China High temperature casting alloy manufacturer and supplier:Breakthrough in casting technology for key components of commercial aviation engines Hay:T02GZAJ

In the absence of various domestic research and development technologies that can be used for reference, and the technology and technology of foreign countries strictly sealed, GZAJ Precision Casting completely relies on its own production and technical capabilities. After nearly two years of unremitting efforts, it has overcome the CJ1000 commercial culmination Compared with the key components of aero engine, the casting technology of the high-temperature alloy integral casing has reached the peak of the current domestic high-temperature alloy precision casting technology, filling the gap in the domestic technology of large-scale passenger aircraft engine high-temperature alloy integral casing casting.

Superalloy refers to high-temperature metal materials that work for a long time under 760-1500 ℃ and certain stress conditions. It has excellent high-temperature strength, good resistance to oxidation and hot corrosion, good fatigue properties, fracture toughness and other comprehensive properties. It has become an irreplaceable key material for the hot-end components of military and civilian gas turbine engines. China started late in the research and use of high-temperature alloy materials, and has a large gap compared with similar foreign industries. From the perspective of national strategic development, it is urgent to accelerate the research and use of high-temperature alloy materials and shorten the gap with similar foreign industries. Similarly, the development and production of the Chinese's own large aircraft is the dream of several generations of aviation people in New China. It is a symbol of a country's comprehensive strength, and several generations of aviation people have devoted their lives to this end. The supporting aero engine is like the "heart" of human beings, which is the core part of the aircraft. The high-temperature alloy integral case used by the COMAC large passenger aircraft engine developed by GZAJ Precision Casting Co., Ltd. 

During the two-year development process of AVIC Anji Precision Casting, it adopted a series of domestic advanced and international-level advanced technologies, and for the first time developed the largest and most complex high-temperature alloy precision casting box castings in China, thus mastering The manufacturing technology of large-scale and complex thin-walled integrated casings for commercial large bypass ductile engine superalloys has reached the international advanced level.
