  "summary": "Aluminium alloy 6082 (EN AW-6082, AlSi1MgMn) is a wrought Al-Mg-Si alloy with manganese. In the T6 and T651 temper the plate datasheets give a minimum 0.2 % proof stress of 255 MPa and a tensile strength of 300 MPa for plate of 6 to 12.5 mm, with 9 % elongation on a 50 mm gauge. Its density is 2.70 g/cm3 and its thermal conductivity 180 W/(m·K) in one datasheet. Suppliers call it the highest-strength 6000-series alloy and a structural alloy that has replaced 6061 in many uses.\n",
