Aluminium alloy 2011 is a high mechanical strength alloy that machines exceptionally well. Often called a Free Machining Alloy or ‘FMA’ it is well suited to use in automatic lathes.
ALLOY DESIGNATIONS
Aluminium alloy EN AW 2011 is covered by Standard BS EN 2100 and has similarities to the following standard designations and specifications:
Alloy 2011 UNS A92011, ASTM B209
DIN AlCu6BiPb, 3.1655
TEMPER TYPES
The most common tempers for 2011 aluminium are:
- O - Soft
- T3 - Solution heat treated, cold worked and naturally aged
- T4 - Solution heat treated and naturaly aged to a substantially stable condition.
- T8 - Solution heat-treated, cold worked and then artificially aged.
- T451 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged (between T73 and T76). The products receive no further straightening after stretching.
SUPPLIED FORMS
2011 aluminium is supplied in round bar.
