HOT FORGING

The semi-finished products for hot plastic deformation produced by ALMAG guarantee high performance for a wide range of use in both casting and mechanical processing.

The metallurgical characteristics of our semi-finished products allow to easily obtain the most favorable properties of the forged component in terms of durability, aesthetics and functionality. Health and environmental sustainability and respect are guaranteed by the possibility of recycling machining scraps of the production cycle virtually in their totality.
