Very hard materials with high ductility are very useful as high pressure anvils or cutting tools. Natural polycrystalline diamond, carbonado, has been used as a special drawing die. However, the amount of this product is limited. It is difficult to produce polycrystalline diamond without binder materials. Silicon or cobalt with other elements have a practical use as a binder.
