How much rhodium is inside a catalytic converter?

That is not an easy question because it depends on the type of catalytic converter, the amount of use, and when it was manufactured. Even identical catalytic converters can have slightly different amounts of rhodium inside, and all various types will have varying amounts inside. When the RRCats price your catalytic converters, the quotes are based on the average rhodium recovery and other precious metals inside. When recycled, every catalytic converter could have different amounts of rhodium, depending on the manufacturer.

A fraction of an ounce of rhodium can be found inside each catalytic converter.

So there is not a precise amount of rhodium in every converter when they are built. This is why if you’re looking to get an accurate quote on the scrap catalytic converter you have, you must send our team pictures and serial numbers for us to look up the recovery rate. Hence, we know how to price it correctly based on all the precious metals removed.

What is Rhodium (Rh)?

…and how does it relate to Scrap Catalytic Converters?

Rhodium is one of the six platinum group metals: platinum, palladium, rhodium, osmium, iridium, and ruthenium. The primary use of Rhodium (Rh) is in catalytic converters designed to clean vehicle emissions. 

About 3-7% of precious metals are in most Catalytic Converters. These precious metals control vehicular emissions by controlling platinum, palladium, and rhodium. However, these precious metals are costly and add to the cost of catalytic converters and their worth.

Rhodium (Rh) has been on a rollercoaster ride for the last few years; it has continued to hit over $16,000/ounce records. Then when the Global Pandemic related to COVID-19 hit, prices dropped to $2,500 per ounce. Rhodium (Rh) is on the upswing and has started to level to where it was in December 2019.
