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. 

There is about 3-7% of precious metals in most Catalytic Converters. These precious metals: platinum, palladium, and rhodium to control vehicular emissions. 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 records of over $16,000/ounce. Then when the Global Pandemic related to COVID-19 hit, prices dropped at low as $2,500 per ounce. Rhodium (Rh) is on the upswing and has started to level out to where it was in December of 2019.

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 inside, which can also depend on the manufacturer.

So there is not the 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 of the precious metals removed from it.
