GH4033 is a high-temperature alloy formed by adding aluminum and titanium to a nickel chromium matrix to form a Y-phase dispersion strengthened alloy. It has sufficient high-temperature strength at 700-750 ° C and good oxidation resistance below 900 ° C.
This alloy is used to make working blades, turbine disks, and other high-temperature load-bearing components for aircraft engines.
