CERTAL® SPC, Al rolled plate



Precision rolled plate UNIDAL® made form alloy EN AW 7019 (AlZn4Mg2), finely milled on both sides and covered with protective film, is characterized by a narrow tolerance of flatness and thickness and has only relatively low residual stresses. The good anodizing and welding capability opens up a wide range of applications for this product.
