How Much Rhodium is in A Catalytic Converter

How Much Rhodium is in A Catalytic Converter? All of our autos have a different quantity of rhodium in them. As a result, the answer to this question is dependent on some variables, the most important of which are the model and manufacture of the vehicle in question, as well as the engine. The same engine may be used in several nations, but the converters for each country are different. A catalytic converter has an average weight of 1.2 kg or 2.2 pounds and an average rhodium content of 1-2 grams.



Rhodium is an automobile chattel that can’t be without. The atomic symbol for this white-toned precious metal (also known as Rh) is Rh. This metal is part of the platinum family. Your automobile emits pollutants that are dangerous to people, but the catalytic converters in your car remove them, so your car doesn’t contaminate the environment. Nonetheless, do you know the ingredients that remove the pollutants from the exhaust?

The rhodium and palladium work together to remove the poisons even before fumes are discharged into the atmosphere, making them a crucial ingredient. Generally speaking, the most common use for rhodium is in automobile catalytic converters, which are meant to reduce pollution. Nitrogen oxide in engine exhaust is reduced by rhodium, palladium, and platinum, which are often used in combination. Our cities’ air quality would be far worse if rhodium catalysts were not used.

The only places where you can get Rhodium are in tiny amounts as a by-product of the mining of platinum and nickel, mostly in Russia and Canada. For its rarity and difficulty in obtaining from sources like jewelry and catalysts, it is in high demand.

It took approximately a century for rhodium to make a comeback in high-temperature scientific instruments after being mostly ignored for decades. Things began to change dramatically in the mid-1970s with the introduction of catalytic converters, which reduced the amount of pollution emitted by automobiles during the combustion process. Rhodium’s rarity explains why it’s a popular investment metal today, pricing at around $13,800.00 per ounce.

Catalytic converter rhodium content - how much is there?

All of our autos have a different quantity of rhodium in them. As a result, the answer to this question is dependent on a number of variables, the most important of which are the model and manufacture of the vehicle in question, as well as the engine. The same engine may be used in several nations, but the converters for each country are different.

A catalytic converter has an average weight of 1.2 kg or 2.2 pounds and an average rhodium content of 1-2 grams.

The price of rhodium varies greatly depending on the purity of the metal, although it may be cheaply obtained by recycling existing converters.

The price of rhodium has fluctuated the greatest during the last six months. With a price-per-gram of $427.65, gold is now trading at about $13,300 per troy ounce; daily price movements of $300 per troy ounce are the norm. Manufacturers of catalytic converters are doing all they can to prevent utilizing rhodium.

Rhodium use for emissions controls peaked at a certain point in time, and I’m sure that older models of autos are worth a lot of money. On average, around five years ago, rhodium sold for roughly $575 per Troy ounce/18.50 cents on the dollar (per gram).

For one thing, metal prices may change greatly; not only do they fluctuate in value, but they also fluctuate in volume and utilization ratio. The pricing and efficiency of certain metals and alloys may have a significant impact on the composition and design of catalytic converters.

As a result, each alteration entangles the manufacturer in federal agencies of retesting, re-certifications, and, no doubt, a load of new federal and state laws and regulations. As a result, it’s possible that producers may be unable to respond quickly to changes in PGM costs. Aftermarket manufacturers should take note of this.

Who Makes the Most Rhodium-Rich Catalytic Converters?

Most rhodium is found in vehicles with large engines or vehicles with many catalytic converters.

Even more, rhodium is used in expensive catalytic converters since rhodium is so valuable. The Toyota Prius has an expensive catalytic converter, making it an easy target for thieves.

All of these vehicles, including the Ferrari F430, the Lamborghini Aventador, the Ford Mustang, and the Ram 2500, feature expensive converters. There is a need for more catalytic converters since the cars have large engines.

As a result, if a car needs more catalytic converters, it will almost certainly need more rhodium metals. Alternatively, large catalytic converters also need more rhodium to effectively remove the exhaust gasses from the exhaust system.

