what is 6082 aluminum sheet?
6082 aluminum sheet heat treatment can strengthen the alloy, with good formability, weldability, machinability and corrosion resistance, while a moderate strength, after annealing can still maintain good operability, mainly for mechanical structure Including bar, sheet, pipe and profile.
6082 and 6061 aluminum plate are both Al-Mg-Si aluminum alloy which can be strengthened by aging treatment, with good extrusion and forging properties, and good anodizing properties. Since 6082 is a heat treatable alloy, strength will be reduced in the weld region. 6082 aluminum sheet and plate are typically formed by rolling. Huawei offers alloy 6082 plate and sheet for highly stressed applications includes trusses, bridges, cranes, transport applications as well as mould
In addition, 6082 aluminum sheet also has the following characteristics:
1. Good formability, solderability and brazeability.
2. It has medium strength and good machinability.
3. Good usability and excellent interface characteristics.
4. Easy to process, good anode reaction performance and easy coating.
5. Good corrosion resistance and oxidation resistance.

6082 alloy aluminum sheet smelting process
1. Smelting
6082 alloy is characterized by containing Mn, Mn is a refractory metal, the melting temperature should be controlled at 740-760 ℃. Stir more than twice before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform. After stirring, take a sample in the middle of the depth of the molten aluminum and on the left and right sides of the furnace for analysis.
2. Purification and casting
After the melt is transferred to a static furnace, it is sprayed with nitrogen and a refining agent for spraying and jet refining. The refining temperature is 735-745°C for 15 minutes. After refining, it is allowed to stand for 30 minutes. Through this process degassing, slag removal, and purification of the melt.
During the casting process, there are two filtering devices between the casting mold and the furnace port. The furnace port has a foam ceramic filter plate (30PPI) for filtering. Before casting, it is filtered with 14 mesh glass fiber wire cloth to fully filter out the oxides and slag inclusions in the melt.
The casting temperature of 6082 alloy aluminum plate is high (compared to the normal process of 6063 aluminum plate), the casting speed is low, and the water flow is large. The above process needs to be strictly controlled and cannot exceed the range, otherwise it will easily lead to casting failure.
Heat treatment process of 6082 aluminum plate
Melting 6082 alloy is characterized by containing Mn, which is a refractory metal, and the melting temperature should be controlled at 740-760℃. Stir evenly for more than two times before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform. After stirring, take a sample in the middle of the molten aluminum depth and on the left and right sides of the furnace for analysis, and the converter can be converted after the analysis is qualified.
Purification and casting After the melt is transferred to the static furnace, it is sprayed with nitrogen and refining agent and refined by air jet. The refining temperature is 735-745°C for 15 minutes. After the refining, it is allowed to stand for 30 minutes. Through this process, degassing, slag removal, and melt purification. There are two filtering devices between the mold and the furnace mouth during casting. The furnace mouth is filtered by a foam ceramic filter plate (30PPI).
