well they are made with a wax molding basically then covered with sand and alcohol mix ---- called slurry then heated and the wax melts out then titanium or steel is poured into it then you have the finished product i sandblast them.

 

Hobart 4x4 dish racks, just another lowly dishwash boy

 

Steel for compressor wheels? Sure. You probably mean an alloy of ALUMINUM.

 

so what are they for? Big diesels?

 

Ahh....Lost wax. Thats what i figured. Same way mot propellers for boats are made.

 

yea im going through al the casting methods at school now, first year of mechanical engineering

 

1993ferio,

I don't suppose you could machine a custom compressor wheel out of beryllium for me ( just kidding that ---- messes up your lungs for life if you inhale the dust )

 

well we deal with three metals... Titanium, Steel, and Titanium Aluminide. im not sure what those are but my bet is on titanium aluminide. and most the parts we make are for boeing and rolls royce airplane engine parts. ill take some pics of them tomorrow.

 

alright..meat processors!!!! burgers please!!

 

Theyre titanium aluminide as most of the english turbos are using now and perhaps where the brand name "TiAL" comes from Dunno. But, its an instance where casting titanium is possible with the help of the aluminum alloy as well. Do you have a connection there? I need a new compressor wheel on a rare german supercharger I have.
