Aluminum Rectangular Bar Unpolished Mill Finish T61 Temper ASTM B 5″ | eBay
Historical Version s – view previous versions of standard. T61 – 17 ksi. See also Cold Working. It is hardened strengthened by heat treatment.
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.
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. 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.
Electrical bus bar conductor applications for use in enclosed bus electrical installations. 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.
Hardens due to cold working or aging heat treatment — see “Aging”.
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. Modulus of Elasticity Tension.
ASTM B317 Grade 6101 T6
No data, although the alloy is considered forgeable. Filler rod of the same alloy should be used.
Forming characteristics are good by conventional processes. Either carbide or high speed tool steel tooling may be used. Hot working generally is not required because the alloy has very good cold working characteristics. T63 F for 19 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. Electrical resistivity and conductivity shall be determined.
Asgm stress relief anneal after cold working may be done at F with air cooling.
Welding by all of the standard processes may be done, including gas torch welding. Shear strength values are: 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 weld heat input. Easily cold worked, or cold formed in either the annealed or aged conditions.
Aluminum T61 Extruded Round Pipe Schedule 40 ASTM B – SarahFlynnTSIt
It is informational only and not an official part of the standard; the full text of the standard itself ashm be referred to for its use and application. T61 F for 6 hours and air cool. Use of an oil base lubricant during machining operations is recommended. T63 – 21 ksi. Aging is done at different temperatures and times, depending upon the 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.
T6 – 22 ksi. 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.
ASTM B317/B317M – 07(2015)E1
The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. T6 F for 20 hours and air cool. The preferred method of welding is by means of inert gas arc welding for best results.
See “Annealing” and “Aging”. Combining values from the two systems may result in non-conformance with the standard. This abstract is a brief summary of the referenced standard. Machinability by conventional means is good. This is zstm high electrical conductivity aluminum alloy also possessing good mechanical strength properties.
