Overview
ISO 6362-2:2022 - Wrought aluminium and aluminium alloys - Extruded rods/bars, tubes and profiles - Part 2: Mechanical properties defines the mechanical property requirements for extruded aluminium products used in general engineering applications. It applies to extruded rods, bars, tubes and profiles and provides standardized values (tensile strength, 0.2 % proof stress, elongation) and rules for testing and reporting. The document complements ISO 6362-1 (inspection and delivery) and references tensile test methods such as ISO 6892-1 and ASTM B557M.
Key topics and technical requirements
- Scope and applicability: Mechanical properties for wrought aluminium and aluminium-alloy extruded products used in general engineering.
- Tensile testing: Selection of specimens and test procedures are specified to follow ISO 6892-1 or ASTM B557M for consistent measurement of tensile strength and proof stress.
- Property tables: Values for tensile strength (Rm), 0.2 % proof stress (Rp0.2) and elongation are given in Tables 1–3 for a wide range of alloys and tempers. Producers and purchasers use these tables to specify required performance.
- Tempers and alloys: Temper designations follow ISO 2107; alloy listings refer to ISO 6362-7. Annex B lists tempers used in the tables.
- Measurement details: The standard allows two elongation gauge lengths (5.65√S and 50 mm) and gives guidance on rounding results (Annex A).
- Notes on processing: The document includes conditions where mechanical properties depend on prior processing (e.g., natural vs artificial ageing, controlled cooling after extrusion).
Practical applications and users
ISO 6362-2:2022 is essential for parties involved in the specification, production and testing of extruded aluminium components:
- Manufacturers and extruders: to qualify product batches and declare mechanical properties.
- Design engineers: to select appropriate alloys and tempers for strength, ductility and formability in structural, automotive, aerospace, marine and building components.
- Procurement and quality assurance: to write purchase specifications and acceptance criteria referenced to international values.
- Testing laboratories and certification bodies: to perform tensile tests and report results according to accepted methods.
- Fabricators and assemblers: to understand forming limits and expected performance after extrusion and heat treatment.
