![]() Overall, there are several different materials that can be used in catalytic converter construction depending on the desired performance characteristics and budget constraints associated with each project. However, this type of substrate is also much more expensive than either ceramics or metals due to the high cost associated with coating it with precious metals like platinum or palladium. This type of substrate offers superior performance compared to other materials due to its high surface area-to-volume ratio and ability to withstand higher temperatures without degrading over time. Finally, some catalytic converters use precious metal-coated foam as their substrate material instead of either ceramics or metals.Metal substrates also tend to be more cost-effective than ceramic ones due to their lower production costs and longer lifespan. These substrates are typically made from stainless steel or titanium and provide greater durability than ceramic substrates while still providing adequate surface area for reaction with exhaust gases. In addition to ceramic substrates, metal substrates are also used in some catalytic converters.The honeycomb structure provides a large surface area for the catalyst to react with exhaust gases, allowing for a more efficient conversion of pollutants into less harmful substances. This substrate is made from a combination of alumina and other metals such as palladium, platinum, and rhodium. The most common material used in catalytic converters is a ceramic honeycomb substrate.As such, it is important to understand the different materials used to make catalytic converters.
