Turbine Housing

                         Turbine Housing

In terms of the advantages of Ni-Resist cast iron, many turbine housings are made by this type of material. Turbine housing for automotive gasoline powered engines. The Ni-Resist cast iron is D-5S.

 

Turbocharger casing for passenger automobiles is made of Ni-resist iron. Engine sizes range from 0.6 liter to about 2.0 liters. Weights 1.5kgs to 5.0kgs. Ni-Resist D2 for smallest cast iron on left, Ni-Resist D-5S for others. Turbocharger guide wheel for automotive engine Ni-Resist D-5S. 

 

Cylinder heads of Ni-Resist alloys resist corrosion from water and combustion products and have good metal-to-metal wear behavior. Ni-Resist finds side spread use as insert rings in aluminum alloy pistons. 

 

Water pump impellers and bodies offer another appropriate use for Ni-Resist alloys in engines. With increase in power, modern water pumps must operate at higher velocities than in the past. Higher water temperatures and pressures many increase the corrosion hazard and higher speeds can cause increased erosion damage. 

 

Some of the more frequent applications are:

Cylinders liners

Diesel engine exhaust manifolds

Exhaust valve guides

Gas turbine housings, stators and other parts

Insert rings and hot spot buttons for aluminum alloy pistons

Turbocharger housing, nozzle rings, heat shields and other parts

Water pump bodies and impellers
