The catalytic converter overheats because combustion takes.
Ceramic vs metallic catalytic converter.
The recipe for this bath is made up of precious metals like platinum gold and rhodium.
Manufacturing the most diverse metallic substrate product offering in the world.
A catalytic converter is basically a long screen made of either ceramic or a metal foil.
The metallic ones are usually used on obd1 applications.
The price difference in any catalytic converter is based on the loading not the base material of the honeycomb.
This grid is coated with a metal usually platinum or palladium that acts as the catalyst with the exhaust gases.
Catalytic converters have a ceramic grid inside that the exhaust gases flow through.
The herringbone corrugated acr metal units outperformed equivalent plate fin metal and conventional ceramic units and approached the performance of 25 larger ceramic converters.
Part of the science behind the best high performance cats on the market involves the use of a metal substrate or core.
Background ceramic pellets and more particularly ceramic monoliths have been the substrates of choice for automotive catalytic converters over the past fifteen years.
However metal s thermal characteristics may require the addition of insulation to compensate for rapid cooling during the ten minute shut down and hot restart portion.
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.
I contacted our representative at magnaflow about the differences in the metallic and ceramic catalytic converters.
Cats start working at 1200f and are most efficient around 2200 2300f.
The effectiveness of the converter is basically determined by the amount of precious metals present on the honeycomb substrate.
Pi is a high performance catalytic converter manufacturer specializing in the development and manufacturing of fabricated metal products and catalyst solutions for all applications.
Immediate cost effective solutions to tighter emission standards.
This screen is dipped and coated in a bath of liquid metal.
Recently however many papers 1 41 have been published promoting certain advantages of metal foil substrates over conventional ceramic monolith substrates.
Many coating companies will suggest ceramic to avoid production line change overs from ceramic to metallic.
The representative informed me that the metallic catalytic converters like part mf59956 are a bit stronger and would be good for applications where the catalytic converter is close to the header as they can handle more heat.
