What is the difference between 3A21 aluminum plate and 3003 aluminum plate?

3A21 aluminum plate and 3003 aluminum plate are two different aluminum plate materials, with the following differences:

1. Different chemical compositions: The main components of 3A21 aluminum plate are aluminum and manganese, while the main components of 3003 aluminum plate are aluminum, manganese, copper and other alloy components. Therefore, the performance of these two types of aluminum plates is different.

2. Different strength: 3A21 aluminum plate has higher strength and hardness than 3003 aluminum plate, but 3003 aluminum plate has better ductility. Therefore, in applications that require higher strength and hardness, 3A21 aluminum plate is more suitable; When a wider application range and better ductility performance are required, 3003 aluminum plate is more suitable.

3. Different morphology: Due to different compositions, the aluminum grains of 3A21 aluminum plate and 3003 aluminum plate are different, and their grain boundaries and orientation structures will also change, thereby affecting the physical and mechanical properties of the aluminum plate.

4. Different application fields: 3A21 aluminum plate is usually used to manufacture packaging materials for food and medicine, decorative materials, chemical containers, etc; And 3003 aluminum plates are usually used to manufacture air conditioners, refrigerators, water tanks, heat exchangers, etc.

Overall, there are some significant differences between 3A21 aluminum plate and 3003 aluminum plate, but they are both excellent aluminum plate materials with extensive applications in different fields.
