Metal Substrate Vs Ceramic Catalytic Converter

Metal foil substrates are being promoted as the substrates of choice for automotive catalytic converters in the european market.

Metal substrate vs ceramic catalytic converter.

A catalytic converter is basically a long screen made of either ceramic or a metal foil. 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. Thinner walls are seen to offer both lower flow restrictions and improved catalytic performance while metal s thermal characteristics are seen to benefit both performance and durability. This screen is dipped and coated in a bath of liquid metal.

Metallic vs ceramic catalytic converters ceramics have primarily been used as the substrate for catalytic converters and share a bigger market than metallic substrates. The metallic ones are usually used on obd1 applications.

Typically the ceramic converters are used on obdii vehicles. Engineers prefer metallic whereas coating companies prefer ceramic. Visit this section get information about the benefits of metal substrate over ceramic substrate. The recipe for this bath is made up of precious metals like platinum gold and rhodium.
