The addition of aluminum can increase the strength of copper-nickel by conventional precipitation hardening mechanisms. Cu-Ni-Al alloys, principally consisting of Ni3Al and known as gamma prime, are used in shafts and bearing brushes, bolting, pump and valve trim, gears and fasteners. Because of its excellent impact and fatigue resistance NFL14702 is mainly used by both marine and aeronautical industry.
