  1. Very high impact toughness , very good hot hardness, good wear resistance
  2. High impact toughness , good wear resistance
  3. Very high wear resistance, good impact toughness
  4. Extremely high wear resistance , relatively high impact toughness
  5. High wear resistance, high impact toughness, transverse bend strength
  6. Exceptional wear resistance , promotes very long tool life ;  possible alternative to solid carbide  where carbide fails by fracture or where intricate tool design makes carbide difficult to fabricate ;  may be used where 10 V has proven successful to provide even greater wear resistance  and  longer tool life.
