Product Description Product Description IntroductionLORK is a alloy manufacturer with 20 years of manufacturing experience. GH4720Li superalloy (Udimet 720Li in the United States) is a Ni-Cr-Co based deformation superalloy strengthened by precipitation of face-centered cubic γ′-Ni3(Al, Ti) phase. It has high strength, fatigue resistance and creep resistance, good corrosion resistance, oxidation resistance and long-term structural stability between 650~750oC[1-2]. Therefore, GH4720Li superalloy is mainly used to manufacture high-performance forged turbine disks for aircraft engines used below 750oC, and can also be used in new generation strategic missiles and high-thrust rocket engine power units. The United States has used this superalloy as a high-performance turbine disk material in advanced aircraft engines such as BR700, EJ200, AE2100, AE3007, T406 and T800[3]. my country began to develop GH4720Li superalloy in 2002. In-depth research has been conducted on the process, structure and performance of this alloy, and it has been applied to more than ten types of advanced aircraft engines.China GH Series GH4720Li Applications GH4720Li alloy is suitable for engine integral turbines, discs, ground gas turbine turbines, discs and other parts working below 750 degrees Celsius.?
