European foreword
This document (prEN 755-2:2023) has been prepared by Technical Committee CEN/TC 132 “Aluminium
and aluminium alloys”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 755-2:2016.
Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 5
“Extruded and drawn products” to revise EN 755-2:2016.
The main changes compared to the previous edition are listed below:
— addition of the alloy EN AW-2033 in Table 11;
— addition of the alloy EN AW-2077 in Table 12;
— addition of the alloy EN AW-6050 in Table 39;
— modification of the order of alloys to conform with Aluminium Association System:
— addition of the terms required by the latest CCMC template;
— addition of Clause 3 compulsory from the latest CCMC template;
— deletion of former Clause 3.3 as part of the table of contents in this document;
— correction to temper of EN AW-2024 alloy in Table 10.
The EN 755 series comprises the following parts under the general title “Aluminium and aluminium
alloys — Extruded rod/bar, tube and profiles”:
— Part 1: Technical conditions for inspection and delivery
— Part 2: Mechanical properties
— Part 3: Round bars, tolerances on dimensions and form
— Part 4: Square bars, tolerances on dimensions and form
— Part 5: Rectangular bars, tolerances on dimensions and form

1 Scope
This document specifies the mechanical property limits resulting from tensile testing applicable to
aluminium and aluminium alloy extruded rod/bar, tube and profile.
Technical conditions for inspection and delivery, including product and testing requirements, are
specified in EN 755-1. Temper designations are defined in EN 515. The chemical composition limits for
these materials are given in EN 573-3.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
No terms and definitions are listed in this document.
4 Mechanical property limits
4.1 General
The mechanical properties shall be in conformity with those specified in Table 1 to Table 64 or those
agreed upon between supplier and purchaser and stated in the order document.
Table 1 to Table 64 contain limits of mechanical property values obtained by tensile testing according to
EN ISO 6892-1 after sampling and test piece preparation according to EN 755-1.
NOTE The mechanical properties refer to test pieces taken in the longitudinal direction. Mechanical properties
of test pieces taken in other directions can differ from those for the longitudinal direction quoted in this document.
Brinell hardness values given in Table 1 to Table 64 expressed as HBW values are for information only.
4.2 Elongation
If not otherwise agreed, the A value shall be used.
The A value for elongation is the % elongation measured over a gauge length of 5,65 S (where S is the
o
o
initial cross-sectional area of the test-piece), and expressed in percent.
For certain products the supplier may choose (if not otherwise specified in the order documents) to use
the elongation based on A Consequently, values for the A are included in the following tables.
50mm. 50mm
The A value is the elongation measured over a gauge length of 50 mm and expressed in percent.
50mm
Test pieces and their location in the specimen are given in EN 755-1.
