Description

In certain applications, the use of higher-strength cast plates is not sufficient; high-strength rolled plates must be used. However, the problem with rolled plates is the wide toleration of thickness and flatness, which results in extremely complex processing. Precision rolled plate G.AL® 7075GF from alloy EN AW 7075 (AlZn5.5MgCu), finely milled on both sides and covered with protective foil, provides users with a semi-finished product which drastically reduces the time required for machining.
