1. Mechanical properties are tested in longitudinal direction, based on thicknesses between 4mm and 8mm.
    For other thicknesses please contact us.
2. Minimal radius at bending over 90° - bend line parallel to the rolling direction.

 * A value of 34 J/cm2 corresponds to 27J for a full size 10x10mm test piece
