Abstract
The invention relates to the application of molybdenum alloys, which are superficially hardened by means of nitriding, for female dies and comparable construction components for extruding light and nonferrous metals. It is possible through the application of these materials to achieve distinct improvements over the materials used heretofore with respect to the tool life, extrusion rate and surface quality of the extruded material.
