T63 – 21 ksi. Use of an oil base lubricant during machining operations is recommended. T61 F for 6 hours and air cool.

T6 – 22 ksi. B17 specification covers aluminum-alloy extruded bar, rod, tube, pipe, Schedules 40 and 80structural profiles, and profiles in selected tempers for use as electric conductors.

Pipe or tube may be produced through porthole or bridge type dies. Aging is done at different temperatures and times, depending upon satm finished temper desired as follows: Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively.

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.


Either carbide or high speed tool steel tooling may be used.

It is hardened strengthened by heat treatment. Electrical resistivity and conductivity shall be determined.

Combining values from the two systems may result in non-conformance with the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Easily cold worked, or cold formed in either the annealed or aged conditions. Modulus of Elasticity Tension. 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. The preferred method of welding is by means of inert gas arc welding for best results. Shear strength values are: Hardens due to cold working or aging heat treatment — see “Aging”. T63 F for 19 satm and air cool. See also Cold Working.

Filler rod of the same alloy should be used. Welding by all of the standard processes may be done, including gas torch welding.


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 bars, rods, tubes, b37, structural profiles and profiles shall be produced by hot extrusion or by similar methods. T6 F for 20 hours and air cool. This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties.

This abstract is a brief summary of the referenced standard. The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. Forming characteristics are good by conventional processes. The values stated ashm each system may not be exact equivalents; therefore each system shall be used independently of the other.

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. No data, although the alloy is considered forgeable. Hot working generally is atsm required because the alloy has very good cold working characteristics.
