First, the chemical composition
The chemical composition of 1100 aluminum plate and 3003 aluminum plate is different. 1100 aluminum plate has an aluminum content of more than 99%, while 3003 aluminum plate has an aluminum content of about 98%, and also contains about 1% of manganese. Therefore, 1100 aluminum plate is more pure and performs better in terms of corrosion resistance and processability.
Second, hardness and strength
Due to the different chemical composition, the hardness and strength of 1100 aluminum plate and 3003 aluminum plate are different. 1100 aluminum plate belongs to the soft aluminum plate, has good plasticity and ductility, but the strength is lower. And 3003 aluminum plate belongs to semi-hard aluminum plate, hardness and strength is higher than 1100 aluminum plate, but plasticity and ductility is relatively poor.
Third, corrosion resistance
1100 aluminum plate and 3003 aluminum plate corrosion resistance is also different. 1100 aluminum plate has a higher content of aluminum, so it has better corrosion resistance, especially in the humid environment performance is better. While 3003 aluminum plate contains manganese, although manganese can improve the strength and hardness of the aluminum plate, but it will also affect the corrosion resistance of the aluminum plate.
Fourth, the application field
1100 aluminum plate and 3003 aluminum plate in the application field is also different. Because 1100 aluminum plate has good plasticity and corrosion resistance, it is widely used in construction, electrical appliances, chemical industry and other fields. While 3003 aluminum plate has higher hardness and strength, it is suitable for the fields that need higher strength and hardness, such as car body, aviation manufacturing and so on.
V. Surface quality
The surface quality of 1100 aluminum plate and 3003 aluminum plate is also different. Because the plasticity of 1100 aluminum plate is better, so the surface finish is higher, suitable for the field that requires high requirements of surface quality. While the surface quality of 3003 aluminum plate is relatively poor, but due to the high hardness and strength, it is also used in some less demanding fields.
Sixth, the price
The price of 1100 aluminum plate and 3003 aluminum plate is also different. Due to the higher purity of 1100 aluminum plate, the processing cost and production cost will be increased, so the price is relatively high. While 3003 aluminum plate is more common, the price is relatively low.
