Inconel 783 / Alloy 783 / UNS R30783
An oxidation resistant low coefficient of thermal expansion (low CTE) superalloy developed for gas turbine applications.
The alloy is strengthened by a precipitation-hardening heat treatment made possible by additions of niobium and aluminum. In addition, the aluminum content provides excellent resistance to oxidation at high temperature.
The alloy’s density is 5% less than those of superalloys such as INCONEL alloy 718. The combination of low expansion, high strength and excellent resistance to oxidation makes the alloy especially useful for gas turbine and steam turbine components.
The low expansion enables closer control of clearances and tolerances for greater power output and fuel efficiency.

I am earning my own wedding day band from Inconel X-750 just to be diverse. The material is a agony to do the job with thanks to the superior nickel/chromium articles. The lathe is a LeBlond “dual generate” with an Aloris-copy device article. I built an adapter for the one.25″ boring bar socket to sleeve it down to a 5/8″ side-lock drill shank. I utilised an indicator to sweep the device holder, inserting it instantly on center. The drill is a Seco CrownLoc As well as with .625″ tip, running at around 80sfm, hand feed with plenty of stress, and drenched in reducing oil (not demonstrated in pic). Chips had been astonishingly limited of course, I had to withdrawal the device numerous moments to eliminate chips, due to the fact they weren’t becoming flushed by coolant.
