High-temperature performance is not the only reason to choose a product like CuproBraze. Another advantage is the lower airside pressure drop. It's estimated that a copper-brass heat exchanger will have a 20-30-percent-lower air-pressure drop compared to aluminum.

A CuproBraze CAC withstands elevated temperatures better than an aluminum CAC, and the CuproBraze design removes heat more efficiently.
Conclusion
The good news is that the new, clean-burning diesel engines will be nearly as clean as gasoline engines. If they can be made even cleaner then increased use of diesel engines in SUVs, minivans, and light trucks can be expected and consumers will benefit from the greater fuel efficiency and durability of diesel engines compared to gasoline engines.
The bad news is that the new clean diesel engines will be more complex and hotter underhood than ever before. Reducing both NOx and PM emissions is complex because the typical approaches are contradictory. Lower combustion temperatures are needed to reduce NOx emissions, but high combustion temperatures are required to reduce PM emissions.
Whatever type of clean diesel engines are developed in the next few years to meet the stringent reductions in emissions, it wouldn't surprise us if CuproBraze technology is likely to play a vital role as the material system of choice for advanced cooling systems and exhaust aftertreatment equipment.
