CBN A10:Amber colored and irregularly shaped crystals with medium brittleness,recommended for metal bond system and vitrified system including abrasive tools and grinding wheels for better self-sharpening performance and extended life,and electroplated tools for processing ferrous metals and alloys.
CBN A10+:Yellow mono-crystal, transparent, regular shape, high toughness and hardness. Suitable for electroplated，vitrified and metal bond tools, wheels etc. The tools have long service life. 
CBN B10:Brittle,black crystals with irregular shape. CBN-B10 is characterized by its excellent self-sharpening feature. Instead of large pieces, only small chips crack from CBN crystal grain under impact, therefore, the grain remains constantly sharp. Recommended for vitrified bond tools for processing ferrous metals and alloys. 
CBN B10+:Black mono-crystal, irregular shape, low toughness. Mainly used for resin bond tools and wheels, electroplated and vitrified bond tools. The tools have good self-sharp ability
CBN A20:Brown, transparent  single crystal, crystal is complete rules with high toughness and shapeness, superior truncation tetrahedron form. Suitable for  ceramic bond grinding tools, grinding wheel, can also be used for metal bond products, suitable for processing ferrous metal materials and alloy.
CBN A20+:consists of clear amber coloured, regular shaped monocrystals with high toughness and good thermal stability. It is used primarily for metal, vitrified bond and electroplated tools and grinding wheels, which have longer service life, suitable for grinding ferrous metals and alloy.        
  
CBN B20:Bright and black colored, blocky shaped crystals with high impact strength and excellent thermal stability, suitable for metal bond electroplated bond and vitrified bond abrasive tools and grinding wheels.It’s with high impact load application and longer tool life, Suitable for processing ferrous metal materials and alloy. 
CBN B20+:Black color with crystal regular shape,high impact,suitable for electroplated,vitrified and metal bond tools.
CBN B30+:Bright black mono-crystal, regular shape, high  toughness and good thermal stability. Mainly used for metal, vitrified bond and electroplated tools, wheels. The tools have longer service life, suitable for grinding ferrous metals and alloy.     
CBN A30:Dark brown,irregular monocrystalline with sharp edge,tough,high thermal stability.Used in vitrified bond, metal bond and heavy-duty resin bond applications. 
Application:It is widely used in machining hardened steel, chilled cast iron, heat-resistant alloy such as ferrous metals.
