New Materials

Brief Particulars of Recently Introduced Materials likely to have Aircraft, Missile or Space Vehicle Applications. Two new nickel‐based casting alloys—EPK 36 and EPD 16—which have been developed in the Rcsearch Laboratories of the International Nickel Company (Mond) Ltd. are now under experimental production at the Hereford Works of Henry Wiggin and Co. Ltd. Specially developed to meet demands for improved high‐temperature service and intended for the manufacture of precision investment‐cast rotor and stator blades in aircraft gas turbines, both the new alloys are vacuum‐melted and vacuum‐cast.