Due to stricter emission regulations, the demand for rhodium has risen as a result of an increase in toxicity in automotive exhaust.

A shortage of rhodium is currently developing because of the high demand from the car industry to meet rigorous emission regulations. Catalytic converter thefts have been on the rise due to a lack of supply, which has made the product expensive.

Are the properties of Rhodium derived from an old catalytic converter susceptible to degradation?

The honeycomb section of the converter contains rhodium, which may be readily recovered via recycling. Catalytic converter rhodium retains all of its characteristics and strength when recycled.

Air, moisture, and acids have the least effect on rhodium. Thus, the acidic poisons created by the diesel exhaust will not harm the metal.

In order to make acetic acid, the metal performs a process known as catalytic carboxylation. There are a few metals that are as hardy as this one.

The recycling firm should have the most up-to-date technological systems and be power. An efficient waste management system is also needed to prevent environmental contamination at the cost of metal.

Why Has Rhodium Gone From Being Cheap to Being Expensive?

As a result of stricter pollution regulations, the demand for rhodium has soared. As the car industry scrambles to fulfill more strict emission standards, it’s running into a supply shortage.

As a result of the scarcity, its price has more than doubled, and it is now more expensive than gold. For the same amount of money, you could buy three Toyota Innovas or three Kia Carnivals. The theft of rhodium catalytic converters in the United States has been sparked by a shortage of metal.

Because South Africa was the world’s biggest producer of rhodium, the closure of the country’s mines added to the metal’s price. The rhodium price has been influenced by a lack of supply owing to the decline in metal mining.

In addition, the availability of rhodium is decreasing, resulting in an increase in the price of the products.

Since the corona epidemic, there has been a lot of investment in the mining industry. A few of the underground coal mines in South Africa have not yet been completely operational.

Rhodium metal is in high demand from automakers in Europe, Asia, and the United States as a way to fulfill increasingly strict standards for air quality. Because of its strong corrosion resistance and low price, this metal is a popular choice for exhaust gas cleaning in automobiles.

The chemical and physical features of this substance also make it useful in other fields, increasing the market for it even more.

Rhodium is difficult to remove from its ore, and this makes it more expensive. The fluctuation of its price may be a normal occurrence. This could lead to a shortage of metal, resulting in even higher prices, as a result of the anticipated price rises.


Rhodium is an essential ingredient in automobile catalytic converters, which remove pollution from the exhaust. Manufacturers are doing all they can to prevent utilizing the precious metal. Catalytic converter thefts have been on the rise due to a lack of supply.

What Is Rhodium’s Current Value?

According to the current market price of $290 per gram, real rhodium would cost above or below this. As an intermediary, you may purchase metal from miners and resell it to automakers for a profit.

Rhodium may appreciate in value in the future as a result of supply and demand concerns, making it a profitable investment to acquire and resell the metal.

However, if you’re hoping to sell an old catalytic converter, you may expect to get anywhere from $399 to $1500 at your local scrapyard.

Palladium, another very expensive metal, is said to be a contributing factor to the skyrocketing costs. Setting up your own recycling firm, on the other hand, will allow you to sell the catalytic converter’s metals for a profit.

Why does rhodium have such a high cost?

Rhodium’s value will almost certainly stay high as long as it is in such short supply due to the great demand for it. The price of rhodium is going to be very volatile in the near future. The rhodium shortage is expected to become worse over time.

As a result, the great demand for rhodium and its widespread use drive up its price. Catalytic converters, which remove carbon dioxide and other pollutants from the atmosphere, are required by strict automotive production standards.

Consequently, its price has continued to rise as a result of the increased demand for this precious metal. Rhodium is now selling for $290 a gram. As a result of the coronavirus pandemic and supply chain disruption, the metal’s supply has been adversely affected by the increased demand from automobile manufacturers and reduced mining output.

The amount of rhodium in a catalytic converter has been established, as well as the cause for the rise in demand. In addition, the environmental significance of rhodium in catalytic converters is undeniable.
