I-WC-Co hard alloy roller rings, enobukhulu be-HRA92, isetshenziswa ekwenzeni isikhumba se-steel esiqinile esiqondile. Ngesikhathi sokugaya izikhumba ezincane kakhulu ezingu-0.002mm, ubumpumputhe be-surface Ra bungu-≤0.08μm. I-tungsten carbide nezinye izinto ezinzima ze-alloy zine-hardness ephezulu kakhulu (80-90HSD) kanye nokumelana nokugqoka okuhle, futhi zisetshenziswa ekugayeni okuqondile kwe-wire rods encane kanye ne-steel esiqinile esiqondile esincane kakhulu (njengensimbi eyandisiwe engaphansi kwe-0.01mm).
