Aluminum Rolled Plates

the standard among aluminum plates

Aluminum rolled plates – well-established standard materials, however the use of them needs to be carefully considered.

If the benefits of the material aluminum should be used, usually for the most applications the well known conventional aluminum rolled plates are chosen. This might be a very time- and also cost-expensive decision.

Aluminum rolled plates have a couple of difficult properties such as residual stress, a poor parallelism and flatness, and in general directional properties inside the plate. This poor characteristics of aluminum rolled plates can cause production errors or a distortion which also leads to waste.

The use of aluminum rolled material also requires enormous efforts during the machining. If the component needs to have very narrow tolerances in thickness and flatness it is necessary to do the cnc-machining of aluminum rolled plates with caution by multiple turning around the work piece and with enough resting phases. This makes the machining very time- and cost-expensive. Due to the high residual stress-level of aluminum rolled plates it often happens that the finished components does not meet the requirements which again causes an expensive rework. The loss of strength (up to 40%, depends on the thickness) from the plate center to the core, which is another bad characteristic of aluminum rolled material, additionally leads to a non-uniform loads which increases the tool wear.

Due to all that reasons we highly recommend the use of G.AL® Aluminum Cast Plates.

However, if this is from the view of engineering & design not possible to switch to aluminum cast plates, or your customer insists of using rolled aluminum, we are also able to help you. With a wide range of high-quality rolled plates we can offer the following product types:
