Aluminum 6063

Aging Procedure

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.

Annealing Procedure

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.

Applications

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

Cold Workability

Cold working characteristics are good for all conventional forming methods.

Forgeability

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

Formability

Forming ability, either hot or cold, is good.

Hardening Procedure

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

Heat Treatability

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

Hot Workability

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

Machinability

Machinability is considered to be average for this alloy.

Other Mechanical Properties

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

Other Physical Properties

Electrical conductivity 50% of copper.

Principle Design Features

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

Tempering Procedure

Not applicable.

Weldability

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