Metallic honeycomb substrate for catalytic converter

Metallic honeycomb substrate usage:

  • Motorcycles
  • Vehicle (gasoline engine and diesel engine) exhaust system.

Two types metallic honeycomb substrate

  • Metallic substrate coated with noble metals of Pt, Pd, Rh
  • Without noble metals

Metallic honeycomb substrate for catalytic converter can meet the emission standard

  • Euro II
  • Euro III
  • Euro IV
  • Euro V
  • EPA
  • CARB

The cells of metallic substrate density:

  • 100cpsi
  • 200cpsi
  • 300cpsi
  • 400cpsi
  • 600cpsi 
  • Customized according customers demand

The shape is round, oval, racetrack and other special shape.
We can help you to make most appropriate and competitive choice according to your requirements for different vehicles and different emission standard.
