Hardens due to cold working or aging heat treatment — see “Aging”. Welding by all of the standard processes may be done, including gas torch welding.

The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. Shear strength values are: Use of an oil base lubricant during machining operations is recommended. T63 F for 19 hours and air cool.
See “Annealing” and “Aging”. Electrical resistivity and conductivity shall be determined. Pipe or tube may be produced through porthole or bridge type dies. Distributors will offer small quantity buys while mills will generally atsm sell large quantities, with delivery times anywhere from 10 to 50 weeks depending h317 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.
Electrical bus bar conductor applications for use in enclosed bus electrical installations. This is a high electrical conductivity aluminum alloy also possessing good qstm strength properties. It is hardened strengthened by heat treatment.

Aging is done at different temperatures and times, depending upon the finished temper desired as follows: The preferred method of welding is by means of inert gas arc welding for best results. Historical Version astmm – view previous versions of asmt. Combining values from the two systems may result in non-conformance with the standard. T6 – 22 ksi. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. 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.
Hot working generally is not required because the alloy has very good cold working characteristics. Modulus of Elasticity Tension. Link to Active This link will always route to the current Active version of the standard. When welded in the heat treated condition 3b17 subsequent parts will be lower in strength because of weld heat input. No data, although the alloy is considered forgeable. Filler rod of the same alloy should be used. T61 F for 6 hours and air cool. 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.
Either carbide or high speed tool steel tooling may be used. T6 F for 20 hours and air cool. Easily cold worked, or cold formed in either the annealed or aged asstm. 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.
The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. See also Cold Working.
Tensile properties of the specimens such sstm tensile and yield strengths and bending shall be determined by tension test and bending test, respectively. Forming characteristics are good by conventional processes. Type A material, last covered in the issue of this specification, is no longer available; therefore, requirements for cold-finished rectangular bar have been deleted.
This abstract is a brief summary of the referenced standard.
T63 – 21 ksi. T61 – 17 ksi.

The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. A stress relief anneal after cold working may be done axtm F with air cooling. Machinability by conventional means is good.
