Principal Design Features		This is generally considered to be an extrusion alloy that is heat treatable for strengthening.

Applications		Commonly used in the manufacture of furniture, windows, stair rails, and in pipe railing. Commonly used in architectural extrusions.

Machinability		Machinability is considered to be average for this alloy.

Forming		Forming ability, either hot or cold, is good.

Welding		The alloy is readily welded by all of the conventional methods. Filler rod should be of the same alloy or AL 4043 alloy.

Heat Treatment		Solution heat treat at 970 F for 1 hour followed by water quench. This produces T 4 temper. Other tempers are accomplished by aging.

Forging		Hot forging may be done in the range of 500 F to 950 F.

Hot Working		Hot working, as with forging, may be done at temperatures above 500 F up to maximum of 950 F.

Cold Working		Cold working characteristics are good for all conventional forming methods.

Annealing		Anneal at 775 F for 3 hours and use controlled cooling at rate of 50 F per hour down to 500 F. Then air cool.

Aging		Aging is done at a temperature of 350 F for 8 hours for T 6 and T 62 tempers. Age at 360 F for 3 hours to get T5 temper.

Tempering		Not applicable.

Hardening		Hardens due to aging heat treatment and cold working. See "Aging".

Other Physical Props		Electrical conductivity 50% of copper.

Other Mechanical Props		Shear strength for various tempers is: O temper 10, ksi . T 5 temper 17 ksi. T 83 temper 22 ksi
