Thick plates in alloy Alumold® 600 offer the highest possible hardness and strength properties. They are mainly used for injection molds and other types of heavily loaded tools. The strength and hardness of Alumold® 600 give tools an optimum resistance to wear.
Alumold® 600 plates are made of a 7000 series alloy with high zinc, magnesium and copper contents.
