Aluminum GAlSi9Cu1

Excellent castability, suitable for large components or those with substantial mass
Fine and compact grain, enabling superior quality machining
Better thermal dissipation, thanks to the presence of copper
Self-tempering effect, facilitating machining without additional treatments

Heat treatments

Although it can be machined without heat treatment, the GAlSi9Cu1 alloy can be subjected to T6 treatment, which further improves its strength and dimensional stability.
