Advantage

Compared to ceramic substrate, metal substrate has more advantages:
1. Better heat conduction, fast heating.
2. Lower back pressure.
3. Larger effective area.
4. Greater catalytic capacity.
5. Smaller and more flexible design.
6. Thinner wall.
7. Higher mechanical strength.
8. Better resistance to thermal shock and resistance to thermal fatigue.
9. Longer service life.

Working principle

When high-temperature car exhaust passes through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, hydrocarbons, and NOx gases, promoting them to undergo certain oxidation-reduction chemical reactions. CO is oxidized to colorless and non-toxic carbon dioxide gas at high temperatures; Hydrocarbons oxidize into water (H2O) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. Three types of harmful gases are transformed into harmless gases, which purify car exhaust gas

Application

1. Round & Oval 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.
