PDC is suitable for
producing drill bits of petroleum, coalfield and geology,
trimming tools and cutting tools and so on. PCBN has good
toughness, high wear-ability, and chemical stability to
the metals of iron group. It has became a kind of new
cutting tools' material to processing hard black metal
such as cooling hardness nickel chromium cast-iron, high-chromium
iron and case-hardened steel.
