The difference between 1060 and 1070
1. Chemical composition
The chemical composition of aluminum plates 1070 and 1060 is different. The aluminum content in 1070 aluminum plate reaches 99.7%, while the aluminum content in 1060 aluminum plate is only 99.6%. In addition, 1070 aluminum plate contains 0.2% silicon, 0.25% iron, 0.04% copper and 0.03% manganese, while 1060 aluminum plate contains 0.25% iron, 0.05% copper and 0.03% manganese. Therefore, the difference in chemical composition leads to differences in the material properties of the two aluminum plates.
2. Hardness and strength
The hardness and strength of aluminum plates 1070 and 1060 also differ. Since the aluminum content in 1070 aluminum plate is higher than that of 1060 aluminum plate, 1070 aluminum plate is softer than 1060 aluminum plate. At the same time, 1060 aluminum plates are usually cold rolled during the production process to improve their hardness and strength. Therefore, 1060 aluminum plate is more suitable for applications requiring higher hardness and strength than 1070 aluminum plate.

3. Ductility and plasticity
The ductility and plasticity of aluminum plates 1070 and 1060 are also somewhat different. 1070 aluminum alloy sheet can have good ductility and plasticity after proper processing, and is suitable for occasions that require a high degree of bending and forming. The hardness of 1060 aluminum plate increases after cold rolling. Although the ductility and plasticity decrease, it still has better ductility and plasticity than other aluminum alloy materials.
4. Conductive properties
There are some differences in electrical conductivity between 1070 and 1060 aluminum plates. Because of its high purity, 1070 aluminum plate has excellent electrical conductivity and can meet high requirements for electrical conductivity. Although the 1060 aluminum plate has higher hardness and strength, it is slightly inferior in electrical conductivity.
5. Corrosion resistance
The corrosion resistance of aluminum plates 1070 and 1060 also differs. Due to its high purity, 1070 aluminum plate has good corrosion resistance and can meet some occasions that require high corrosion resistance. After cold rolling, the 1060 aluminum plate has the recommended corrosion resistance due to the protection of the aluminum oxide layer on the surface.
6. Price
The prices of aluminum plates 1070 and 1060 are also different. 1070 aluminum plate has high purity, relatively high cost, and is more expensive than 1060 aluminum plate. The 1060 aluminum plate can also be cold-rolled during the production process to improve its hardness and strength, so the price is relatively affordable.
Casting production process and its introduction
The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.
Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.
Hot rolling production process and its introduction
- 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
- 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
- 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
- 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
- 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
- 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
- 3. The production speed is generally between 1.5m/min-2.5m/min;
- 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
- 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
- 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
- 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
- 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
- 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
- 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
- 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
