6061-T651 Wrought Aluminum Plate

6061 is a good, general purpose aluminum alloy with magnesium and silicon as its alloying elements. 6061 has the highest resistance to corrosion of all the heat treated aluminums, but strength is lower. 6061 has a wide range of mechanical properties and is readily machined and has good forming properties. 6061 welds easily, has excellent joining characteristics, and good acceptance to anodizing and other applied coatings. Electrical conductivity is 40% of copper. 6061 shapes are available from sheet and plate at Speedy Metals utilizing our high definition plasma cutter.

APPLICATIONS

6061 is commonly used for structural components, frames, brackets, jigs, fixtures, base plates, machine parts, hydraulic valve bodies, valves parts, fuse parts, gears, worm gears, rectifier parts, fasteners, truck and marine components, marine fittings and hardware, electrical fittings and connectors, hinge pins, magneto parts, appliance fittings, camera lens mounts, etc. 6061 is used for heavy duty structures requiring good strength-to-weight ratio with good corrosion resistance. 6061 is easily cold worked and formed in the annealed condition. Cutting, stamping, bending, deep drawing, drilling, tapping, etc. are all readily accomplished using standard methods

MACHINEABILITY AND WELDABILITY

6061 in the T4 condition has a machinability rating of 90% when compared to 2011 at 100%. Machines to a high finish.

6061 can be forged at temperatures in the range of 750° to 900°F. Hot working may be done in the temperature range of 500°F to 700°F

6061 can be readily welded using all the common welding techniques.

HEAT TREATING

HEAT TREATMENT
Solution heat treat at 990°F for adequate time to allow for thorough heating and then water quenched. Precipitation hardening is done at 320°F for 18 hours and air cool, followed by 350°F for 8 hours and air cooled.

ANNEALING
Annealing should be done at 775°F for at 2 to 3 hours at temperature, followed by controlled cooling at 50°F per hour down to 500°F then air cooled.
AGING
The aging precipitation heat treatment is done at 350°F for 8 hours followed by air cooling. This produces the T6 temper.
