1000 series and 3000 series aluminum coils are two different aluminum products. They have obvious differences in composition, performance and use. Huawei Aluminum will conduct a detailed comparison of these two aluminum coils from multiple angles.
1. Comparison of ingredients
1000 series aluminum coils belong to the pure aluminum category. They only contain aluminum elements in their composition, and the content is very high, usually above 99.00%. This high-purity aluminum coil has good electrical and thermal conductivity and excellent corrosion resistance. Due to its single ingredient, the production process is relatively simple and the price is relatively cheap.
The 3000 series aluminum coil is an alloy aluminum coil whose main component is aluminum, but a certain amount of manganese is added, usually between 1.0-1.5. In addition, other trace elements, such as magnesium and iron, may be added to 3000 series aluminum coils to improve their performance. This kind of aluminum coil has good anti-rust performance and is suitable for some occasions that require anti-corrosion.
2. Performance comparison
Physical properties: There are differences in the physical properties of 1000 series and 3000 series aluminum coils. 1000 series aluminum coils have a lower density, good softness and ductility, and are easy to process and shape. The 3000 series aluminum coils have higher density, higher hardness, higher tensile strength and yield strength, and are not easy to deform.
Chemical properties: 1000 series aluminum coils have good corrosion resistance, especially good resistance to atmosphere, water, weak acid and alkali and other media. The corrosion resistance of 3000 series aluminum coils is also good, especially in some highly corrosive environments, such as marine environments, chemical industries, etc.
Mechanical properties: The mechanical properties of 3000 series aluminum coils are better than those of 1000 series. Due to its different alloy composition and processing technology, the mechanical performance indicators such as tensile strength, yield strength and fatigue strength of the 3000 series aluminum coils are better than those of the 1000 series. This makes 3000 series aluminum coils more widely used in the manufacture of structures and components subject to greater forces.
3. Comparison of uses
1000 series aluminum coils are mainly used in applications that do not require high strength, such as construction, packaging, electronics and other fields. Due to its good electrical and thermal conductivity, it is also commonly used in heat sinks, circuit board substrates, etc. In addition, 1000 series aluminum coils are also used in some situations that require good plasticity, such as the production of foils, pipes, etc.
3000 series aluminum coils are mainly used in applications that require high strength and anti-rust properties, such as automobiles, ships, aerospace and other fields. Due to its good corrosion resistance, it is also often used in the manufacture of bridges, building structural parts and other occasions that need to withstand large loads. In addition, 3000 series aluminum coils are also used in some situations that require high hardness and wear resistance, such as the manufacture of wear-resistant parts such as pistons and cylinders.
4. Comparison of processing techniques
The processing technology of 1000 series aluminum coils is relatively simple because of its single composition, strong deformation ability, and easy processing operations such as rolling, stretching and bending. It is not easy to produce cracks and defects during processing, and the yield rate is high.
The processing technology of 3000 series aluminum coils is relatively complex because its alloy composition is complex and its deformation resistance is large. It requires multiple passes of processing to achieve the required shape and size. At the same time, the temperature and deformation amount need to be controlled during the processing to avoid problems such as cracks and deformation.
5. Price comparison
Because the 1000 series aluminum coil has a single component, the production process is simple, and the price is relatively cheap. The alloy composition of 3000 series aluminum coils is complex, the production process requirements are high, and the price is relatively high. However, considering its excellent performance and wide range of applications, the processing technology of the 3xxx series is more complex and the price is more expensive than the 1000 series aluminum coils.
