Either carbide or high speed tool steel tooling may be used. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

Aging is done at different temperatures and times, depending upon the finished aastm desired as follows: T63 F for 19 hours and air cool. This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively.

T6 – 22 ksi. 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 atm size and form required This material is stocked primarily in Bar Products by 7 distributors but is also available to a lesser atm in Tubular Products. 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.


Pipe or tube may be produced through porthole or bridge type dies. The preferred method of welding is by means of inert gas arc welding for best results. Hardens due to cold working or aging heat treatment — see “Aging”. When welded in the heat treated condition the h317 parts will be lower in strength because of weld heat input.

The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. 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. See also Cold Working. Welding by all of the standard processes may be done, including gas torch welding. Shear strength values are: The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods.

Historical Version s – view previous versions of standard.

A stress relief anneal after cold working may be done at F with air cooling. 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.

ASTM B317 Grade 6101 T6

Combining values from the two systems may result in non-conformance with the standard. T63 – 21 ksi. Filler rod of the same alloy should be used. 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. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. T61 – 17 ksi. Modulus of Elasticity Tension.

No data, although the alloy is considered forgeable. Link to Active This link will always route to the current Active version of the standard. Use of an oil base lubricant during machining operations is recommended. It is hardened strengthened by heat treatment. Electrical bus bar conductor applications for use in enclosed bus electrical installations. Electrical resistivity and conductivity shall be determined.

See “Annealing” and “Aging”. Easily cold worked, or cold formed in either the annealed or aged conditions. Forming characteristics are good by conventional processes. T6 F for 20 hours and air cool. Machinability by conventional means is good.
