RG type (Corrosion Resistant Tungsten Carbide) Alloys featuring in that binder phase reinforcement is added so that the Co phase,which may cause corrosion,is solid-solution reinforced,thus improved in heat resistance corrosion resistance.Particularly,electrolytic corrosion due to wire cut and corrosion after polishing are prevented. Reinforced binder phase reduces occurrence of chipping and thermal cracks. Material grade Density g/cm3 Hardness HRA T.R.S. MPa Comp.S.
