Superalloys find widespread application in gas turbines for aerospace applications, where they are used to produce blades and guide vanes designed to operate under the most demanding conditions. We are particularly proud of our position as one of the world’s largest and most respected manufacturers of superalloy barstock to the aerospace industry. We have sites in the UK (Ross & Catherall near Sheffield) and USA (Certified Alloy Products Inc. or CAPI in Long Beach, California) dedicated to this technology. In fact, the company offers a wide range of vacuum induction melting (VIM), vacuum induction degassing pouring (VIDP) and air induction melting (AIM) capabilities. Our vacuum furnace sizes range in capacity from 500 kg to 8000 kg (1,100 – 8.8 tons).
Alloys produced typically contain nickel with additions of (among other things) cobalt, chromium, aluminium, titanium, molybdenum, niobium, tungsten and tantalum. Included in Doncasters’ capabilities are alloys specifically designed for directional solidification and single crystal applications.
