BS ISO 6361-2:2014 pdf free.Wrought aluminium and aluminium alloys – Sheets, strips and plates Part 2: Mechanical properties.
In conjunction with ISO 6361-I, this part of ISO 6361 specifies the mechanical properties of wrought
aluminium and aluminium alloy sheets, strips, and plates for general engineering applications.
It applies to flat-rolled products.
The chemical composition of these materials is given in ISO 6361-5.
The designations of aluminium and aluminium alloys and the temper designations used in this part of ISO 6361 are in accordance with ISO 2107.
NOTE In certain countries, for purposes of mechanical properties, the thickness limit can be lowered to 0,15mm by agreement between the purchaser and the supplier, in the case of sheets and strips.

6 Mechanical properties
6.1 Tensile test
Values for mechanical properties of aluminium and aluminium alloys are given in Tables 1 to 63. For elongation, two different gauge lengths are used. The choice of the gauge length for elongation measurements (A orAomm) is at the discretion of the producer, unless otherwise agreed.
NOTE A is the percentage elongation on a gauge length of 5,65 . Aso is the percentage elongation on
a gauge length of 50 mm.
Test results shall be rounded in accordance with the rules given in Annex A.
6.2 Bend test
Sheet, strip, and plate shall be capable of being bent cold through an angle of 180°, as applicable, around a pin having a radius equal to k times the thickness, t, of the sheet, strip, or plate (for example 0,5t) without cracking. The values of the minimum bend radii for different alloys, tempers, and thicknesses are given in Tables 1 to 63.
NOTE The explanations of the numbered notes In Tables ito 63 are given after Table 63.
1) For elongation, the following two systems having different gauge lengths are adopted. The elongation measurement is conducted by the A5mm system, unless specified by the purchaser. When the Aso11 system is not specified, the measurement Is conducted by the A system.
where
A is the elongation, in percent, at a gauge length of 5,65 with S0 the section area of the parallel part;
Aomm is the elongation, in percent, at a 50 mm gauge length.
2) The bend test shall be applied only when requested by the purchaser.
3) Fortempergrades H22, H24, H26, H28, and H29. the upperlimit of tensilestrength and thestipulation of proof stress do not apply.
4) The material of temper grade 0 shall be a basis for materials of temper grades T42 or T62, and when requested by the purchaser, shall guarantee the performance of those materials.
5) A material of which the residual stress is relieved by applying tension to give a permanent deformation of 1,5 % to 3,0 % subsequent to the solution treatment and is thereafter natural-age hardened. The material of temper grade T451 shall guarantee the performance for temper grades
T65 1.
6) The mechanical properties for temper grade T42 shall be applied when the material of temper grade o is subjected to the natural-age hardening process after solution treatment by the purchaser. If the material is cold or hot worked before solution treatment by the purchaser, its mechanical properties may be lower than the specified values.
7) The mechanical properties for temper grade T62 shall be applied when the material of temper grade o is subjected to the artificial-age hardening process after solution treatment by the purchaser. If the material is cold or hot worked before solution treatment by the purchaser, its mechanical properties may be lower than the specified values.
8) The material of temper grade T351 shall guarantee the performance for temper grade T851 by being subjected to the artificial-age hardening process.
9) The material of temper grade T31 shall guarantee the performance for temper grade T81 by being subjected to the artificial-age hardening process.
10) The material of temper grade T37 shall guarantee the performance for temper grade T87 by being subjected to the artificial-age hardening process.
11) The material of temper grade T361 shall guarantee the performance for temper grade T861 by being subjected to the artificial-age hardening process.
12) The T4 temper is not normally supplied by the producers of wrought products, such as circles, strips, and sheets. It is obtained by rapid cooling after heating at a relatively elevated temperature, above 500 °C. This thermal cycle is routinely achieved when enamelling the finished products made out of this alloy, such as frying pans, pressure cookers, pans. etc.
13) Material supplied to the 1-1116 or [1321 temper shall be capable of meeting the exfoliation and intergranular corrosion performance as specified in ASTM B928 or EN 13195.
14) Material supplied to that temper shall be capable of exhibiting no evidence of exfoliation corrosion when subjected to ASTM G66 accelerated exfoliation corrosion susceptibility test and intergranular corrosion susceptibility according to ASTM G67.
15) The mechanical properties for temper grade T4 are the values specified, based on reference values obtained by one month of natural ageing at room temperature (approximately 20 °C) after solution treatment.
In the case of the tensile test made before completion of one month of natural ageing, the tensile performance of temper grade T4 may be deemed as guaranteed If the test result of the test piece which has been artificially aged after solution treatment is confirmed to satisfy the tensile performance of temper grade T6.
16) Whenever a new application of this alloy is contemplated, and if this application involves special properties, such as corrosion resistance, toughness, fatigue strength, it is strongly recommended that the user consult the producer in order to make a precise and appropriate selection of the material.BS ISO 6361-2 pdf download.BS ISO 6361-2:2014 Wrought aluminium and aluminium alloys – Sheets, strips and plates Part 2: Mechanical properties
