Cold rolled BS-1470 6802 Aluminum alloy sheet
6082 belongs to 6 × × × series (Al-Mg-Si) alloy aluminum plate, is able to heat treatment can strengthen the aluminum alloy sheet, with medium strength and good welding performance, corrosion resistance, mainly for transportation and structural engineering industry. Such as bridges, cranes, roof structures, transport aircraft, transport ships and so on. In recent years, with the rapid development of shipbuilding industry at home and abroad, to reduce the hull weight, improve the speed, to seek alternative to steel parts of aluminum alloy materials, aluminum processing industry and shipbuilding industry has become an important issue. 6082 aluminum alloy aluminum plate with moderate strength and good corrosion resistance, light weight, is the manufacture of high-speed ship components ideal material.

Smelting process:
1, smelting
6082 alloy is characterized by Mn, Mn is a refractory metal, melting temperature should be controlled at 740-760 ºC. Mix evenly before mixing more than twice to ensure that the metal completely melted, the temperature is accurate, the composition of uniform. After mixing in the middle of the depth of the aluminum liquid, the furnace on both sides of the left and right to take a sample for analysis, sub-qualified after the converter.
2, purification and casting
Melt into the furnace after the furnace, with nitrogen and refining agent for powder, jet refining, refining temperature 735-745 ºC, time 15 minutes, after the end of refining for 30 minutes. Through this process degassing, deslagging, purifying the melt.
There are two filter devices between the mold and the furnace. There are foam ceramic filter plate (30PPI) in the furnace, and then filtered with 14 mesh glass fiber cloth before casting. The oxide and slag in the melt are filtered.
6082 alloy aluminum casting temperature is high (compared to 6063 aluminum normal process), casting speed is low, water flow is too large, the above process to be strictly controlled, can not be out of range, or easily lead to casting failure.
