What Makes DZ125 Alloy Powder Essential for Turbine Blade Manufacturing

Published by HUAXIAO TECH manufacturer

For aero engines and industrial gas turbines, the demand for materials with high-temperature strength, fatigue resistance, and oxidation protection is critical. DZ125 alloy powder, a nickel-based superalloy, is engineered specifically for directional solidification and single-crystal components used in turbine blades.

Optimized for High-Temperature Performance

DZ125 is a second-generation nickel-based superalloy containing key elements such as Al, Cr, Co, W, Mo, Ta, Re, and Hf. Its unique composition allows for:

• Excellent creep and rupture resistance above 1000°C

• Stable microstructure under long-term thermal exposure

• High resistance to fatigue crack propagation

These characteristics make it the material of choice for high-performance turbine airfoils.

Exceptional Oxidation and Corrosion Resistance

The presence of aluminum and chromium forms a stable oxide film, enabling DZ125 to resist:

• High-velocity hot gas oxidation

• Sulfide corrosion in aggressive combustion environments

• Thermal fatigue from cyclic heating and cooling

This reliability is crucial for engine components operating under extreme conditions.
