Superalloy for Powder Additive Manufacturing (3D Printing)
Superalloy used in powder additive manufacturing (i.e., 3D printing) mainly refer to metal materials that can maintain excellent mechanical properties, oxidation resistance and structural stability under high-temperature (usually >600℃) and stress environments.
Superalloy for Powder Additive Manufacturing Introduction
Superalloy used in powder additive manufacturing (i.e., 3D printing) mainly refer to metal materials that can maintain excellent mechanical properties, oxidation resistance and structural stability under high-temperature (usually >600℃) and stress environments. These alloys are widely applied in high-end fields such as aero-engines, gas turbines, nuclear power and chemical engineering, adapting to the complex structural manufacturing needs of core components in these industries.
Nickel-based High Temperature Alloys
The most widely used type, featuring excellent high-temperature strength, creep resistance and oxidation resistance.
Typical grades include:
- IN718 (GH4169): Precipitation-strengthened type with excellent comprehensive performance, one of the most mature high-temperature alloys in additive manufacturing.
- IN625 (GH3625): Solid-solution strengthened type with outstanding corrosion resistance, suitable for laser cladding and 3D printing.
- CM247LC, K438: Used for high-temperature load-bearing components such as turbine blades.
- FGH95, FGH96: Independently developed powder metallurgy high-temperature alloys in China, used for aero-engine turbine disks.
Cobalt-based High Temperature Alloys
Excellent performance in high-temperature oxidation and hot corrosion environments, suitable for combustion chambers, guide components, body implants etc. Cobalt metal powder grades produced via the gas atomization method, such as CoCrF75
CoCrF75 is suitable for the production of CoCrMo implants.Cobalt-based metal powder alloy for medical applications: very good biocompatibility, very high corrosion resistance.
