Recently, the demand for turbochargers in the automobile industry is increasing worldwide because of the emission regulations in Europe and the expansion of the Asian car segment. As we all know, compressor wheel is the main unit of a turbocharger. It requires not only high durability, but also high dimensional accuracy.
On the other hand, as turbocharger performance has improved, customer expectations in terms of levels of quality have risen enormously. Because they turn at speeds in the excess of 200,000 rpm, there is a need, not only for high durability, but also for high dimensional accuracy, and particularly for product of initial balance. Due to this reason, Niitsu Turbo Industries has developed a new compressor wheel which is called ARUMAITO® Compressor Wheel which produces better performance, higher durability, increased in surface hardness, higher density and good resistance heat.
With the on-going trends for smaller size and higher power for passenger and commercial vehicle turbochargers, there will be a need for compressor wheels to withstand higher speeds and temperatures than at present. Niitsu ARUMAITO® Compressor Wheel is being reinforced by a solution treatment and an aging treatment which results a good resistant strength, heat and greater performance. It would not deformed or broken by fatigue even by using it at a temperature of as high as 200°C.
Niitsu ARUMAITO® Compressor Wheel is made from 354 heat treated aluminium process. The compressor wheel is what delivers the dense pressurized air to the engine and it is one of the most important criteria for a quality turbocharger. Computer aided design allows for new blade combinations and specifications to be created to maximize airflow efficiency and pressure.
Niitsu ARUMAITO® Compressor Wheel is thus much stronger than conventional wheels and also allows a better balancing of the wheel due to a higher density.
