4 Dimensional ranges
The tolerances on dimensions and form expressed in this document cover extruded products of regular
cross-section in the form of round bars having diameters up to and including 320 mm, square bars
having width across flats up to and including 220 mm, rectangular bars having widths up to and
including 600 mm in thicknesses up to and including 240 mm and hot rolled plate in widths up to and
including 3 500 mm in thicknesses from 10 mm up to and including 200 mm.
Tolerances on dimensions and form of such products in excess of these ranges shall be subject to
agreement between supplier and purchaser and stated on the order or drawing.
5 Alloys
5.1 Chemical composition
The chemical composition limits of the alloys shall be as specified in EN 573-3.
5.2 Alloy groups
For the purposes of this document, the alloys are divided into two groups which correspond to varying
difficulty when manufacturing the extruded forging stock. The division into Group I and Group II of
these alloys is specified in Table 1.
The division into Class A and Class B alloys shall be as specified in EN 573-3. Class A covers aluminium
and aluminium alloys produced in large volume as wrought forging stock for which mechanical
properties are specified in EN 603-2. Class B covers aluminium and aluminium alloys produced in
limited volume as wrought forging stock for which mechanical properties are not specified.
