Metal Catalyst Substrate
A Thin-Wall Catalyst Carrier for Demanding Exhaust Environments
Alternating flat and corrugated FeCrAl foils are wound into a honeycomb core and secured inside a metal shell. The structure provides catalyst coating area while allowing exhaust gas to pass through controlled channels.
Low Flow Restriction
Thin metallic walls help maintain an open frontal area within compact converter dimensions.
Rapid Thermal Response
High thermal conductivity supports faster heat transfer in suitable close-coupled designs.
Vibration Resistance
The ductile metallic structure is suitable for motorcycles, off-road equipment and other vibration-intensive applications.
Project-Based Customization
Diameter, length, CPSI, core layout and coating scope are reviewed against the converter drawing.
Supply Configurations
Choose the Scope That Matches Your Project
We can support the metal substrate alone or continue through coating and converter assembly.
Single-Core Substrate
Compact round core for applications with limited installation space and defined flow requirements.
Bare or Coated
Multi-Core Configuration
Two-core or three-core layouts for projects requiring additional catalyst volume within a controlled package.
2-Core / 3-Core
Coated Metal Substrate
Substrate preparation and catalyst washcoat can be included for suitable TWC, DOC or SCR projects.
Coating Available
Complete Converter Assembly
Integrated support when the substrate, coating, shell and converter structure need to be developed together.
Complete Project
Supply Configurations
Designed for Compact, High-Vibration and Fast-Response Systems
Final selection should always be based on real exhaust flow, temperature, packaging and durability targets.
Motorcycle Exhaust
Compact packaging, rapid heat-up and resistance to road and engine vibration.
Close-Coupled Automotive
Suitable where the converter is positioned close to the engine and thermal response is critical.
Off-Road Equipment
Metallic construction supports applications exposed to frequent vibration and mechanical shock.
Generator & Industrial
Custom substrate and coating projects based on flow, temperature and contaminant conditions.
Metal Substrate vs. Ceramic Substrate
Neither material is universally better. The correct choice depends on installation position, durability targets, coating system, shape and cost.
| Selection Factor | Metal Substrate | Ceramic Substrate |
|---|---|---|
| Wall Structure |
Metal Advantage
Very thin foil walls and high open frontal area. |
Extruded ceramic channel walls with proven automotive use. |
| Thermal Response |
Metal Advantage
Higher thermal conductivity and rapid heat transfer. |
Lower thermal conductivity and slower heat distribution. |
| Vibration & Impact |
Metal Advantage
Ductile structure is well suited to demanding vibration conditions. |
Brittle material requires appropriate mounting and protection. |
| Thermal Expansion | Higher expansion must be considered in converter design. | Low thermal expansion is a major cordierite advantage. |
| Washcoat Adhesion | Requires suitable surface preparation and coating control. | Porous ceramic surface naturally supports washcoat anchoring. |
| Shape Flexibility | Round wound cores are the most common format. | Extrusion can support a wider range of standard non-round shapes. |
| Typical Selection Driver | Compact package, low restriction, rapid thermal response and high vibration. | Cost, low expansion, established validation and shape flexibility. |

Frequently Asked Questions
Questions Buyers Ask Before Sampling
How should I choose the right CPSI?
CPSI should be selected together with substrate diameter, length, target conversion, exhaust flow and acceptable pressure drop. A higher CPSI is not automatically better, so operating data and drawings should be reviewed together.
Can you supply only the uncoated metal core?
Yes. The project can be quoted as a bare metallic substrate, a coated substrate or a complete converter assembly, depending on your validation plan and purchasing scope.
Can you manufacture oval or runway-shaped metal substrates?
Round wound cores are the standard format. Non-round designs require a separate review of dimensions, forming method, tooling and expected order volume before feasibility can be confirmed.
What information is required for a quotation?
Please provide diameter, length, CPSI, core count, coating requirement, catalyst application, operating temperature, trial quantity, forecast volume and any available drawing or existing sample information.
What is the maximum operating temperature?
Temperature capability should not be treated as one universal number. Suitability and service life depend on the exact FeCrAl grade, foil thickness, coating system, thermal cycling, exhaust chemistry and mounting position.
Can the metal substrate be coated with TWC, DOC or SCR formulations?
These catalyst project types can be supported when the substrate design, surface preparation, coating formulation and operating conditions are compatible. Final feasibility is confirmed during technical review.
