Principal Design Features Probably the most commonly available, heat treatable aluminum alloy.

Applications Commonly used in the manufacture of heavy-duty structures requiring good corrosion resistance, truck and marine components, railroad cars, furniture, tank fittings, general structural and high pressure applications, wire products, and in pipelines.

Machinability Machinability in the harder T 4 and T6 tempers 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 The alloy has very good welding characteristics and may be welded by all of the common welding techniques. Gas tungsten arc welding is generally used for thin sections (less than 0.032″) and gas metal arc welding is used for heavier sections. Use alloy 4043 filler wire for best results, although a decrease in T 6 properties will result.

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 The alloy 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.

Tempering Not applicable.

Hardening See “Aging”.

Other Physical Props Electrical conductivity 40% of copper.

Other Mechanical Props Shear strength for O temper is 12 ksi and for T 6 temper it is 30, ksi
