Wrought aluminium and aluminium alloys - Cold-drawn rods/bars, tubes and wires - Part 5: Tolerances on form and dimensions for drawn square and hexagonal bars and wires
This document specifies the tolerances on form and dimensions of wrought aluminium and aluminium alloy drawn square and hexagonal bars and wires with widths across flats up to and including 100 mm. For wires, this document does not apply to electrical, welding and aeronautical purposes. For drawn bars, 4.1 to 4.5 apply, and only 4.1 applies to drawn wires.

Overview
ISO 6363-5:2022 defines the tolerances on form and dimensions for cold-drawn wrought aluminium and aluminium-alloy square and hexagonal bars and wires with widths across flats up to and including 100 mm. The third edition (2022) updates and corrects the previous edition (2012). For drawn bars, sections 4.1–4.5 apply; for drawn wires, only section 4.1 (width across flats tolerances) applies. This part of the ISO 6363 series is intended for manufacturers, purchasers and inspection bodies specifying and verifying dimensional and form tolerances for drawn aluminium products. Note: the standard does not apply to wires for electrical, welding or aeronautical purposes.
Key topics and technical requirements
- Scope limit: widths across flats ≤ 100 mm; wires for certain critical applications excluded.
- Tolerances on width across flats (4.1): plus-and-minus or minus-only tolerances provided in tabulated form (Table 1); choice agreed between purchaser and supplier.
- Fixed-length tolerances (4.2): length tolerance bands for fixed-length bars by length ranges (Table 2).
- Squareness of cut ends (4.3): limited to half the fixed-length tolerance range (applies to both fixed and random lengths).
- Corner radii (4.4): maximum corner radii defined by width ranges (Table 3) - corners shall be slightly rounded but not exceed the stated maxima.
- Form tolerances (4.5) (bars only, except certain tempers):
- Measurement method: place bar on a horizontal plate under its own mass.
- Straightness: maximum 2 mm per 1 000 mm of length (total) and ≤ 0.6 mm per 300 mm section.
- Convexity/concavity: controlled within width-across-flats tolerances.
- Twist: limits per 1 000 mm and over total length (Table 4) with different limits for s ≤ 50 mm and 50 < s ≤ 100 mm.
- Squareness deviation (Z): Z = 0.005 × s (Table 5) - measured per illustrated method.
Practical applications and users
- Useful for: aluminium drawing mills, quality control and inspection labs, procurement/specification engineers, metal fabricators, and machine shops that process or buy cold-drawn square and hexagonal aluminium bars and wires.
- Typical uses: specifying dimensional acceptance criteria in purchase orders, production quality control, incoming inspection, and dimensional reporting for components made from drawn aluminium bars and wires.
- Benefits: ensures consistent dimensional quality, reduces disputes between supplier and purchaser, and provides clear measurement and acceptance criteria for straightness, twist, squareness and corner radii.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
