6061 Aluminum Sheet

6061 Aluminum sheet

Name: 6000 series Aluminum Sheet
Alloy: 6061, 6082, 6063 etc.
Temper: O, H112, T4, T6, T651 etc.
Thickness: 6-200mm
Width: Up to 1500mm
Surface treatment: mill finished, Print marks
Machinability: In the harder T 4 and T6 tempers it is good. It is notably less easy to machine in the annealed temper.
Forming: Easily cold worked and formed in the annealed condition. Stamping, bending, spinning, deep drawing are all readily accomplished using standard methods.
Welding: It has very good welding characteristics and may be welded by all of the common welding techniques.
Heat Treatment: Solution heat treat at 990 F for adequate time to allow for thorough heating and then water quench. Precipitation hardening is done at 320 F for 18 hours and air cool, followed by 350 F for 8 hours and air cooling.
Forging: It is capable of being hot forged at temperatures in the range of 900 F to 750 F.
Hot Working: Hot working may be done in the temperature range of 700 F to 500 F.
Cold Working: Cold working in the O temper condition is readily performed. The alloy is notably less easy to cold form in the T 4 and T 6 tempers.
Annealing: Annealing should be done at 775 F for 2 to 3 hours followed by controlled cooling at 50 f per hour down to 500 F, then air cool.
Aging: The aging precipitation heat treatment is done at 350 F for 8 hours followed by air cooling. This produces the T6 temper.
