Release time:

2025/09/15

1. Nickel (Ni): Provides high-temperature strength and oxidation resistance.

2. Iron (Fe): Mainly used in iron-based high-temperature alloys to provide matrix strength.

3. Cobalt (Co): Enhances high-temperature strength and corrosion resistance.

4. Chromium (Cr): Improves oxidation and corrosion resistance.

5. Molybdenum (Mo) and Tungsten (W): Improve high-temperature strength and hardness.

6. Aluminum (Al) and Titanium (Ti): Enhance the alloy's precipitation hardening effect by forming a γ' phase (Ni3(Al,Ti)).

7. Niobium (Nb): Forms a strengthening phase, improving high-temperature strength.
