I thought BMW started putting turbonators in.

They make so much more horsepower than regular turbos.

In all seriousness I have no idea what the turbos are made of.

Basically aluminum, steel, and inconel...

I don't think Aluminum is going to cut since it has a melting point (liquid) at 1075 F.

Titanium is typical not particle since casting it is extremely expensive. It has to be done in a vacuum. Cost way more to process than it is worth out of the ground.

The turbine housing is NiSiCr (Ni-resist) cast alloy (e.g. D5S - 36%Ni;5%Si;2%Cr, D2B in diesels). It can be also made of Si-Mo ductile iron coated with a heat resistant cover layer of self-diffused alloy comprising Ni--Cr alloy including C, B and Si.

Turbine rotors are Ni-based steel (Silicon Nitride - Si3N4, Inconel) or TiAl (titanium aliminide) alloy (MHI) or ceramic.

Compressor wheels can be made of high-strength aluminum or titanium, also TiAl and ceramic.

The compressor housing is Aluminum alloy casting.

The shaft is stainless steel, can't be aluminium because of the heat on the turbine side.

Is it aluminum, titanium, metal alloy?
Maybe we can get some real answers.

What a great comunity this is!

Sorry, dude. Might as well Google this one.
I've been doing that this morning....

Not saying people are dumb on here, just saying that it's a rather odd technical question. Since they are Mitsubishi turbos, maybe the OP or someone can research it under that and get some answers on Google?
I am researching a bit now. I am just curious mostly. I know there are a few people who know more of the technical issues, so I figured I would throw it out there....

I agree with Orb, it'll be an inconel alloy to take the heat and the effects of creep. Inconel 718 is a good one for example.

Nothing else can take that kind of temp, Alum would melt. Alloys of steel would creep.

Ti is no good, good for corrosion and weight but but too high coeff. of expansivity.

The Blackbird Spyplane was all Ti, the fuel pissed out of the plane when they filled it on the ground. The plane swelled at higher speeds due to skin friction and then it was good to carry more fuel.

threr are Mitsu torbos in N54. I've seen an announcement that in the X6 biturbo BMW will use Honeywell turbos.
