Combining values from the two systems may result in non-conformance with the standard. This abstract is a brief summary of the referenced standard. T63 – 21 ksi. Hot working generally is not required because the alloy has very good cold working characteristics.

Asmt is done at different temperatures and times, depending upon the finished temper desired as follows: Shear strength values are: Either carbide or high speed tool steel tooling may be used. The preferred method of welding is by means of inert gas arc welding for best results. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively. Electrical bus bar conductor applications for use in enclosed bus electrical installations.

The bars, rods, tubes, pipes, structural profiles and profiles b3117 be produced by hot extrusion or by similar methods. Type Astmm material, last covered in the issue of this specification, is no longer available; therefore, requirements for cold-finished rectangular bar have been deleted.


Machinability by conventional means is good. A stress relief anneal after cold working may be done at F with air cooling.

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.

It is informational only and not an official part of the standard; the full text of the standard itself must be sstm to for its use and application. When 3b17 in the heat treated condition the subsequent parts will be lower in strength because of weld heat input.

Welding by all of the standard processes may be done, including gas torch welding. It is hardened strengthened by heat treatment.

T61 – 17 ksi. 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. Forming characteristics are good by conventional processes. Modulus of Elasticity Tension.

See “Annealing” and “Aging”. Easily cold worked, or cold formed in either the annealed or aged conditions. Electrical resistivity and conductivity shall be determined. T6 F for 20 hours and air cool. 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. The AL astmm does respond to heat treatment which is accomplished by annealing and relatively low temperature aging.

T63 F for 19 hours and air cool. No data, although the alloy is considered forgeable. T61 F for 6 hours and air cool.

ASTM B317/B317M – 07(2015)E1

Pipe or tube may be produced through porthole or bridge type dies. 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.

This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties.
