EN AW-6060 / ISO: Al MgSi Applications
Evenals de legering AlMgSi 1 is de kwaliteit  AlMgSi 0,5  een precipitatie hardbare legering. Door de gunstige combinatie van goede warmvervormbaarheid (bijvoorbeeld extruderen) en redelijke sterkte in uitgeharde toestand wordt deze kwaliteit veelvuldig gebruikt voor de fabricage van uiteenlopende profielen. Toepassing van gecompliceerde profielen kan in de produktie een aantal bewerkingen (zetten, lassen) uitsparen en daardoor de productieviteit verbeteren.
Onder "normale" atmosferische omstandigheden en ook in wat agressievere omgevingen zoals maritieme milieus heeft de kwaliteit AlMgSi 0,5 een uitstekende weerstand tegen corrosie, die nog verbeterd kan worden door anodiseren.
Bij het lassen dient rekening gehouden te worden met een daling van de sterkte in de warmtebeïnvloede zone en de gevoeligheid voor warmscheuren. Door een geschikte warmtebehandeling (oplosgloeien en uitharden) is de sterkte van de wamtebeïnvloede zone weer op het oorspronkelijke niveau te brengen. De lasnaad daarentegen zal in principe altijd een lagere sterkte hebben dan het basismateriaal. Door de warmscheurgevoeligheid zal in het algemeen met een geschikt toevoegmateriaal gelast moeten worden. Toepassingen zijn o.a. te vinden in de apparatenbouw (opslagtanks, drukvaten), de bouw (dragende constructies, roldeuren), transportmiddelen en de jachtenbouw (masten).
Lasbaarheid: enigzins gevoelig voor warmscheuren; daling sterkte
Lastoevoegmateriaal: 5356, 4034
Warmtebehandelingen: warmvervormen 520 -450șC / zachtgloeien 360 -400șC, tot 250șC langzaam afkoelen / oplosgloeien 525 -540șC, afschrikken in water / uitharden 155-190șC, 4 gedurende 4 tot 16 uur

Full tempers: O
O Annealed - products achieving the required annealed properties after hot forming processes may be designated as O temper.
O1 Thermally treated at approximately the same time and temperature required for solution treatment and slow cooled to room temperature.
O2 Thermomechanically processed to enhance formability, such as required for super-plastic forming (SFP).
O3 Homogenized.
 
Full tempers: T1
T1 Cooled from elevated temperature shaping process and naturally aged.
T1X Cooled from elevated temperature shaping process and naturally aged. When a second digit is present it is material dependent and has no general interpretation.
 
Full tempers: T4
T4 Solution heat treated and naturally aged.
T42 Solution heat treated from the O or the F temper to demonstrate response to heat treatment, and naturally aged to a substantially stable condition.
T4X Solution heat-treated and naturally aged. When a second digit is present it is material dependent and has no general interpretation except for T42.

T62 Solution heat treated from the O or the F temper to demonstrate response to heat treatment, and artificially aged.
T651 Solution heat treated, stress relieved by stretching a controlled amount (permanent set 1.5 to 3% for sheet and plate, 1 to 3% for rolled or cold finished rod and bar, 1 to 5% for hand or ring forging and rolled ring) and then artificially aged. The products receive no further straightening after stretching.
T6510 Solution heat treated, stress relieved by stretching a controlled amount (permanent set 1 to 3% for extruded rod, bar, shapes and tube, 0.5 to 3% for drawn tube) and then artifically aged. The products receive no further straightening after stretching.
T6511 Same as T6510 except that minor straightening is allowed after stretching to comply with standard tolerances.
T652 Solution heat treated, stress relieved by compressing to produce a permanent set of 1 to 5% and then artificially aged.
T654 Solution heat treated, stress relieved by restriking cold in the finish die and then artificially aged.
T66 Solution heat treated and then artificially aged - mechanical property level higher than T6 achieved through special control of the process (6000 series alloys).
