Hydro's Tolerances Booklet
A useful booklet in pocket size that covers the standards EN 755-9 and EN 12020-2 for the extrusion of aluminium.
Tolerances for dimension and form of extruded profiles
Covers the tolerances for dimension and form of extruded profiles for big profiles and alloys that are more difficult to extrude.
Covers more precise standard tolerances on dimensions and shapes, realizable with the most applied alloys, namely 6060 and 6063.
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 Hydro.
