Catalyst Metallic

the heat-resisting impact performance to be good, with catalyst coating binding force, the braze welding intensity is reliable.

Catalyst Metallic  

Wisdom Technologies is a founder and leader in R&D, manufacturing of metallic substrate in China, which has provided hundreds of varieties of metallic substrates to customers worldwide.

Application

1.      Round & Ovel metallic substrate for On-road vehicle;

2.      Metallic substrate for small engine;

3.      Metallic substrate for Off-road vehicle;

4.      Metallic substrate for industrial catalyst;

5.      Specific structure metallic substrate for other application.

 

Why metallic?

Metal-based monolith substrate offers many advantages in comparison with a ceramic one, for instance:     

    Shorter light off time;

    Less risk of overheating;

    Less back pressure;

    Larger effective area;

    Greater catalytic capacity;

    Smaller and more flexible design;

    Thinner walls;

    Higher mechanical strength;

    Better resistance to thermal shock.
