Turbo compressor blade?

[jwilliams3]

I was wondering what material is used to manufacture the Holset Turbo Compressor blade(s)/fan on our Cummins Turbo Diesel?



Anyone know? Some sort of Alloy?



Thanks in advance.

Compressor Wheel (Impellor) :

typically cast aluminium alloy (Cu-Si, solution treated & aged)



Turbine Wheel :

high nickel superalloy

grain structure critical to achieving life





From the Holset website. Check it out, lots of useful info. And a tidbit of info, Cummins actually owns Holset
