G.AL® C330R Aluminium Cast Plate – Precision Sawed for High‑Strength Applications
The higher-strength aluminum plate G.AL® C330R from alloy EN AW 7021 (AlZn5.5Mg1.5) with material temper T79 sawn on all sides is characterized by very high strength and hardness as well as very good low-stress properties. The very low strength and hardness decrease from plate edge to the centre makes G.AL® C330R a superior material in virtually all sectors of the capital goods industry.
