Abstract (en)

[origin: US2006162415A1] The method has a first material of lesser hardness acting as a rod-shaped carrier for a second material of greater hardness, each materials formed within a respective extrusion press tool and the plastic mass flow of the greater hardness material fed to the extrusion press tool for the lesser hardness material for providing a common plastic mass flow in the form of a rod-shaped body with a core and an outer region. An Independent claim for a device for manufacture of a hard metal workpiece is also included.
