G.AL® Cast Plates in General Engineering and Manufacturing

G.AL ® Cast Plates reduce production time and manufacturing costs in machinery, gauges, fixtures, tooling, and plant construction.


Lightweight, stable, corrosion-resistant, cost-effective, and also realized in the shortest time from conception, design, component production to final assembly of the finished system. These are the familiar demands that everyone has to deal with who operates in the wide field of machinery, tooling, or toolmaking; whether it is the designer, workshop manager, or contract manufacturer.

Our G.AL® Cast Plates are the right choice whenever dimensional stability and precision are required. Plus compared to aluminum rolled plates, G.AL® Cast Plates offer unique advantages:

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

Small drop in core strength


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.

The use of G.AL® Precision Plates can significantly influence the competitiveness and cost structure of any machining company in a very positive way. By eliminating manufacturing steps made possible by these semi-finished products, both output and delivery times can be significantly reduced. The risk of defective parts is significantly reduced by the isotropic properties, excellent flatness, and extreme stress relief.

The use of G.AL® Precision Plates thus represents an unconscious, permanent investment in the future viability of the user.
