EN AW-6082 \u00b7 AlSi1MgMn \u00b7 W.Nr. 3.2315 \u00b7 UNS A96082 \u00b7 old British designation HE30 \u00b7 Per EN 573-3: Si 0.70-1.30 % \u2013 Mg 0.60-1.20 % \u2013 Mn 0.40-1.00 % \u2013 Fe max 0.50 % \u2013 Cr max 0.25 % \u2013 Zn max 0.20 % \u2013 Cu max 0.10 % \u2013 Ti max 0.10 % \u2013 balance Al. This is a 6xxx series Al-Mg-Si-Mn alloy and it IS HEAT-TREATABLE: solution treatment 525-540 \u00b0C + quench + ARTIFICIAL ageing 155-190 \u00b0C. Hardening comes from Mg2Si (beta”) precipitation. The tempers are T4, T6, T651 and, in extrusions, also T5.<\/div>\n

\n
For what<\/div>\n
Bought for highly stressed structural parts that have to be weldable: bridges and lattice girders, cranes, handling equipment, scaffolding, rail vehicle components, marine and offshore structures, machine frames and machined parts, vessel shells.<\/div>\n<\/div>\n

NO VERIFIED AMS NUMBER WAS FOUND for this alloy; 6082 does not appear in the aerospace specification systems. In aerospace the equivalent of this band is 6061 and the AMS numbers belong to 6061 (for example AMS 4116 = 6061-T4).<\/span><\/div>\n<\/div>\n
\n
Advantage<\/div>\n
The highest specification strength among the weldable aluminium alloys: EN 755-2 requires Rp0.2 min 260 MPa and Rm min 310 MPa for T6 extruded rod of 20-150 mm. In the same standard the limit for 6060 T6 is 150 MPa \/ 190 MPa, and in EN 485-2 the limit for 5754 H22 is 130 MPa \/ 220-270 MPa.<\/div>\n<\/div>\n
\n
Welding<\/div>\n
Weldable. MIG is rated 1 (very good) on producer scales, TIG 2 (good), resistance welding 3 (moderate). Filler metal: 4043 \/ AlSi5 for self-welding, and 5356 \/ AlMg5 when joining to an alloy such as 7005 or when higher weld metal strength is wanted; BIKAR also lists SG-AlMg4 and SG-AlMg4.5Mn.<\/div>\n<\/div>\n
\n
Limits<\/div>\n
The first limit is THE WELD ZONE: the HAZ overages and softens and the proof strength falls by roughly half. Designing a welded structure to the 6082 T6 table is a mistake. The second limit is QUENCH SENSITIVITY: the alloy is quench sensitive;<\/div>\n<\/div>\n
