The alloy has stable structure, and has satisfactory cold and hot processing forming and welding process properties, which is suitable for manufacturing high temperature plate bearing welding structural parts such as aeroengine combustion chamber and afterburner. Large plate structural parts manufactured with the alloy can be directly used without aging treatment after solution treatment.
Application
Aerospace;
Laser cladding;
The aero engine afterburner shell made of the alloy plate has been tested for a long time and put into mass production, which can reduce the weight of the engine and prolong the life.
The main products is spherical powder.
