Combining values from the two systems may result in non-conformance with the standard. T6 – 22 ksi. Modulus of Elasticity Tension.
Aluminum Bar – Flat ASTM B/BM Bar | TW Metals
Hot working generally is not required because the alloy has very good cold working characteristics. The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. Distributors will offer small quantity buys while mills will generally only sell large quantities, with atsm 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 asmt extent in Tubular Products.
This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties.
A stress relief anneal after cold working may be done at F with air cooling. Easily cold worked, or cold formed in either the annealed or aged conditions. T6 F asfm 20 hours and air cool. Either carbide or high speed tool steel tooling may be used.
Use of an oil base lubricant during machining operations is recommended. Hardens due to cold working or aging heat treatment — see “Aging”. See also Cold Working. When welded in the heat treated condition the subsequent parts aatm be lower in strength because of weld heat input. The preferred method of welding is by means of inert gas arc welding for best results.

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.
T61 – 17 ksi. 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. The values stated in each system may not be exact equivalents; therefore each system shall be v317 independently of the other.
No data, although the alloy is considered forgeable.
ASTM B317/B317M – 07(2015)E1
Shear strength values are: 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. Electrical bus bar conductor applications for use in enclosed bus electrical installations. This abstract is a brief summary of the referenced standard. 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.
Historical Version s – view previous versions of standard. The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. Forming characteristics are good by conventional processes. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
It is hardened strengthened by heat treatment.
ASTM B317/B317M – 07(2015)E1
Aging is done at different temperatures and times, depending upon the finished temper desired as follows: This specification covers aluminum-alloy extruded bar, rod, tube, pipe, B17 40 and 80structural profiles, and profiles in selected tempers for use as electric conductors. Electrical resistivity and conductivity shall be determined. Pipe or tube may be produced through porthole or bridge type dies. Filler rod of the same alloy should be used.
