6082 Aluminum Alloy 6082-T6 T651 AlMgSi1 (AlSi1MgMn – 3.2315) Properties
6082 Aluminum Alloy – Al 6082-T6 T651 T4 – AlSi1MgMn (AlMgSi1 – 3.2315)
6082 aluminum is an Al-Mg-Si heat-treatable reinforced alloy with good formability, weldability, machinability, medium strength, and good operability after annealing. The main tempering conditions include 6082-T6, T4, T651, etc. Alloy 6082 is registered in 1972 by European Aluminium Association (EAA), it is a very common alloy product in Europe because it has higher strength (tensile strength is 10% to 18% higher than Aluminum 6061, depending on thickness) and better overall corrosion resistance (due to lower copper content) than Al-6061, and approximately equal density 0.098 lb/in3 (2,710 kg/m3), extrudability and anodizing response.
Although 6082 material is also a registered Aluminum Association alloy, it has not been included in some ASTM aluminum material specifications to date because the necessary statistics to establish minimum mechanical properties in the United States have not been collected and provided. 6082 aluminum alloy is gaining more attention in the United States, but it is far less used than 6061 and 7075.
AA 6082 is equivalent to AlMgSi1 (3.2315) in German standard DIN 1725-1 and AlSi1MgMn in European standard EN 573-3.
