General Engineering and Manufacturing

Our G.AL® Cast Plates are renowned for their exceptional machinability. All of our products, be it G.AL® Sawn Plates , G.AL® Precision Plates or allow for degrees of machining of more than 90% while holding their dimensional stability.

G.AL® Precision Plates are machined on both sides and have a very fine surface finish of less than 0.4 µm, which is protected by a PVC film on both sides.

The most popular plate is G.AL® C250 (EN AW 5083), renowned for its versatility, corrosion and heat resistance and its good strength-to-weight ratio.

Depending on the complexity of a component, the machining time of a workpiece using G.AL® C250 can be reduced by more than 40% compared to high-strength rolled plates; for lower-strength rolled plate types, nearly 30% of machining time can still be saved.

With thickness tolerances of +/- 0.004” and a flatness tolerance of 0.005”, as well as very good parallelism, G.AL® Precision Plates make lengthy thickness machining and extra steps obsolete. Saving this extra step during the manufacturing process alone saves a producer time and money, as bringing an aluminum rolled plate to the required dimensional and shape accuracy often involves time-consuming processes with multiple flips and rest periods.

Warping, tool wear, and time-consuming machining steps such as milling to thickness, have been a thing of the past since the market introduction and further development of G.AL® Precision Plates

Due to the lack of forming (rolling, forging), G.AL® Cast Plates have isotropic properties, i.e., the material behaves the same in all directions. The very low strength drop from edge to center (<10%) results in extremely low stress and uniform conditions over the entire cross-section, significantly minimizing tool wear.

The inherent, enormous strength drop from the edge to the center, on the other hand, of every rolled plate, up to 40% (depending on thickness), leads to uneven tool loading and thus to increased tool wear.
