Historical Version s – b31 previous versions of standard. The preferred method of welding is by means of inert gas arc welding for best results.

The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. The values stated in each system may not be exact equivalents; therefore asttm system shall be used independently of the other. Aging is done at different temperatures and times, depending upon the finished temper desired as follows: T6 – 22 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.

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. T61 – 17 ksi.

Aluminum Bar – Flat ASTM B/BM Bar | TW Metals

Qstm is hardened strengthened by heat treatment. Hot working generally is not required because the alloy has very good cold working characteristics. This abstract is a brief summary of the referenced standard.


Shear strength values are: Either carbide or high speed tool steel tooling may be used. See also Cold Working.

T61 F for 6 hours and air cool. 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 B371 Products by 7 distributors but is also available to a lesser extent in Tubular Products. Pipe or tube may be produced through porthole or bridge type dies.

Link to Active This link will always route to the current Active version of the standard. Easily cold worked, or cold formed in either the annealed or aged conditions. The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. Filler rod of the same alloy should be used.

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. 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. A stress relief anneal after cold asgm may be done at Aetm with air cooling. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively.


Electrical resistivity and conductivity shall be determined. Combining values from the two systems may result in non-conformance with the standard. Machinability by conventional means is good.

See “Annealing” and “Aging”. T63 F for 19 hours and air cool. T6 F for 20 hours and air cool. No data, although the alloy is considered forgeable. This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties.

Modulus of Elasticity Tension. When welded in the heat treated condition the subsequent parts will be lower in strength because of weld heat input. 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.

Hardens due to cold working or aging heat treatment — see “Aging”.

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.

Use of an oil base lubricant during machining operations is recommended. T63 – 21 ksi. Welding by all of the standard processes may be done, including gas torch welding.
