Metal substrates
Core Competence: Brazed Metal Substrates
For over 40 years, Oberland Mangold has been producing metal substrates used as catalyst or filter substrates in a variety of applications, from small engines to industrial plants. Our metal substrates are characterized by high temperature stability, excellent thermal conductivity, and high mechanical strength. These properties enable close integration into exhaust systems and significantly reduce installation complexity.
Catalyic converter Structures
The cell matrix of Oberland Mangold's metal substrates consists of ultrathin, high-alloy stainless steel foils, brazed under high vacuum. This innovative structure offers:
- Large surface area for optimal catalytic conversion rates
- Minimal backpressure due to thin cell walls
- Excellent thermal and mechanical stability
- Long lifespan thanks to high resistance to thermal shocks
- Easy integration into exhaust systems through simple weldability
Applications
The applications for our metal substrates as catalyst substrates are those that demand the highest thermomechanical performance:
- Small engines
- Motorcycles
- Passenger vehicles
- Commercial vehicles
- Industrial plants
Standard Cell Structure
The standard cell structure is used as an oxidation catalyst or three-way catalyst and offers:
- Low exhaust backpressure
- A wide range of cell densities (50-1200 cpsi)
- Outstanding thermomechanical resistance
- Compatibility with almost all available catalytic coatings
WF-Structure
The WF cell structure is designed for oxidation or three-way catalysts with increased efficiency. It offers:
- Optimized channel structure for improved gas exchange
- Enhanced catalytic activity
- Improved light-off behavior
- Compatibility with various catalytic coatings
Open Filter Structure
This structure serves as a passive particle reduction system:
- Effective reduction of particle emissions (particle count & mass) for applications without active regeneration options
- Catalytically coatable
