing, it is suitable for making various sheet metal products and welding assemblies. In addition, 1100 aluminum plates are often used to make decorative parts such as reflectors and nameplates.

●  5052 aluminum plate is widely used in fields requiring high-performance materials due to its high strength, fatigue resistance and good weldability. In the aerospace field, it is often used to make key components such as aircraft fuel tanks and oil pipes; in automobile and shipbuilding, it also plays an important role and is used to make various structural parts and thin plate parts. In addition, 5052 aluminum plates are also widely used in the manufacture of electrical appliances, instruments, street light brackets, etc.

4) Conclusion

There are significant differences between 1100 aluminum plate and 5052 aluminum plate in terms of chemical composition, mechanical properties and application fields. 1100 aluminum plate is famous for its high purity, good formability and corrosion resistance, and is suitable for occasions that do not require high strength but have high requirements for formability and corrosion resistance; while 5052 aluminum plate is known for its high strength, Fatigue resistance and good weldability are widely used in high-tech fields and complex environments. When selecting aluminum plate materials, comprehensive considerations should be made based on specific application scenarios and needs.
