Shear strength values are: Aging is done at different temperatures and times, depending upon the finished temper desired as follows: 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. Forming characteristics are good by conventional processes. The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods.

Electrical bus bar conductor applications for b17 in enclosed bus electrical installations. 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.

T63 F for 19 hours and air cool. The preferred method of welding is by means of inert gas arc welding for best results. T6 – 22 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 Aetm, then air cool.


Welding by all of the standard processes may be done, including gas torch welding. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. When welded in the heat treated condition the subsequent parts will be lower in strength because of zstm heat input.

Machinability by conventional means is good.

Either carbide or high speed tool steel tooling may be used. Use of an oil base lubricant during machining operations is recommended. Electrical resistivity and asfm shall be determined.

This abstract is a brief summary of the referenced standard. Pipe or tube may be produced through porthole or bridge type dies. T63 – 21 ksi. It is informational only and not an official asrm of the standard; the full text of the standard itself must be referred to for its use and application. Hardens due to cold working or aging heat treatment — see “Aging”. Historical Version s – view previous versions of standard.

See “Annealing” and “Aging”. Hot working generally is not required because the alloy has very good cold working characteristics. T61 F for 6 hours and air cool.

Modulus of Elasticity Tension. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively. It is hardened b37 by heat treatment.


T61 – 17 ksi. T6 Astmm 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.

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.

Combining values from the two systems may result in non-conformance with the standard. Link to Active This link will always route to the current Active version of the standard.

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 AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. Easily cold worked, or cold formed in either the annealed or aged conditions.
