Nickel Based Alloys

Since the melting temperature of nickel is 1453 °C, alloys formed with this element are used in high temperature applications. Nickel-based superalloys consist of 50-70% nickel (Ni) element. Cobalt (Co), zirconium (Zr), iron (Fe), molybdenum (Mo), niobium (Nb) and boron (Bo) elements were added to these alloys in order to increase their efficiency under usage conditions. These alloys are used in applications between 815 °C and 900 °C. These alloys are used in aircraft and gas turbines, rocket engines, spacecraft, thermal power plants, nuclear reactors and other high-temperature applications.
