Historical Version s – view previous versions of standard. T63 – 21 ksi. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Combining values from the two systems may result in non-conformance with the standard. T6 F for 20 hours and air cool. Welding by all of the standard processes may be done, including gas torch welding.
T61 – 17 ksi.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Modulus of Elasticity Tension. Electrical resistivity and conductivity shall be determined.
It is hardened strengthened by heat treatment. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending aztm, respectively. Easily cold worked, or cold formed in either the annealed or aged conditions. Annealing is done at F for 3 hours at temperature, followed by controlled cooling at a rate of 50 F per hour down to F, then air cool.

Machinability by conventional means is good. This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
No data, although the alloy is considered forgeable.
The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. This specification covers aluminum-alloy extruded bar, rod, tube, pipe, Schedules 40 and 80structural profiles, and profiles in selected tempers for use as electric conductors. Link to Active This link will always route to the current Active version of the axtm.
Filler rod of the same alloy should be used. Electrical bus bar conductor applications for use in enclosed bus electrical installations. This abstract is a brief summary of the referenced standard.
Forming characteristics are good by conventional processes. Pipe or tube may be produced through porthole or bridge type dies. Use of an oil base lubricant during machining operations is recommended. T61 F for 6 hours and air cool.
A stress relief anneal after cold working may be done at F with air cooling. T6 – 22 ksi.

The preferred method of welding is by means of inert gas arc welding for best results. When welded in the heat treated condition the subsequent parts will be lower in strength because of weld heat input. See also Cold Working. Hot working generally is not required because the alloy has asfm good cold working characteristics. Shear strength values are: Type A asym, last covered in the issue of this specification, is no longer available; therefore, requirements for cold-finished rectangular bar have been deleted.
Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 7 distributors but is also available to a lesser extent in Tubular Products.
The AL alloy does respond to heat treatment which is accomplished by v317 and relatively low temperature aging. Either carbide or high speed tool steel tooling may be used. T63 F for 19 hours and air cool. The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. See “Annealing” and “Aging”.
Aging is done at different temperatures and times, depending upon the finished temper desired as follows:
