CM247 high-temperature alloy powder
CM247 high-temperature alloy powder
CM247 is a γ′ phase-strengthened nickel-based superalloy with excellent high-temperature strength, creep resistance, oxidation resistance, and hot corrosion resistance. It is widely used in extreme high-temperature environments such as aero-engine turbine blades and gas turbine hot-end components. Its high volume fraction of γ′ phase (≥40%) and stable carbide distribution enable it to maintain stable mechanical properties in the temperature range of 980–1050°C, making it particularly suitable for lightweight, integrated high-temperature components manufactured via additive manufacturing.
