Inconel 718
Inconel 718 is known for its outstanding high-temperature strength, creep resistance, and corrosion resistance. The material can withstand operating temperatures above 700°C while maintaining excellent fatigue and fracture resistance. Through additive manufacturing, GH4169 can produce parts with complex geometries and is widely used in aerospace engines, gas turbines, high-temperature molds, and high-performance industrial components.
Disadvantages: High cost; complex heat treatment process; thin-walled structures require careful design; default surface roughness Ra10–12.
