ACE/61/-/48 - Heat Resisting Alloys for Aerospace Purposes

Sector: Manufacturing

Categories: Non-ferrous alloys | Aerospace construction materials. General | Aerospace coatings and related processes | Aerospace construction materials | Steels | Fluid storage devices | Titanium | Paints and varnishes | Aerospace construction components | Aerospace electric equipment and systems | Materials. Other | Steels. Wire, wire ropes and link chains | Ferrous alloys

Overview: Under the direction of ACE/61, to be responsible for all matters relating to the standardisation of wrought and cast heat-resisting alloys for aerospace purposes, with particular reference to the HR series of British Standards and formulating the United Kingdom input to European and international standards organisations where required.
