Mazda CX 7 catalytic converter scrap price and precious metals inside of the catalyst

For more than a decade, Mazda CX 7 catalytic converters have been installed on the manufactured cars. Besides Mazda, almost every other manufacturer tries to prevent environmental issues and equip their vehicles with catalytic converters or simply catalysts. Catalysts were made to perform one simple function - exhaust cleaning. Later, when they were developed well enough, most of the catalysts were classified into different sections. Depending on the quality of the catalyst, so-called ‘Euro’ environmental standards were applied. Toxic components are converted into harmless nitrogen, water and carbon dioxide under the influence of high temperatures, with the participation of oxygen and catalytic substances. In the role of the latter platinum groups - rhodium, palladium and platinum, thanks to which the car is much less polluting.

The catalytic converter looks like a bulge on the exhaust pipe and is easy to see when looking under the underside of the vehicle. Inside the thermally insulated body there are small ceramic or metal honeycombs, on the surface of which a thin layer of precious metals is applied. At a catalyst temperature of 300 ° C and above, observing the proportions of the fuel-oxygen mixture, they accelerate redox reactions. The total area of ​​the honeycomb lattice is measured in tens of thousands of square meters. The mass fraction of metals on its surface is from hundredths to tenths of a percent of the weight of the unit. The price of a catalyst as a raw material for their extraction is determined by a number of factors:

• models of automobile catalysts over 15 years old are designed under less stringent environmental standards, contain less precious metals and more foreign substances;

• modern cars are designed for Euro-5, Euro-6 standards and are equipped with a honeycomb grid of a larger area;

• car manufacturers are constantly improving the quality of their engines. Newer models are often equipped with lower capacity cleaning parts, resulting in lower palladium and rhodium content in newer catalytic converter models;

• three-chamber catalysts are more advantageous for platinum recovery.

Used Mazda CX 7 catalytic converter cost

Factory new catalysts are usually not being sold at aftermarkets or any other place. However, dealing with a used Mazda CX 7 catalytic converter is a common thing. Recycling values and prices for used catalysts can be quite attractive. The best thing for a reseller to do is to find more information online and dig into the manner deeper.
