ISO 6361-2:2014

Overview

ISO 6361-2:2014 - "Wrought aluminium and aluminium alloys - Sheets, strips and plates - Part 2: Mechanical properties" defines the mechanical property requirements for flat‑rolled wrought aluminium and aluminium‑alloy sheets, strips and plates used in general engineering applications. Intended to be used in conjunction with ISO 6361‑1 (technical conditions for inspection and delivery), this part lists tensile and bend performance data by alloy, temper and thickness, and sets the rules for testing results and rounding.

Key topics and technical requirements

• Scope: Applies to flat‑rolled products (sheets, strips, plates) of wrought aluminium and aluminium alloys for general engineering use. Chemical composition is covered in ISO 6361‑5.
• Tensile testing: Mechanical property tables (Tables 1–63) give values for tensile strength, 0.2% proof stress and elongation. Two gauge lengths are provided for elongation measurement (one is 50 mm); the producer selects the gauge length unless otherwise agreed.
• Bend testing: Products shall be capable of bending cold through 180° around a pin whose radius equals a specified multiple of thickness (k × t) without cracking. Minimum bend radii for alloys, tempers and thickness ranges are provided in the tables.
• Test specimen selection and test methods: Specimen selection and testing procedures reference ISO 6361‑1.
• Result handling: Test results are to be rounded following the rules in Annex A of ISO 6361‑2.
• Designations: Alloy and temper designations follow ISO 2107 conventions.

Practical applications and users

Who uses ISO 6361-2:

• Material engineers and metallurgists selecting aluminium sheet/plate for design and fabrication.
• Quality control and testing laboratories verifying tensile and bend performance.
• Suppliers and purchasers writing specifications and inspection/delivery requirements.
• Design and manufacturing teams in transport, automotive, aerospace, construction, packaging and general engineering where aluminium sheet and plate are specified.

Practical value:

• Enables consistent specification of mechanical properties by alloy, temper and thickness.
• Facilitates supplier–buyer agreements on acceptable mechanical performance and bendability.
• Helps designers assess formability and strength limits for flat‑rolled aluminium components.
