Specifies requirements for aluminium and aluminium alloy extruded rod, bar, solid and hollow shape products for general engineering purposes. Chemical composition and mechanical properties are specified, and allowable tolerances on dimensions are included for rod, bar, solid shapes, and Class A, Class B, Class C and Class D hollow shapes. Examples illustrating the use of tolerance are included.

This Standard specifies requirements for aluminium and aluminium alloy extruded rod, bar, solid and hollow products for general engineering purposes.NOTES:Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.Typical fabrication characteristics and application data for wrought aluminium and aluminium alloys are given in Appendix B.
