Notes:
• The table contains processed, condensed data from EN 485-2.
• Ahol A50 value is not given, the standard specifies the “A” (elongation) value.
• Bend radius values are indicative (rmin ≈ k·t).
• HBW: Brinell hardness with carbide ball.
The values and data below are indicative – they help to give a general picture of the material.
