UDIMET® alloy 720 is the latest iteration of a sequence of alloying investigations of the Nickel Chromium Cobalt group, employing the solid solution strengthening elements such as Molybdenum and Tungsten, with the precipitation hardening capability of controlled additions of Titanium and Aluminium. The alloy is available in controlled grain size bar for blading plus conventional forging billet and atomised powder disc billet.
