PowderRange® GammaPrint® -1100

PowderRange GammaPrint-1100 is an age-hardenable heat- and corrosion-resistant nickel-base superalloy powder purposefully designed for additive manufacturing. GammaPrint-1100 has excellent printability and derives its strength and creep resistance from a high-volume fraction of γ’-Ni₃(Al,Nb) precipitates (between 50 vol.% and 60 vol.% in the fully aged condition). With a composition specifically designed to form an alumina (Al₂O₃) layer when exposed to air, it is resistant to oxidation at temperatures up to 1050°C (1922°F). GammaPrint-1100 can be easily manufactured by laserpowder bed fusion (L-PBF) and electron beam melting (EBM) and resists cracking during printing and postprocessing heat treatment.
