Tolerances Booklet

The Tolerances booklet is a useful book in pocket size. It covers standards EN 755-9 and EN12020-2 for the extrusion of aluminium.

EN 755-9

Covers the tolerances on dimensions and shapes for all extruded aluminium profiles in all applied alloys.

EN 12020-2

Covers more precise standard tolerances on dimensions and shapes, realizable with the most applied alloys, namely 6060 and 6063

Closer tolerances

Closer tolerances than the prescribed standard tolerances are possible for both EN 755-9 and EN 12020-2. But they have to be fixed in close collaboration with Sapa.

Do you want to know more about the possible tolerances for your specific design? Or would you like to receive a copy of the Sapa tolerances booklet? Don't hesitate to contact us, we would be very pleased to help you.
