1-Series aluminum plates belong to the pure aluminum series. Featuring high purity, excellent electrical and thermal conductivity, as well as outstanding formability, they are widely used basic aluminum materials in industry.

3-Series aluminum plates are part of the aluminum-manganese alloy series. The addition of manganese enhances their strength and corrosion resistance. With good processability and weldability, they have a broad range of applications.

There are distinct differences in composition between 1-Series and 3-Series aluminum plates. 1-Series aluminum plates have high purity, while 3-Series aluminum plates contain manganese alloying elements, which leads to differences in their performance. In terms of mechanical properties, 1-Series aluminum plates have lower strength but good ductility, whereas 3-Series aluminum plates have higher strength and improved hardness. As a result, their application scenarios are each focused on different fields.

1-Series aluminum plates are suitable for scenarios with high requirements for electrical and thermal conductivity, such as cables and heat sinks. On the other hand, 3-Series aluminum plates are applicable to structural components that require a certain degree of strength and corrosion resistance, such as ship and vehicle parts.
