Material of Our Turbocharger

Turbine wheel

The turbine wheel of the turbocharger belongs to the centrifugal series which means the rotating speed of the turbine wheel will be very high. The materials of turbine wheels would be very strictly to choose. The recommendation for this type of turbine wheel is to choose low density and light-weight. Except for that, the rigidity of the turbine wheel's material is supposed to be better and more reliable.

 

Beaver-T 's turbine wheels tend to use the K418 which is also called Inconel 713C as our raw materials. This material is Nickel base alloy. The theoretical bearing temperature of Inconel 713C is 950°C. By using Inconel 713C as raw material, the turbine wheels are enabled to high heat resistance.

Beaver-T also provides the Mar-M246 turbine wheels option for customers. The Mar-M246 material also is a type of Nickel base alloy. Compare to Inconel 713C, it has higher heat resistance. The theoretical bearing temperature of Mar-M246 is 1345°C. When the exhaust temperature exceeds 1000°C, we recommend our customers to apply material MAR-M246 turbine wheel, especially for turbochargers for racing cars.

Compressor Wheels

The most common material for turbocharger compressor wheels has been aluminum alloys. The aluminum alloys that we use can resist up to 300°C.

 

Beaver-T also offers Aluminum billet compressor wheel and Titanium billet compressor wheel options for customers who focus on performance. They have higher demand on strength of extension or heat resistance of the billet compressor wheel.

 

We use advanced 5-axis machines to process the billet compressors. Also, we tend to use 7075 as raw materials for the aluminum billet compressor wheels. These materials can provide more essential strength and reliability at extremely high boost pressure than the common compressor wheel.

 

Titanium billet compressor wheel has less weight than aluminum billet which means it has less rotation friction than a turbocharger. Also, it will also handle higher heat and withstand higher pressures.
