Ceramic or metallic catalytic converter.

This grid is coated with a metal usually platinum or palladium that acts as the catalyst with the exhaust. The metallic ones are usually used on obd1 applications. Vaneman ac rochester division general motors corporation abstract metal foil substrates are being promoted as the substrates of choice for automotive catalytic converters in the european market. Metallic catalytic converters are made using corrugated fecral foils which are rolled into a spiraling cylinder shape then put in a furnace to form an alumina al2o3 layer.

Typically the ceramic converters are used on obdii vehicles. Catalytic converters have a ceramic grid inside that the exhaust gases flow through. Ceramics have primarily been used as the substrate for catalytic converters and share a bigger market than metallic substrates. This screen is dipped and coated in a bath of liquid metal.

Metallic vs ceramic catalytic converters. The recipe for this bath is made up of precious metals like platinum gold and rhodium. The ceramic catalytic converters such as part mf99659hm are not as strong and usually do not last as long as metallic substrate converters. I attached an faq on catalytic converters for you to check out also.

In small sizes under 6 od the ceramic is usually more cost effective per piece over the metallic but due to difficulty in packaging ceramic and extra processes required the metallic total system cost often is more advantageous. Comparison between ceramic and metallic substrates with the same configuration 400 cpsi brain catalytic converters we are the first company in italy to develop an end to end production of catalytic converters.
