Abstract

To improve the heat resistant properties of sintered hard metals, in particular with a view to achieving greater cutting powers during use as the cutting tool, it is proposed to alloy aluminium-containing complex nitrides and/or aluminium-containing complex carbides, in particular from the family comprising the H, chi or kappa phases, with the binder metal to which at least one hard material phase has been added.
