The presence of niobium carbide (NbC) in cemented carbides enhances the performance of cutting tools and hot-pressing dies by increasing their overall hardness and improving their resistance to both shock and erosion.1

By incorporating niobium into these materials, manufacturers can achieve superior durability, which is essential for tools subjected to the high-stress environments typical of industrial cutting and pressing applications.1
