There are four sorts of car catalysts that should each be considered in different ways.
- OEM Ceramic Converters
Original equipment supplier or the converter that was put on the car from the manufacturing facility. The primary material of the converters remains cordierite ceramic that is wash-coated using priceless group steels or PGM: palladium, platinum, and rhodium. These converters comprise roughly 95 percent of all auto stimulants and have the greatest precious metal loadings.
- OEM Metallic Converters
These converters are likewise original equipment from the producer, however, have a various interior structure. The digestive tracts are made up of 409 stainless steel, wash-coated with rare-earth elements. They stand for the various other five percent of converters in the industry as well as have to be refined in different ways for reusing than ceramic cordierite systems, but have comparable precious metal loadings.

- DPF or Diesel Particulate Filter
This material can be split into two classifications. High-Grade that deserves the effort to recoup the PGMs, as well as Low-Grade that costs even more to recover the PGMs than the returns are worth. Additionally, notable is that several smelting centers are having problems processing this material as the high silicon carbide content is causing issues with arc furnaces, causing added fees for reuse.
- Aftermarkets
These converters are substitutes for when the OEM Converter falls short. The PGM loadings of aftermarkets are 90 percent less than OEM products; however, while the loadings of rare-earth elements are one-tenth of the OEM, they are made from the very same cordierite ceramic base.
- Grains
These converters were the very first on the market as well as were most typically discovered on light-duty vehicles. While there are not that many left for recycling, they are generally refined independently as the loadings of precious metals are more detailed to aftermarket degrees, using a precise assay value.
Up until late, it has been challenging for the majority of auto catalyst recyclers to have enough quantity of product to run each of these products in separate assays. This is since the majority of refiners are set up to refine 2,000 to 8,000 pounds weight dimensions.
